Case Summary (G.R. No. 130331)
Procedural Posture and Key Dates
Crime occurred the evening of January 3, 1995; corpse discovered January 4, 1995. Informations were filed May 18, 1995 (Criminal Case Nos. 95-1609(M) and 95-1610(M)). Adel was arraigned June 5, 1995; Sonny was later apprehended and arraigned; Nelson remained at large. Trial testimony took place between 1995 and 1996. Judgment below convicted Adel and Sonny; the case proceeded to the Supreme Court on automatic review, culminating in the decision affirmed by the Court (per curiam) on November 22, 2000. Because the decision date is after 1990, the 1987 Philippine Constitution provided the constitutional framework for the review.
Charges and Applicable Law
Two informations: (1) Criminal Case No. 95-1609(M) — theft (alleged taking of watch, rings, earrings, P3,000 cash, camera); (2) Criminal Case No. 95-1610(M) — rape with homicide (rape committed with homicide, with aggravating circumstances alleged: evident premeditation, abuse of superior strength and nighttime). The rape-with-homicide count was prosecuted under Article 335 of the Revised Penal Code as amended, including Republic Act No. 7659 (which prescribes the death penalty for rape with homicide); other statutory references and procedural rules (e.g., competence of witnesses under Rule 130, Sec. 20, Revised Rules of Court) were invoked in the proceedings.
Trial Evidence and Factual Narrative
The prosecution’s principal eyewitness, Silvestre Sanggalan, testified that he and the three accused were drinking earlier that evening at a “beer house,” later proceeding to a waiting shed near the highway. When Aurea Eugenio walked toward her house, Adel, Sonny (identified later as “Baba”), and Nelson (alias “Tatoo”) followed her into the rice field. Sanggalan testified that the three assailants attacked Aurea: one pushed her, Adel grabbed her shoulder bag, and the other two pushed her against a tree and stabbed her. The three then allegedly stabbed her neck repeatedly until she fell; a bottle (Pidol cough syrup) was inserted into her vagina and pushed; the three removed the victim’s clothing and successively raped her while she resisted; after the assault, the assailants took various personal effects and fled in different directions. Sanggalan said he observed these events from approximately three and one-half meters away, hid rather than leave when ordered, and later identified Adel and Sonny in court photographs and in person.
Medical and Forensic Evidence
Dr. Dominic Aguda’s autopsy established multiple serious injuries: several gaping stab wounds to the neck (nine wounds described, involving skin, blood vessels, throat, trachea and esophagus) causing massive hemorrhage and severe blood loss (proximate cause of death), pallor of visceral organs, and external abrasions/hematomas consistent with struggle. Genital findings included fresh lacerations on the hymen, a V-shaped median perineal laceration, and massive blood clots in the vaginal canal; the doctor opined these injuries were consistent with penile penetration and the insertion of a hard foreign object (e.g., a bottle). The medical evidence corroborated sexual assault and the violent nature of the attack leading to death.
Defense Case and Impeachment Attempts
Both accused pleaded not guilty and presented alibi evidence. Adel testified he was at home that evening; his common-law wife (Liza Reyes), mother (Erlinda Tuangco), and sister (Glessen) corroborated his alibi. Sonny testified he was alone at his house in Balungao, Calumpit, Bulacan. The defense sought to impeach Sanggalan’s credibility by presenting testimony and documentary evidence to show he was a drunkard, a drug user, and that a rape case was pending against him; they also attacked the manner of his testimony on account of his deaf-muteness and lack of formal education in a school for the deaf.
Trial Court Findings and Verdict
The trial court found the prosecution established guilt beyond reasonable doubt. It credited Sanggalan’s eyewitness testimony, found the three accused conspired to commit the crimes, and concluded that Adel and Sonny were principals in both theft and rape with homicide. Sentences pronounced: for theft (Crim. Case No. 95-1609) indeterminate penalty from six months arresto mayor to two years, eleven months and ten days prision correccional, plus indemnity; for rape with homicide (Crim. Case No. 95-1610) the court sentenced each accused to two death penalties (reflecting two special complex crimes of rape with homicide), and ordered civil indemnities, moral and exemplary damages. The trial court found aggravating circumstances (e.g., evident premeditation, abuse of superior strength, and deliberate use of nighttime).
Issues on Appeal to the Supreme Court
The appellants raised two principal assignments of error: (1) the trial court erred in giving full faith and credence to the testimony of the deaf-mute eyewitness, Silvestre Sanggalan, who lacked formal schooling for the deaf and whose testimony allegedly contained inconsistencies; and (2) the trial court erred in finding both accused guilty beyond reasonable doubt of the two counts of the special complex crime of rape with homicide and theft.
Supreme Court Analysis on Competence and Credibility of Deaf‑Mute Witness
The Court reaffirmed the competence of deaf-mute witnesses provided three conditions are satisfied: (1) the witness can understand and appreciate the sanctity of an oath, (2) the witness comprehends the facts to which he will testify, and (3) the witness can communicate his ideas through a qualified interpreter. The Court emphasized that minor inconsistencies in testimony tend to indicate veracity rather than rehearsed fabrication and are insufficient to render testimony incredible. The interpreter used by the prosecution, Eva Sangco, was found qualified: she had long teaching experience at the Philippine School for the Deaf, prior court interpreting experience, and specialized training in the “natural homemade sign” method used to interpret Sanggalan’s testimony. The Court reviewed relevant precedents (People v. Hayag; People v. De Leon; People v. Sasota; People v. Bustos; People v. Dominguez; People v. Tanco) and concluded that the imperfections cited by defense arose from the inherent difficulties in eliciting testimony from a deaf‑mute, not from mendacity. The trial court had appropriately evaluated the interpreter’s competence and Sanggalan’s demeanor and credibility; the Supreme Court accorded due respect to those factual assessments.
Corroboration, Conspiracy Finding, and Weight of the Evidence
The Court noted that Sanggalan’s testimony was materially corroborated by the autopsy findings showing sexual assault and violent stabbing, as well as by circumstantial facts (proximity of the accused to the scene, their joint drinking and movement from the beerhouse to the waiting shed, their simultaneous pursuit of the victim, a

Arraignment, Pleas, and Status of Accused
- Adel Tuangco was arraigned on June 5, 1995 and pleaded not guilty to both charges.
- During trial, Sonny Tuangco was apprehended and pleaded not guilty; he had at some point gone into hiding after Adel’s arrest and stayed with a relative in Caloocan City for about one year until apprehension.
- Nelson Pineda, Jr. (alias “Jun Tattoo”) remained at large throughout the trial.
Principal Prosecution Evidence — Eyewitness Testimony (Silvestre Sanggalan)
- Main eyewitness: Silvestre Sanggalan, described as a deaf-mute; he testified through sign language interpreted by a sign language expert (Eva Sangco).
- Sanggalan’s account (trial court’s summation of his testimony):
- He had been at a “beer house” along the national highway around 6:00 p.m. with seven companions, including the three accused.
- When night fell, Sanggalan and three companions left and proceeded to a rice field near the highway and stayed in a waiting shed because they were drunk.
- The three companions with him in the waiting shed were identified as: (a) a tricycle driver with tattoos and scars (“Tatoo”/Nelson Pineda, Jr.), (b) a person with a long chin known as “Baba” (identified later as Sonny Tuangco), and (c) Adel Tuangco.
- The three accused left the waiting shed to follow and catch up with a girl wearing long hair — identified in court from photographs as Aurea Eugenio.
- Upon catching up, “Tatoo” pushed her; Adel grabbed her shoulder bag; “Baba” and “Tatoo” pushed her against a tree and stabbed her repeatedly in the neck; Adel joined and also stabbed the deceased.
- After she fell, “Tatoo” inserted a bottle of Pidol cough syrup into her private parts; “Baba” pushed it further while Adel hugged and restrained her; the three removed her clothes and successively raped her (Adel first, then “Tatoo,” then “Baba”), with the other two holding her hands when one raped her.
- Adel took her bag; “Tatoo” took her camera and cash; “Baba” took her ring, earrings, and watch; thereafter “Tatoo” and “Baba” went into the rice field and Adel went the other direction.
- During the assault Sanggalan was approximately three and one-half (3½) meters away and on two occasions was asked to leave but hid instead; he later identified “Baba” as Sonny Tuangco when recalled on January 17, 1996.
- The trial court found Sanggalan’s testimony candid, straightforward, and credible; the court noted that minor inconsistencies did not render him incredible and in fact may indicate non-rehearsed testimony.
Sign Language Interpreter and Competence
- Interpreter: Eva Sangco, described as a certified sign language interpreter with 22 years’ teaching experience at the Philippine School for the Deaf, exposure in television programs, and prior testimony in five court proceedings.
- Interpretation method used: the natural or homemade sign method; the interpreter explained several modes of communication for deaf-mute interpretation (oral method, simultaneous, pantomime, reverse interpretation, speech reading, natural signs and gestures, interactive writings, dramatization and drawing).
- The trial court evaluated and found the interpreter’s qualifications sufficient to accurately put Sanggalan’s declarations on record.
- The Supreme Court emphasized that while examination of a deaf-mute is regulated by the trial court’s discretion, the method used will not be overturned absent a showing the complaining party was injured by the method.
Forensic and Medical Evidence (Dr. Dominic Aguda)
- Autopsy findings by Dr. Dominic Aguda, medico-legal officer at the NBI:
- Multiple hematomas (left frontal region, right frontal region, right auricular region, palms, chest, chin, breasts) and abrasions and lacerated wounds in various locations (pre-auricular, chin, breasts).
- Stab wounds: nine (9) stab wounds described — six (6) on the left side of the neck (gaping, 9.0 x 6.0 cms area, depths 2–5 cms, involving skin, blood vessels, lacerating throat and esophagus) and three (3) on the right side of the neck (gaping, 6.0 x 5.0 cms area, depths about 2.4 cms, involving skin, blood vessels, hitting trachea).
- Brain and visceral organs very pale; heart chambers contained a very small amount of dark clotted blood; stomach empty.
- Genital findings: fresh lacerations on the hymen on all sides with an opening of about 4.0 x 3.0 cms; massive blood clots within the vaginal canal; a V-shaped median laceration of the perineum about 5.0 cms.
- Dr. Aguda’s interpretation: the fresh hymenal lacerations and massive blood clots were caused not only by penile penetration but also by a hard foreign object such as a bottle; abrasions on the breasts could have been caused by human bites; stab wounds were inflicted by a single-bladed weapon; proximate cause of death was severe hemorrhage secondary to multiple stab wounds; abrasions and hematomas indicated struggling during sexual attack.
- The autopsy corroborated Sanggalan’s account of rape with insertion of a bottle and multiple stab wounds leading to death.
