Police said officers responding to a report of a shooting at the condominium complex found a critically injured Pham lying on a bedroom floor. He was pronounced dead a short time later.
The victim's son -- identified as the suspected shooter -- was not found in the house following shooting. He was taken into custody in the early morning hours of April 30 after a witness spotted him walking in the 10100 block of Scripps Poway Parkway, several miles from where the shooting took place.
At the time of his arrest, the teen was carrying a handgun and several rounds of ammunition, according to police.
The boy is scheduled to return to Juvenile Court on May 18 for a readiness hearing.
