Case Summary (G.R. No. 236726)

Procedural History

An Information charged Calimutan with homicide for allegedly throwing a fist-sized stone that struck Cantre in the back resulting in a lacerated spleen and death. Warrant of arrest issued; petitioner posted bail and pleaded not guilty. Trial court (RTC, Branch 46, Masbate) convicted Calimutan of homicide and imposed penalty and damages. The Court of Appeals affirmed that conviction. Petitioner sought review before the Supreme Court by way of a Petition for Review on Certiorari under Rule 45.

Factual Findings Established at Trial

Eyewitness testimony established that on 4 February 1996 Cantre, after a drinking spree, confronted and struck Michael Bulalacao. Calimutan and Bulalacao were present; Bulalacao fled and Calimutan reportedly ran up behind Cantre and threw a stone which struck the left posterior chest/back of Cantre. Cantre thereafter complained of back and abdominal pain, his condition deteriorated, and he died in the early hours of 5 February 1996. No other intervening blunt trauma was identified between the stoning incident and Cantre’s death.

Medical Evidence and Autopsy Findings

The Municipal Health Officer, Dr. Ulanday, performed an initial, limited post-mortem examination and issued a certification suggesting suspected food poisoning as an antecedent but did not perform an exhaustive internal autopsy and expressly recommended laboratory confirmation. The body was embalmed and buried. The family later requested exhumation and the NBI autopsy was performed by Dr. Mendez (15 April 1996). Dr. Mendez’s autopsy found contused-abrasion on the posterior chest wall, a large abdominal hematoma, massive hemoperitoneum with clotted blood, and a lacerated spleen. He concluded cause of death was traumatic injury of the abdomen due to splenic laceration, consistent with blunt force such as a stone. Dr. Mendez testified as an expert at trial; his qualifications were admitted.

Defense Account

Petitioner Calimutan testified that he acted to protect Bulalacao, who had been punched by Cantre and—according to Calimutan—threatened trouble with a knife (a claim the Supreme Court regards as unsupported and dismissed). Calimutan claimed he impulsively threw a small stone (described at trial as approximately one inch in diameter) from about ten meters away and hit Cantre on the right buttock; he denied intent to kill and denied knowledge of subsequent events, accepting that Cantre later died, which Calimutan attributed (per his understanding) to food poisoning.

RTC and Court of Appeals Rulings

The RTC concluded that the throwing of the stone was a retaliatory and unlawful act amounting to homicide under Article 249 of the Revised Penal Code, reasoning that the aggression had ceased when Bulalacao ran away and that the act exhibited treachery. The RTC sentenced Calimutan to imprisonment and awarded compensatory and moral damages. The Court of Appeals affirmed, giving great weight to Dr. Mendez’s autopsy and testimony, rejecting Dr. Ulanday’s unsupported suspicion of food poisoning because she was not presented for cross-examination, and finding proximate causation between the stone and the splenic laceration leading to death.

Issue(s) on Appeal to the Supreme Court

The primary contentions included: whether the prosecution established beyond reasonable doubt that the stone thrown by Calimutan caused Cantre’s death; and whether the existence of two government physicians’ reports with differing conclusions (Dr. Ulanday’s suspicion of food poisoning and Dr. Mendez’s autopsy finding of traumatic splenic laceration) created reasonable doubt. Additionally, whether the correct characterization of the offense was homicide (intentional) or a lesser culpable felony such as reckless imprudence resulting in homicide.

Standard of Proof and Evidentiary Principles Applied

The Court reiterated that criminal conviction requires proof beyond reasonable doubt (Rule 133 standard). Expert testimony is admissible and entitled to weight when the witness is qualified and the testimony is consistent and based on a proper examination. The Court also noted that the prosecution is not required to present all possible corroborative witnesses, and failure to present a listed witness does not automatically establish suppression of evidence if non-presentation is not willful, the evidence is cumulative, or available to both parties.

Supreme Court’s Evaluation of Causation and Credibility of Medical Evidence

The Supreme Court found that Dr. Mendez’s exhaustive autopsy and consistent expert testimony established that Cantre died of massive internal hemorrhage from a lacerated spleen and that such an injury is consistent with blunt-trauma impact from a stone. The Court explained that splenic rupture can occur from blunt force applied to the abdominal region and that such internal injuries may present with minimal or no external signs. The presence of a contused-abrasion on the left posterior chest wall, the large hematoma, massive hemoperitoneum, and direct autopsy observation supported the causal link between the stone strike and the splenic laceration. The Court gave greater probative weight to the NBI autopsy than to Dr. Ulanday’s limited examination and mere suspicion of food poisoning, especially since Dr. Ulanday had not performed an exhaustive autopsy, recommended confirmatory laboratory tests that were not shown to have been done, and was not presented for cross-examination at trial.

On the Two Medical Opinions and Claim of Reasonable Doubt

The Supreme Court rejected the defense’s contention that the divergent initial certification created reasonable doubt. It reasoned that the differences were explicable by the disparity in the scope of examinations—Dr. Ulanday’s limited, non-exhaustive exploration versus Dr. Mendez’s full internal autopsy after exhumation. Dr. Ulanday herself had described her finding as a mere suspicion and had not opened the body cavity for a full internal inspection. Consequently, the NBI autopsy, corroborated by eyewitness testimony linking the stone impact to subsequent symptoms and deterioration, removed the reasonable doubt asserted by the defense.

Reclassification of Offense: Homicide versus Reckless Imprudence Resulting in Homicide

Although the Court agreed with lower courts that the stone thrown by Calimutan was the proximate cause of Cantre’s death, the Supreme Court disagreed with convicting Calimutan of the intentional crime of homicide under Article 249. Applying the statutory distinction in Article 3 of the Revised Penal Code between intentional felonies (malicious, deliberate intent) and culpable felonies (resulting from imprudence, negligence, or lack of skill), the Court found absence of malice or deliberate intent to kill. The Court emphasized circumstances indicating spontaneity and lack of
