  • DNA Evidence and Paternity: Establishing Paternity Beyond Reasonable Doubt in Rape Cases

    In People v. Umanito, the Supreme Court addressed the crucial role of DNA evidence in rape cases involving disputed paternity. The Court allowed DNA testing to determine if the accused was the father of the child born from the alleged rape. The accused filed a Motion to Withdraw Appeal after a 99.9999% probability of paternity, leading to his conviction. This decision underscores the conclusive nature of DNA evidence in resolving doubts in criminal cases and determining paternity.

    The DNA Verdict: Can Science Resolve Claims of Rape and Alibi?

    This case arose from the rape charges filed against Rufino Umanito. He was convicted by the Regional Trial Court (RTC) and later affirmed by the Court of Appeals. Umanito then appealed to the Supreme Court, citing inconsistencies in the prosecution’s claims and asserting an alibi. Given that the alleged rape resulted in the birth of a child, BBB, the Supreme Court recognized the necessity of determining whether Umanito was the child’s father. The Court applied the recently promulgated New Rules on DNA Evidence to resolve the conflicting assertions between the prosecution and the defense.

    In its Resolution dated 26 October 2007, the Supreme Court highlighted that advancements in genetics provide a reasonable way of ascertaining whether the accused is the father of the victim’s child. The Court emphasized that if DNA testing conclusively proves the accused is not the father, this may establish reasonable doubt and warrant an acquittal. Thus, the Court ordered Umanito, the complainant AAA, and their child BBB, to undergo DNA testing in accordance with the New Rules on DNA Evidence.

    The RTC of Bauang, La Union, proceeded with the directives from the Supreme Court. Hearings were conducted to assess the feasibility of DNA testing. Both AAA and BBB expressed their willingness to undergo the examination. With the concurrence of both parties, the National Bureau of Investigation (NBI) was selected to conduct the DNA testing. The RTC issued an order on even date specifying the protocol for the taking of biological samples from AAA, BBB, and Umanito to safeguard the integrity of the process and ordered that proper chain of custody be maintained throughout the procedure.

    Key measures were mandated, including collection by a neutral third party, proper identification of the tested parties during sample collection, and protection of the samples with tamper-evident tape. Each individual in possession of the samples was responsible for thoroughly inspecting for tampering and explaining their role in sample custody. These precautions ensured the reliability and accuracy of the DNA testing results. Once secured, the NBI’s forensic chemist then used buccal swabs taken from the parties as the primary source, as well as blood, to secure a reliable result and prevent contamination of the DNA samples.

    At a subsequent hearing, the NBI forensic chemist testified, presenting the DNA analysis results, showing the probability of paternity was 99.9999%, which means that there was a complete match in all of the fifteen loci tested between the alleles of Rufino Umanito y Millares and BBB. No objections were interposed by the defense to the exhibits offered in evidence.

    Under Section 9, A.M. No. 06-11-5-SC, if the value of the Probability of Paternity is 99.9% or higher, there shall be a disputable presumption of paternity. Despite this presumption and an opportunity to present evidence to rebut it, Umanito chose not to dispute the findings of the Forensic Chemistry Division of the National Bureau of Investigation. This decision was particularly significant because, given the accuracy of the procedures and the results obtained, Umanito’s alibi, combined with his denial of a romantic relationship with AAA, was decisively contradicted by the scientific findings. It firmly established that he had engaged in sexual relations with the complainant and fathered her child.

    Ultimately, Umanito filed a Motion to Withdraw Appeal dated 16 February 2009, an action that signified his acceptance of the lower courts’ judgments. The Supreme Court, noting the alignment of the DNA testing results with the conclusions reached by the RTC and the Court of Appeals, saw no reason to withhold granting Umanito’s Motion to Withdraw Appeal, resulting in the closure and termination of the case.

  • Circumstantial Evidence and DNA in Rape-Homicide Cases: Reassessing Guilt Beyond Reasonable Doubt

    In People v. Pascual, the Supreme Court affirmed the conviction of Alfredo Pascual for Rape with Homicide, emphasizing the sufficiency of circumstantial evidence even when DNA evidence is inconclusive. The court underscored that while DNA analysis holds significant value, its limitations, such as sample contamination, do not automatically overturn a conviction when a robust chain of circumstantial evidence strongly supports the accused’s guilt. This ruling reinforces the principle that the totality of evidence, rather than any single piece, determines guilt beyond a reasonable doubt, and also clarifies how courts should balance scientific evidence with traditional forms of proof.

    Beyond the DNA: How Circumstantial Evidence Sealed a Fate in a Rape-Homicide Case

    The case of People of the Philippines vs. Alfredo Pascual revolves around the tragic death of Lorelyn Pacubas, who was found raped and murdered in her home. The prosecution built its case on a series of interconnected events, each piece of evidence contributing to a compelling narrative implicating Alfredo Pascual. Although DNA evidence was inconclusive, the Supreme Court scrutinized the collective weight of circumstantial evidence to determine if Pascual’s guilt was established beyond a reasonable doubt. This case navigates the complex intersection of forensic science and traditional investigative techniques, providing insight into how courts assess evidence in the pursuit of justice.

    The facts presented by the prosecution painted a clear picture: Pascual was seen drinking near the victim’s residence on the night of the crime. Witnesses testified that he left the gathering multiple times, only to return, and eventually left for good. Shortly after, Pascual’s wife was seen chasing him, shouting for help, and indicating Pascual might have harmed Lorelyn. When witnesses entered Lorelyn’s room, they discovered her body in a state indicative of sexual assault and murder. The medical examination confirmed rape and death by asphyxiation.

    The defense countered with alibi and a DNA analysis that did not match Pascual’s profile to the samples collected from the victim. Pascual claimed he was at a friend’s house during the commission of the crime, a claim supported by a defense witness. The defense also highlighted the forensic chemist’s testimony that the DNA analysis was inconclusive due to contamination of the samples. This inconclusive result became a focal point for the defense, arguing that it cast reasonable doubt on Pascual’s guilt.

    The Supreme Court emphasized that, in cases of rape with homicide, both elements must be proven beyond a reasonable doubt. The court acknowledged that the crime often occurs in secrecy, making direct evidence scarce. In such cases, the prosecution may rely on circumstantial evidence, which, if strong enough, can lead to a conviction. Section 4, Rule 133 of the Revised Rules of Court specifies the conditions under which circumstantial evidence is sufficient for conviction:

    (a) there is more than one circumstance; (b) the facts from which the inferences are derived have been established; and (c) the combination of all the circumstances is such as to warrant a finding of guilt beyond reasonable doubt.

    Building on this principle, the Supreme Court meticulously examined the evidence. The Court noted the established facts that Pascual was drinking nearby, left and returned multiple times, and was later seen fleeing the scene by his wife Divina who also alerted witnesses with her shouts for help mentioning Pascual’s name: “Kuya tulongan mo ako si Boyet” (Brother help me, Boyet.) These facts, combined with the medical evidence of rape and homicide, created a chain of circumstances pointing to Pascual’s guilt. This approach contrasts with a reliance solely on the DNA evidence, which, due to its inconclusive nature, could not definitively exonerate him.

    The court also considered Pascual’s alibi, which it found weak and unconvincing. It noted that his flight from the scene and subsequent failure to report to authorities further indicated guilt. The Supreme Court reiterated that flight is often indicative of a guilty conscience, underscoring its importance in evaluating the totality of the evidence.

    Regarding the DNA evidence, the court acknowledged its importance but clarified its limitations. The forensic chemist testified that the vaginal smear sample was already subjected to serological analysis, which affected the integrity of the DNA. The court determined that the inconclusive DNA results did not outweigh the compelling circumstantial evidence presented by the prosecution. In this context, the ruling aligns with principles of evidence assessment, emphasizing the holistic evaluation of all available information. The ruling reinforces that the lack of conclusive DNA evidence does not automatically negate guilt when other substantial evidence exists.

    Ultimately, the Supreme Court affirmed the Court of Appeals’ decision, finding Pascual guilty of rape with homicide. However, due to the passage of Republic Act No. 9346, which prohibits the imposition of the death penalty, the Court sentenced Pascual to reclusion perpetua. This ruling underscores the enduring role of circumstantial evidence in the legal system and provides guidance on the assessment of DNA evidence within the broader evidentiary context.

    FAQs

    What was the key issue in this case? The key issue was whether the circumstantial evidence presented against Alfredo Pascual was sufficient to convict him of Rape with Homicide, even though DNA evidence was inconclusive. The court assessed if the chain of circumstances established his guilt beyond a reasonable doubt.
    What is circumstantial evidence? Circumstantial evidence is indirect evidence that requires the judge or jury to infer a fact in question based on other established facts. It consists of proof of collateral facts and circumstances from which the existence of the main fact may be inferred.
    Why was the DNA evidence inconclusive? The DNA evidence was inconclusive because the vaginal smear sample had already undergone serological analysis, which compromised the integrity of the DNA. This made it impossible to obtain a complete and reliable DNA profile.
    What did the witnesses testify to? Witnesses testified that Pascual was drinking near the victim’s residence on the night of the crime, left multiple times, and was later seen fleeing the scene by his wife. His wife was heard shouting, indicating Pascual might have harmed the victim.
    What was Pascual’s defense? Pascual claimed he was at a friend’s house during the commission of the crime (alibi), and the DNA analysis did not match his profile. He argued that the inconclusive DNA results cast reasonable doubt on his guilt.
    How did the Court address the issue of flight? The Court noted that Pascual’s flight from the scene and subsequent failure to report to authorities indicated a guilty conscience. It considered this behavior as an important factor in evaluating the totality of the evidence against him.
    What penalty did Pascual receive? Initially sentenced to death, Pascual’s penalty was reduced to reclusion perpetua due to the passage of Republic Act No. 9346, which prohibits the imposition of the death penalty in the Philippines.
    What were the other damages awarded to the victim’s heirs? In addition to reclusion perpetua, the Court ordered Pascual to pay the heirs of the victim amounts for civil indemnity, moral damages, actual damages, burial expenses, and loss of earnings. The amounts varied depending on the type of damage being compensated.
    What is res gestae, and why was it important in this case? Res gestae refers to spontaneous statements made during or immediately after an event that are considered reliable and admissible as evidence. In this case, Divina’s statements to Gorospe, like “May nagyari sa itaas at galing doon si Boyet” were considered res gestae because they were made spontaneously after she found the victim and concerned the immediate circumstances of the crime.

    This case serves as a reminder of the complexity of the legal system, emphasizing the importance of considering all available evidence in determining guilt beyond a reasonable doubt. The ruling clarifies the weight given to circumstantial evidence and how it can lead to a conviction, even when forensic evidence is not conclusive.

  • Unraveling Reasonable Doubt: The Role of DNA Evidence in Rape Cases

    In People v. Umanito, the Supreme Court addressed the critical role of DNA evidence in rape cases, particularly when paternity is in question. The Court remanded the case to the Regional Trial Court (RTC) to conduct DNA testing on the appellant, the victim, and the child born as a result of the alleged rape. This decision emphasizes the potential of DNA evidence to establish reasonable doubt and ensure a fair trial by either confirming or denying the appellant’s paternity, thus impacting the determination of guilt or innocence.

    The Paternity Puzzle: Can DNA Testing Break the Stalemate?

    Rufino Umanito was convicted of rape based on the testimony of the complainant, AAA. The appellate court affirmed the RTC’s decision, despite inconsistencies in AAA’s statements. Umanito appealed, asserting that the delay in filing the complaint and AAA’s questionable credibility cast reasonable doubt on his guilt. The defense argued that AAA might have filed the complaint under pressure from her mother, suggesting that the child was conceived with another man. Given these circumstances, the Supreme Court sought a definitive way to verify or disprove Umanito’s paternity through DNA evidence.

    The Supreme Court emphasized the significance of DNA testing in modern legal proceedings. DNA evidence, with its ability to link a suspect to a crime or exonerate the wrongly accused, offers a uniquely effective tool in criminal investigations. The Court referenced the New Rule on DNA Evidence, highlighting its purpose in facilitating accurate accounts of crimes, ensuring convictions of the guilty, acquitting the innocent, and maintaining the proper administration of justice.

    Drawing from previous rulings, the Supreme Court acknowledged the growing acceptance and reliability of DNA testing in the Philippines. Quoting People v. Yatar, the Court pointed out the advancements in DNA testing methods, such as the Polymerase chain reaction (PCR) amplification method by Short Tandem Repeat (STR) analysis, which allows for the reliable amplification of small samples. Building on this, the Court cited Herrera v. Alba, where DNA was described as the fundamental building block of a person’s genetic makeup, unique to each individual (except identical twins). These cases demonstrate a progressive shift towards integrating scientific advancements into the legal framework to enhance accuracy and fairness.

    In its resolution, the Court provided clear guidelines for the RTC in conducting DNA testing, referencing Section 4 of the Rules, which outlines the factors to consider when ordering DNA testing: the existence of a relevant biological sample, the validity of the testing technique, and the potential of the testing to produce new, relevant information. These considerations are designed to ensure the integrity and reliability of the DNA testing process. Section 5 of the Rules provides additional considerations:

    SEC. 5. DNA Testing Order. – If the court finds that the requirements in Section 4 hereof have been complied with, the court shall. — (a) Order, as appropriate, that biological samples be taken from any person or crime scene evidence; (b) Impose reasonable conditions on DNA testing designed to protect the integrity of the biological sample, the testing process and the reliability of the test results, including a condition that the DNA test results shall be simultaneously disclosed to parties involved in the case; and (c) If the biological sample taken is of such an amount that prevents the conduct of confirmatory testing by the other or the adverse party and where additional biological samples of the same kind can no longer be obtained, issue an order requiring all parties to the case or proceedings to witness the DNA testing to be conducted.

    The Supreme Court further instructed the RTC on evaluating the DNA results. Citing Sections 7 and 8 of the Rules, the Court emphasized the importance of assessing the chain of custody, DNA testing methodology, forensic DNA laboratory standards, and the reliability of the testing result. By addressing the critical need for evidence preservation as set forth under Section 12, The Rules provide an avenue for accountability and clarity within the entire testing process. Chain of custody, especially, is a key element to ensure the integrity of the DNA evidence.

    By remanding the case for DNA evidence reception, the Supreme Court sought to eliminate doubts surrounding Umanito’s guilt. The introduction of DNA evidence could potentially serve as a powerful tool to clarify the facts and ensure justice is served. Thus, the Supreme Court designated Deputy Court Administrator Reuben Dela Cruz to supervise the RTC’s implementation of the Rules, emphasizing the Court’s commitment to monitoring and evaluating the application of new evidentiary rules.

    In this case, the importance of modern technology in affirming or negating the facts of a case and creating reasonable doubt, which determines a case verdict, proves to be an advantage with great use in the Philippine judicial system.

    FAQs

    What was the key issue in this case? The key issue was whether DNA testing could be used to determine if the accused was the father of the child born to the rape victim, thereby establishing reasonable doubt regarding his guilt.
    Why did the Supreme Court remand the case to the RTC? The Supreme Court remanded the case to the RTC to conduct DNA testing, which could either confirm or deny the accused’s paternity and thus impact the determination of guilt or innocence.
    What is the significance of the New Rule on DNA Evidence? The New Rule on DNA Evidence provides guidelines for the admissibility and evaluation of DNA evidence in court, emphasizing its potential to provide accurate accounts of crimes and ensure justice.
    What factors should the RTC consider when ordering DNA testing? The RTC should consider whether a relevant biological sample exists, if the testing technique is scientifically valid, and if the testing has the potential to produce new, relevant information.
    What is ‘chain of custody’ in DNA evidence? Chain of custody refers to the documented chronological history of a biological sample, including how it was collected, handled, and analyzed, ensuring its integrity and preventing contamination.
    How will the DNA results be evaluated by the RTC? The RTC will assess the chain of custody, DNA testing methodology, forensic DNA laboratory standards, and the reliability of the testing result to determine the probative value of the DNA evidence.

  • DNA Evidence and Conviction: People vs. Yatar and the Standard for Admissibility

    In People of the Philippines vs. Joel Yatar, the Supreme Court affirmed the conviction of Joel Yatar for rape with homicide, emphasizing the admissibility and weight of DNA evidence in Philippine courts. The Court held that DNA evidence, when collected and analyzed properly, is a reliable and relevant tool for linking a suspect to a crime, even in the absence of eyewitnesses. This ruling marks a significant step in integrating scientific advancements into the Philippine criminal justice system, ensuring more accurate accounts of crimes, facilitating convictions of the guilty, and acquitting the innocent.

    Beyond Reasonable Doubt: How DNA Evidence Sealed a Conviction

    The case of Joel Yatar, accused of rape with homicide, hinged on the presentation and acceptance of DNA evidence. Kathylyn Uba was found dead in her grandmother’s house, the victim of a brutal crime. While circumstantial evidence pointed towards Yatar, it was the DNA analysis that solidified the case against him. Semen found in the victim’s vaginal canal was analyzed and found to be an identical match to Yatar’s DNA profile. The Supreme Court, in affirming the lower court’s decision, discussed the legal implications of admitting DNA evidence, setting a precedent for its use in future cases. This landmark decision navigates the complexities of forensic science and constitutional rights, aiming to integrate technological advancements into the pursuit of justice.

    The Court emphasized that the admissibility of DNA evidence is contingent upon its relevance and reliability, as established in Daubert v. Merrell Dow. Philippine law echoes this principle, requiring that evidence directly relate to a fact in issue, inducing belief in its existence or non-existence. The DNA evidence presented in the Yatar case, obtained through Polymerase Chain Reaction (PCR) testing and Short Tandem Repeat (STR) analysis, met these criteria. Moreover, the Court considered the qualifications of Dr. Maria Corazon Abogado de Ungria, the expert witness who conducted the DNA tests, and found her testimony credible and persuasive. Due diligence in the collection, handling, and analysis of samples is essential to ensure the integrity of DNA evidence. Contamination, improper standards, or unqualified analysts can undermine the reliability and admissibility of the results. Here, the established procedures and expertise bolstered the probative value of the DNA match.

    A critical challenge posed by the defense revolved around the constitutionality of obtaining blood samples for DNA testing. The appellant argued that this violated his right to remain silent and his right against self-incrimination. However, the Supreme Court clarified that the right against self-incrimination protects against testimonial compulsion, not the presentation of object evidence. Taking blood samples for DNA analysis does not compel an accused to testify against himself. Such procedures do not fall under the umbrella of testimonial compulsion. Furthermore, the Court cited existing jurisprudence affirming that a person may be compelled to submit to fingerprinting, photographing, or blood sampling, as these actions do not elicit communicative evidence under duress. This is a crucial distinction in understanding the limits of constitutional protections in the context of forensic investigation. Moreover, since the appellant voluntarily submitted himself for blood sampling during the trial in the presence of counsel, this act constituted a waiver of any potential objections to the procedure.

    The defense also argued that admitting DNA evidence constituted an ex post facto law, but the Court dismissed this contention. An ex post facto law retroactively criminalizes an act, aggravates a crime, or inflicts a greater punishment than the law annexed to the crime when committed. DNA profiling, on the other hand, involves assessing the admissibility, relevance, and reliability of scientific evidence under existing rules of procedure, making it distinct from an ex post facto application. The Court underscored that the probative weight of the evidence is subject to factual determination, consistent with the applicable Rules of Court.

    Independent of the DNA evidence, the trial court considered compelling circumstantial evidence to solidify the conviction. Witnesses placed Yatar at the scene of the crime around the time of the murder. The Court highlighted the following circumstantial evidence as critical to establishing guilt beyond a reasonable doubt:

    (1) Appellant and his wife were living in the house of Isabel Dawang together with the victim, Kathylyn Uba; (2) In June 1998, appellant’s wife left the house because of their frequent quarrels; (3) Appellant received from the victim, Kathylyn Uba, a letter from his estranged wife in the early morning on June 30, 1998; (4) Appellant was seen by Apolonia Wania and Beverly Denneng at 1:00 p.m. of June 30, 1998 near the kitchen of the house of Isabel Dawang, acting strangely and wearing a dirty white shirt with collar; (5) Judilyn Pas-a saw appellant going down the ladder of the house of Isabel at 12:30 p.m., wearing a dirty white shirt, and again at 1:30 p.m., this time wearing a black shirt; (6) Appellant hurriedly left when the husband of Judilyn Pas-a was approaching; (7) Salmalina Tandagan saw appellant in a dirty white shirt coming down the ladder of the house of Isabel on the day Kathylyn Uba was found dead; (8) The door leading to the second floor of the house of Isabel Dawang was tied by a rope; (9) The victim, Kathylyn Uba, lay naked in a pool of blood with her intestines protruding from her body on the second floor of the house of Isabel Dawang, with her stained pants, bra, underwear and shoes scattered along the periphery; (10) Laboratory examination revealed sperm in the victim’s vagina (Exhibit “H” and “J”); (11) The stained or dirty white shirt found in the crime scene was found to be positive with blood; (12) DNA of slide, Exhibit “J” and “H”, compared with the DNA profile of the appellant are identical; and (13) Appellant escaped two days after he was detained but was subsequently apprehended, such flight being indicative of guilt.

    Furthermore, evidence suggested a motive for the crime, as Judilyn Pas-a testified that the victim revealed a prior attempted rape by Yatar and that Yatar had threatened the victim’s family. Such statements are admissible as evidence of motive under Philippine law. These factors solidified the Court’s conviction beyond a reasonable doubt, affirming Yatar’s guilt for the special complex crime of rape with homicide.

    Ultimately, the Court slightly modified the lower court’s ruling on damages, increasing the civil indemnity to P100,000.00 and adjusting the actual and moral damages awarded. However, the sentence of death for the heinous crime was affirmed, underscoring the gravity of the offense and the importance of leveraging modern scientific advancements in the pursuit of justice. This ruling emphasizes the integration of forensic science in criminal investigations and the judiciary’s openness to leveraging technology for just outcomes.

    FAQs

  • DNA Evidence and Confessions: Convicting Without Eyewitnesses in Rape-Homicide Cases

    In the Philippines, a conviction for rape with homicide can be secured even without eyewitness testimony, provided that the prosecution presents sufficient circumstantial evidence to prove the accused’s guilt beyond a reasonable doubt. The Supreme Court, in People v. Vallejo, emphasized the importance of DNA evidence, the admissibility of voluntary confessions, and the evaluation of circumstantial evidence in such cases. This ruling reinforces the idea that justice can be served even when direct evidence is lacking, relying instead on a combination of forensic science and credible testimonies.

    Unraveling Justice: Can Wet Clothes and Unease Seal a Fate in a Rape-Homicide Case?

    The case of People of the Philippines v. Gerrico Vallejo revolves around the rape and murder of a 9-year-old child, Daisy Diolola, in Rosario, Cavite. The accused, Gerrico Vallejo, was convicted of rape with homicide based on circumstantial evidence, oral and written confessions, and DNA analysis. The central legal question was whether the totality of the evidence presented by the prosecution was sufficient to prove Vallejo’s guilt beyond a reasonable doubt, especially in the absence of direct eyewitness testimony.

    The prosecution built its case on several key pieces of circumstantial evidence. Firstly, witnesses testified that Vallejo was the last person seen with the victim before her disappearance. Jessiemin Mataverde stated that Daisy left with Vallejo towards the “compuerta.” Secondly, Charito Yepes and her husband saw Vallejo emerging from the area near the “compuerta” with wet clothes, appearing uneasy. The court also considered the recovery of bloodstained clothing from Vallejo’s residence and his initial false statement to the victim’s mother, Ma. Nida Diolola, about Daisy’s whereabouts.

    Building on this, the **DNA analysis** played a crucial role in linking Vallejo to the crime. Vaginal swabs taken from Daisy’s body contained DNA profiles matching both the victim and the accused. While the defense questioned the handling of other samples, the court found the DNA evidence from the vaginal swabs conclusive, significantly strengthening the prosecution’s case. The court addressed concerns about potential contamination of evidence, emphasizing that the negative results from some samples were due to the inadequacy of the specimens rather than flawed testing procedures.

    The admissibility of Vallejo’s **oral and written confessions** was another critical point of contention. The defense argued that the confessions were obtained through coercion and without proper legal counsel, violating Vallejo’s constitutional rights. However, the court found that Vallejo’s confessions to Mayor Abutan and NBI Forensic Biologist Buan were voluntary and spontaneous, not the result of interrogation by authorities. Moreover, the court determined that Atty. Lupo Leyva provided adequate legal assistance during Vallejo’s custodial investigation, ensuring that his constitutional rights were protected.

    The Supreme Court referenced Section 12 of Article III of the Constitution, which safeguards the rights of individuals under investigation. This section states that any person under investigation has the right to remain silent, to have competent legal counsel, and to be free from torture or coercion.

    “(1) Any person under investigation for the commission of an offense shall have the right to be informed of his right to remain silent and to have competent and independent counsel, preferably of his own choice. If the person cannot afford the services of counsel, he must be provided with one. These rights cannot be waived except in writing and in the presence of counsel.

    (2) No torture, force, violence, threat, intimidation, or any other means which vitiate the free will shall be used against him. Secret detention places, solitary, incommunicado, or other similar forms of detention are prohibited.

    (3) Any confession or admission obtained in violation of this or Section 17 shall be inadmissible in evidence against him.”

    The court emphasized that the constitutional procedures on custodial investigation do not apply to spontaneous statements, not elicited through questioning by the authorities, but given in an ordinary manner whereby the appellant orally admitted having committed the crime. The rights under Section 12 are guaranteed to preclude the slightest use of coercion by the state as would lead the accused to admit something false, not prevent him from freely and voluntarily telling the truth.

    Regarding the alleged maltreatment by the police, the court found Vallejo’s claims unsupported by evidence. Dr. Antonio Vertido’s physical examination revealed injuries inconsistent with Vallejo’s account of torture. The court applied the standing rule that bare assertions of maltreatment are insufficient without corroborating evidence, such as medical records or complaints filed against the alleged intimidators. Therefore, the court presumed Vallejo’s extrajudicial confessions to be voluntary.

    The defense of alibi presented by Vallejo was deemed weak and unconvincing. The court noted that alibi is the weakest of all defenses, especially when corroborated only by relatives or friends of the accused. Vallejo’s sister, Aimee Vallejo, corroborated his alibi, but the court found her testimony insufficient to outweigh the compelling circumstantial evidence presented by the prosecution. Thus, the Court ruled that when facts or circumstances which are proved are not only consistent with the guilt of the accused but also inconsistent with his innocence, such evidence, in its weight and probative force, may surpass direct evidence in its effect upon the court.
