SAN DIEGO — Two people were fatally shot at a home in Point Loma early Friday, and the alleged gunman was arrested after law enforcement spent hours searching for him, police said.

The suspect is a 22-year-old male who neighbors believe is the victims’ son, Peter Haynes.

Officers responded to a report of gunfire in the 1000 block of Tarento Drive at 3:11 a.m., according to San Diego police.  A police dispatcher heard gunshots as the man asked for help shortly before the phone disconnected, San Diego police homicide Lt. Paul Rorrison said.

“I thought it was firecrackers at first,” said neighbor Trisha Adams. “I actually called their house just to say, ‘Hey I’m watching out for you.’ I had no idea what was happening there. There was no one there.”

The victims were rushed to UCSD Medical Center where both were later pronounced dead.

“Hard working daddy, doctor…bad things happen to good people,” said Adams.

Police, including SWAT members and K-9 units, searched for the alleged gunman at a nearby park and in the home where the shooting occurred.

Around 7 a.m. police made an arrest as the suspect tried to slip back toward the area. The 22-year-old suspect had a handgun in his pocket during the time of the arrest, according to police.

“There was like five cops on top of him…he was sitting in the back of the police car and he was totally calm, like nothing,” said neighbor John Rickards.

Neighbors who knew the victim’s family said this is something they never saw coming.

“Nobody that knows them would say, ‘Oh, that doesn’t surprise me.’ I’ve read about that stuff — but no way,” said Adams.

Police are still on scene continuing their investigation. They do not have any information yet regarding a possible motive.

Rorrison said the identities of the victims were known, but were being withheld until family members could be notified.

He asked anyone with additional information on the shootings to call police at 619-531-2425, or Crime Stoppers at 888-580-8477.
