SAN DIEGO — Police are searching for a man involved in a shooting at a Halloween party that left one person seriously hurt in Pacific Beach.

Officers were called around 3:45 a.m. Monday to an area near 3800 Jewell Street, a few blocks from Crown Point Park. San Diego police say a Halloween party was underway at an apartment complex when a fight broke out, which led to the shooting.

“It sounds like a melee started inside this party, so multiple people fighting,” an SDPD spokesperson said. “At some point, the suspect decided during the fight that he’d pull out a handgun and shoot the victim.”

Officers said they found a man shot in the upper part of his body on the ground at the end of a hallway in the G building of the apartment complex. First responders said the unidentified man was expected to survive despite being taken to the hospital with life-threatening injuries.

Trinity McClanghan, 18, said she was part of the initial fight at the party. She said there were about 30 people inside the apartment when someone accused her of assaulting their boyfriend.

“I don’t recall hitting nobody,” McClanghan said. “But she wanted to fight me.”

McClanghan said she ended up crouched on the floor, unable to fight back as she was being punched.

Outside the complex, dozens of patrol cars blocked the street as partygoers ran from the apartment. Police detained several people for questioning, including McClanghan.

“I got up and then I was hearing the cops pull up and I was walking down the street and they stopped me,” she said, adding that she was taken to the hospital via ambulance then released. 

Residents at AVA Pacific Beach apartments who did not want to go on camera Monday said the apartment where the shooting happened is no stranger to police. They claimed parties go on almost every night.

Police are still searching for a suspect in Monday’s shooting. He was described as a 5-foot 8-inch black man who was wearing a beanie and yellow jersey at the time. Anyone with information was asked to call police or Crime Stoppers.
