G.R. No. 133737 - People vs. Diaz

Case Summary (G.R. No. 133737)

Factual Background: Events of October 14, 1995

At about 11:00 o’clock in the morning of October 14, 1995, three female students—Deborah Comille, Maria Coleen Lincoln, and Janet Nalzaro—met outside the school library and proceeded toward the faculty room on the second floor of the Gonzaga wing of the Ateneo de Zamboanga, passing back stairs near the backfield of the campus. As they approached the corridor leading to the faculty room, they heard the scream of a woman. They later heard another scream and struggling emanating from the men’s comfort room. Although they initially thought it might be a “lovers quarrel,” Janet Nalzaro and Maria Coleen Lincoln refrained from entering because it was a men’s comfort room. Janet sought attention from an adjacent male teacher but was not noticed, prompting Deborah Comille to call for help from inside the faculty room.

Miss Evelyn Garcia, a faculty member, went toward the men’s comfort room but hesitated, then returned to seek assistance from male faculty member Servando Halili. Halili responded and inspected the comfort room. He first checked the urinals and found none, then Cubicle No. 1, which was empty. When he reached Cubicle No. 2 and started moving toward Cubicle No. 3, he saw the back of a big male person wearing a white T-shirt and maong pants inside, and the door of Cubicle No. 2 slammed shut.

Halili then sought assistance from higher authorities, while posting himself on the corridor about four or five meters from the men’s comfort room door. Garcia went downstairs to the office of Assistant Dean Aldrin Hitalia. Halili was later called by Garcia, who reported that the dean was not in her office. At that moment, Halili turned toward the comfort room and saw a tall man with broad shoulders wearing a white T-shirt and maong pants emerge from the men’s comfort room. The man was wiping his face with a piece of cloth and carrying a bag. Deborah Comille saw him fully enough to recognize his face later as Jonathan Diaz, describing that he came out with a towel to wipe his face and that she recognized him as a classmate from the second semester of school year 1993–1994. Lincoln and Jocelyn Partosa likewise witnessed a tall, big man in similar clothing, partially covering his face with cloth, coming out of the comfort room.

As the man hurried down the corridor toward the back stairs, he uttered the words “Papatayin kita.” He then rushed down the back stairs and met Garcia, who, though frightened, noticed he looked familiar due to having seen him in campus. Garcia observed he was sweating and that there was a red spot at the left chest of his shirt.

After the man left, the group entered the men’s comfort room and discovered the victim, Christie Joy Torres, lying unconscious in Cubicle No. 2, the same cubicle where Halili had previously seen the big male person. The victim was carried to the school infirmary for first aid. Ceferina Gonzales recognized the victim earlier that morning as the girl she saw talking to a tall and big man in white T-shirt and maong pants in front of the comfort room corridor.

The victim was then taken by school vehicle to Zamboanga Doctors Hospital, where she was declared DOA by Dr. Concepcion Fabian. She suffered injuries including multiple stabbed wounds in vital parts of her body. A post-mortem examination conducted later that afternoon by Dr. Henry Cawley, medico-legal officer of the NBI Regional Office in Zamboanga City, verified the fatal injuries.

Meanwhile, after the victim’s death, an emergency meeting was held in the Office of the Dean at the Ateneo de Zamboanga. Pictures of students and former students were produced and shown to possible witnesses. Comille identified Jonathan Diaz first through his picture.

Prosecution Evidence Linking Diaz to the Scene

The prosecution established that Diaz entered the Ateneo de Zamboanga campus through Gate II at 9:20 in the morning. This was testified to by Lorna A. Natividad, a security guard of the Black Arrow Security Agency, who said Diaz, whom she knew as a former student, arrived at Gate II and asked to enter.

The prosecution further placed Diaz near the men’s comfort room area. Isidro Francisco, the janitor, testified that at about 10:00 Diaz was standing on the ground floor near the comfort room and conversed with him. Arnold Toribio, a school nurse, testified that around 10:50, he met Diaz on the way to the canteen behind the school gymnasium. Toribio knew Diaz from school and nodded at him. Toribio observed Diaz wearing a white T-shirt and saw something clinging at his left shoulder, along with perspiration on Diaz’s head. Toribio claimed certainty of time because he checked the clock before leaving the infirmary.

The prosecution also introduced a witness (rebuttal) to counter the defense claim that the adjacent classroom did not hear the victim’s screams. It also established that after authorities regarded Diaz as a suspect, Diaz disappeared and could not be located at his parents’ residence in Guiwan, Zamboanga City, nor in Isabela, Basilan where his family resided. He was later found and arrested by PARAC agents in Silang, Cavite on August 17, 1996, about ten months after the incident.

Defense Theory and Evidence

Diaz contested the prosecution’s case on the basis of identification and the reliability of the circumstantial chain. He argued that no prosecution witness saw him on the second floor before the victim was discovered unconscious, and that even if he had been inside, there was no assurance that there was no other person who could have been the assailant. He also questioned why the adjacent classroom occupants allegedly did not hear the screams.

The defense presented Dr. Rodolfo Valmoria, who testified that, considering the victim’s wounds in the scapular region and contusions in the neck, it was doubtful whether the victim could have still talked or made any sound, contrary to the students’ accounts. Dr. Indah Taas Alpa, an expert in psychiatry, testified about the accused’s tendency to escape and isolate himself because people were trying to arrest him. Diaz also offered testimony from his relatives and acquaintances regarding his movements on October 14, 1995 and later days.

Diaz testified in detail, asserting that he went to Ateneo de Zamboanga to look for his brother-in-law, entered using Gate II, talked with Jose Neil Nave on campus, and left through Gate I. He also stated that after leaving Ateneo, he encountered Editha Aquino, boarded a tricycle, attempted to contact people to fetch time and schedules, and later drank with friends in Cavite. He claimed that after he learned that his name was mentioned as a suspect in the stabbing incident, he tried to avoid capture, moved from place to place, eventually boarded a vessel for Manila, and later worked in Laguna and Cavite. He claimed his arrest followed on August 17, 1996 while he was being hunted.

Issues Raised on Appeal

Diaz assigned errors contending that the RTC: (1) erred in convicting him based solely on circumstantial evidence; (2) erred in holding that motive was not essential; and (3) erred in treating flight as an admission of guilt. The appellate court framed the appeal around three issues: the sufficiency of circumstantial evidence; whether motive is essential when conviction rests on circumstantial evidence; and whether flight constitutes an admission of guilt or otherwise evidences culpability.

The Court’s Ruling on the Sufficiency of Circumstantial Evidence

The Court held that while no witness actually saw Diaz stab the victim, the circumstantial evidence was sufficiently strong to establish guilt beyond reasonable doubt. It applied the doctrine that direct evidence of killing is not indispensable when circumstantial evidence can form an unbroken chain of events leading to one fair and reasonable conclusion pointing to the accused to the exclusion of all others. The Court restated that circumstantial evidence is sufficient when there is more than one circumstance, the facts from which inferences are derived are proven, and the combination of circumstances produces guilt beyond reasonable doubt.

The Court found the RTC’s reconstruction persuasive and treated it as a structured chain. The circumstances were: Diaz entered through Gate II at 9:20 a.m.; he was seen near the comfort room area at about 10:00 a.m.; Halili responded to screams from the men’s comfort room, saw a big male figure in Cubicle No. 2, and later saw Diaz emerge as the door and Halili’s waiting position aligned with the timing of the victim’s presence; three witnesses—Comille, Lincoln, and Partosa—saw the big and tall man come out and described enough familiarity to recognize Diaz once the cloth was no longer covering the face; Garcia also saw the man descending the back stairs, recognized him from campus familiarity, and noticed sweating and a red spot near the left chest area; an additional witness heard the screams and banging of a door at the relevant time; at around 10:50, Toribio met Diaz and observed a white T-shirt with something clinging and perspiration; and after the incident, Diaz disappeared for nearly ten months and was arrested only on August 17, 1996.

The Court concluded that there was no showing of improper motives behind the witnesses’ identification, and it emphasized the trial court’s superior position to assess credibility. It sustained the findings absent a clear showing of overlooked facts or misappreciation of material circumstances.

Motive Not Essential Once Identity and Participation Were Established

On motive, Diaz argued that where identity rested on circumstantial evidence, motive must be shown, citing People vs. Peruelo. The Court rejected this approach. It relied on its ruling in People vs. Rendaje, explaining that once the prosecution established guilt beyond reasonable doubt and pinpointed the accused as the perpetrator to the exclusion of all others, motive becomes not essential. The Court also invoked People vs.

Case Syllabus (G.R. No. 133737)

The appeal assailed the Decision dated March 6, 1998 of the Regional Trial Court of Zamboanga City (Branch 13) which found Jonathan Diaz guilty of murder.
The trial court sentenced Diaz to reclusion perpetua and ordered him to pay the heirs of Christie Joy Torres civil indemnity, actual damages, moral damages, and costs.
On arraignment, Diaz pleaded not guilty to the Amended Information dated August 26, 1996 charging murder committed on or about October 14, 1995 in Zamboanga City, with qualifying circumstances alleged as treachery, evident premeditation, abuse of superior strength, and disregard of respect due the offended party on account of her sex, and with use of a bladed weapon.
The prosecution presented eighteen witnesses, and on rebuttal it presented additional witnesses, including Police Inspector Francisco Carpio de los Reyes, Rodolfo Torres, and NBI Special Investigator Pablo Acosta, Jr.
The Court framed three issues for resolution: the sufficiency of circumstantial evidence for conviction, the relevance of motive in a circumstantial-evidence case, and whether flight amounted to an admission of guilt.

Material Facts of the Killing

The Court accepted the trial court’s narrated sequence of events in and around the male comfort room on the second floor of the Ateneo de Zamboanga college building, Gonzaga wing, on October 14, 1995.
Three friends, namely Deborah Comille, Maria Coleen Lincoln, and Janet Nalzaro, proceeded from the school library to the faculty room on the second floor and heard a woman’s scream.
When another scream and struggling were heard from inside the male comfort room, the girls initially considered the possibility of a “lovers quarrel,” but later sought assistance.
Deborah Comille called for help from the faculty room, and Evelyn Garcia went toward the male comfort room but hesitated, then sought help from Servando Halili, Jr.
Servando Halili checked the urinals and found them empty, checked Cubicle No. 1 and found it empty, but upon approaching Cubicle No. 2, he saw the back of a big male person in a white T-shirt and maong pants while the door of Cubicle No. 2 was slammed shut.
After seeking higher authority, Halili waited outside the comfort room corridor area with others, including Janet Nalzaro, Maria Coleen Lincoln, Deborah Comille, Shalimar Alih, and Jocelyn Partosa.
When Assistant Dean Aldrin Hitalia was not found in the office, Halili turned back and saw a tall and broad-shouldered man in a white T-shirt and maong pants emerge from the comfort room, partially wiping his face with cloth and carrying a bag.
Witnesses described the man’s actions as hurriedly passing down the corridor and down the back stairs, and Deborah Comille later identified him as Jonathan Diaz based on her recognition of his face.
As the man passed Servando Halili, he uttered the words “Papatayin kita.”
Evelyn Garcia confronted the same man at the back stairs, noticing his familiar appearance, perspiration, and a red spot near the left chest area of his T-shirt.
After the man left, those present entered the male comfort room and discovered Christie Joy Torres lying unconscious in Cubicle No. 2, the same cubicle where Halili previously saw the back of the big male person before the door was slammed shut.
School personnel brought Torres to the infirmary for first aid, and she was later transported to the Zamboanga Doctors Hospital, where she was declared DOA by Dr. Concepcion Fabian.
The medico-legal examination conducted by Dr. Henry Cawley verified that Torres died from multiple stab wounds in vital parts of her body, as established through autopsy findings.
The identification process included recognition by witnesses from the scene and later picture identification in the dean’s office, where the accused’s picture was selected as the person who emerged from the comfort room immediately before discovery of the victim.

Evidence Linking Diaz to the Scene

The prosecution established that Diaz entered the Ateneo de Zamboanga campus through Gate II at 9:20 in the morning, as testified by Lorna A. Natividad, a security guard.
The prosecution presented Isidro Francisco, who testified that at about 10:00 in the morning, Diaz was standing at the ground floor near the male comfort room area and conversed with him.
The prosecution established that moments after 10:50 in the morning, the accused passed by Arnold Toribio, who testified that Diaz appeared in a white T-shirt with something clinging to his left shoulder and that Diaz nodded to Toribio.
The prosecution relied on witness descriptions of the man emerging from the comfort room as tall, broad-shouldered, wearing a white T-shirt and maong pants, carrying a bag, wiping his face with cloth, and displaying physical indications such as perspiration and a red spot on the T-shirt.
The Court treated the sightings and identifications as forming a continuous and coherent chain of circumstances from Diaz’s presence in the campus to his emergence from the comfort room and the immediate discovery of the injured victim.

Appellant’s Defense Theory

The defense presented medical testimony to challenge the possibility that the victim’s condition allowed her to scream, particularly through Dr. Rodolfo Valmoria, who questioned whether the victim could have still talked or made any sound given injuries.
The defense presented psychiatric expert testimony from Dr. Indah Taas Alpa to explain a tendency of an accused to escape and isolate himself because people were trying to arrest him.
Sergio Jose Andante Dayrit, the brother-in-law of Diaz, testified that he saw Diaz in the Ateneo premises at about 10:35 in the morning and that they conversed for five to ten minutes near Gate II.
Editha Aquino, a former student, testified that on the morning of October 14, 1995, she saw Diaz pass by while waiting near an electric post outside the campus, and she described his clothing as a light gray shirt and cream denim pants.
Gloria Diaz, Diaz’s mother, testified that Diaz had no prior record of law-breaking in school or outside.
Jose Neil Nave testified that Diaz talked with him around 9:30 in the morning, helped locate Nave’s brother-in-law around late morning, reminded Nave of an afternoon birthday party, and later left through Gate I around
