MANILA - The Court of Appeals affirmed the murder conviction of Jason Ivler, who shot the son of a former Malacanang official in a traffic altercation 8 years ago, according to a copy of the decision.

The CA rejected Ivler's appeal to overturn the 2015 decision of a Quezon City court, which sentenced him to reclusion perpetua or a minimum jail term of 30 years for the killing of Renato Ebarle Jr.

The court said Ivler "treacherously shot" Ebarle, while the victim was waiting out the red light in his car.

"He (Ebarle) was unarmed and was not given any opportunity to defend himself or to escape from the deadly assault," the decision read.

Ivler, nephew of singer Freddie Aguilar, shot Ebarle during a traffic argument in Santolan, Quezon City on November 18, 2009. Ebarle succumbed to 3 gunshot wounds.

Ivler, an aspiring rapper, did not surrender to authorities and was captured at his family's residence.
