Homicide detectives responded to the 4200 block of Via Marina Court (map) after the man’s body was found at 3:26 a.m., according to a sheriff’s news release.

Police taped off the parking lot of the Shores apartment complex, where the body was discovered.

The victim, who was unarmed according to authorities, was pronounced dead at the scene.

He was identified as 47-year-old Patrick Odoikyene of South Los Angeles, the Sheriff’s Department said.

“Patrick was always there to greet us, and he was the nicest guy,” Elise Upperman, a resident at the Shores apartment complex, said. “He always helped me lock up my bike.”

“We talked to him everyday when we walked by to go to the gym, or were just walking. He let everybody in and out,” another resident, Rory Doggett, said.

Earlier, an email sent to residents by Shores’ general manager Sue Kohan said the the incident involved a member of the apartment complex’s patrol team.

At a residents-only meeting held on Monday evening, the apartment complex’s management discussed the shooting and safety concerns of tenants.

Afterward, attendees said they had been instructed not to speak to the media about what was discussed at the meeting. However, they said they were assured that the victim had been targeted.

Authorities said this was the first homicide in Marina Del Rey in about a year.

“This area doesn’t have a lot of violent crime,” Lt. Dave Dolson of the L.A. County Sheriff’s Department said.

A woman who lives at the complex said she was shocked to hear about the homicide.

“Marina Del Rey – we’re new here, and we were told that this was a safe area. This is the reason why you pay higher rent is to get out of the L.A. crime scene,” Lynn Reynolds said. “So we’re very shocked, and we’re saddened by it.”

“It’s just really sad,” Doggett said. “I think everyone in the building knew Patrick pretty well.”

Anyone with information about this case was asked to contact Crime Stoppers at (800) 222-8477.
