Respondent/Accused-Appellant: Gerrico Vallejo y Samartino

• July 26, 1999 – Accused arraigned and pleads not guilty.
• July 31, 2000 – RTC, Branch 88, Cavite City, renders decision.

Applicable Law

1987 Philippine Constitution (Art. III, Sec. 12); Revised Penal Code, Article 266-B (Rape with Homicide) as amended by Republic Act No. 7659; Rules on Criminal Procedure and Evidence (Miranda‐type rights, circumstantial evidence under Rule 133).

Factual Background

On July 10, 1999, Daisy’s mother sent her to Aimee Vallejo’s house for lessons. At about 2 PM, Daisy and Gerrico left together to fetch a book, returned to Aimee’s house, and were last seen departing toward a riverside compuerta. That evening, Daisy failed to return despite an extensive search.

Discovery of the Body and Initial Identification

On the morning of July 11, fisherman Freddie Quinto discovered Daisy’s body tied to an aroma tree by the riverbank. At the barangay hall, Ma. Nida Diolola identified Gerrico Vallejo as the last person seen with the victim and as a suspect.

Circumstances of Last Sighting

Neighbors Jessiemin Mataverde and Charito Paras-Yepes observed Daisy playing outside, then saw her leave with accused. Paras-Yepes later saw Gerrico emerge from the compuerta with wet shorts and shirt, appearing pale and uneasy. Around 5 PM he purchased a cigarette; his clothes remained wet while hair and face were dry.

Forensic Evidence

Police recovered Gerrico’s white basketball shirt (No. 13) and violet shorts (No. 9), both bloodstained. Laboratory tests by Pet Byron Buan showed human blood Group A on both accused’s garments and the victim’s clothing; accused’s blood type was Group O. NBI DNA analysis on vaginal swabs found both the victim’s and accused’s DNA profiles.

Medical Findings

Dr. Vertido’s autopsy revealed multiple contusions, abrasions, lacerations consistent with a struggle, fresh hymenal lacerations, fractured tracheal rings, and internal hemorrhages. Cause of death was asphyxia by manual strangulation, confirming sexual assault and homicide.

Confession and Legal Counsel

Mayor Abutan interviewed the accused at the municipal jail; upon Gerrico’s admission of strangulation, the mayor secured the assistance of Atty. Lupo Leyva. Under counsel’s presence, accused signed a written extrajudicial confession. During NBI laboratory procedures, accused spontaneously admitted rape and killing to Biologist Buan, and later executed a second confession before Inquest Prosecutor Itoc with Atty. Sikat Agbunag present.

Defense’s Alibi and Torture Allegations

Accused and his sister Aimee testified he remained mostly at home, completed a drawing for Daisy, and only left to answer his mother. He alleged police beat, burned, and pricked him to force a confession. No objective proof of torture was presented; physical injuries noted by Dr. Vertido were abrasions and hematomas consistent with a struggle bite, not systematic torture.

Trial Court Verdict

The Regional Trial Court found Gerrico Vallejo guilty beyond reasonable doubt of rape with homicide, sentenced him to death, and awarded P100,000 civil indemnity and P50,000 moral damages to the victim’s heirs.

Issues on Appeal

I. Sufficiency and weight of circumstantial evidence.
II. Admissibility of alleged oral confessions as hearsay.
III. Validity of the extrajudicial written confession given purportedly under force and without effective counsel.

Supreme Court’s Analysis on Circumstantial Evidence

Under Rule 133, sec. 4, multiple proven circumstances combined must yield moral certainty. The sequence of last
