SAN DIEGO (AP) - Officials say a New Year's Day shooting that left four people dead at a condominium near San Diego was a murder-suicide involving a 25-year-old Navy pilot who killed himself.

The San Diego County Sheriff's Department - citing autopsy results - says John Robert Reeves, of Prince Frederick, Md., shot himself in the head, and the three others with him were murdered.

Fellow Navy pilot David Reis, also 25, was killed by a gunshot wound to the torso and his 24-year-old sister, Karen, suffered a gunshot wound to the head and chest, officials said.

A 31-year-old Chula Vista man, Matthew Saturley, was shot multiple times.

Officials previously said that one of the men was found dead in the doorway of the three-story condo and the bodies of two men and a woman were inside the home.
