SAN DIEGO – Authorities are investigating five separate shootings across several San Diego neighborhoods that killed one person and wounded six others over the weekend.

Investigators asked the public to come forward with information on the incidents that happened in a roughly 30-hour span starting Saturday with the last one reported just before 5 a.m. Sunday. None of the incidents immediately appear to be related, but the bloody weekend prompted some fear among nearby residents as police attempted to track down those responsible for carrying out the shootings.

One of the five shootings killed a 41-year-old man in the Linda Vista neighborhood. The man was found dead in a driveway off the 2200 block of Ulric Street after he was shot in the back early Sunday.

By Monday, a memorial was established and growing in the immediate area where he was found.

A few hours before that, a man was shot at the BLVD 63 apartment complex off El Cajon Boulevard in the College Area. Police said a man was found shot at the apartment complex and when paramedics and officers tried to enter the building, a large group came out from the building and onto the street.

One resident of the complex told FOX 5 he heard the shooting, noting it as a rare occurrence in the year he’s lived there.

“I just heard gunshots randomly around 1:30,” he said. “I just stayed inside and I saw the police running through the building.” 

Elsewhere, about 10:40 p.m. Saturday, three people were shot outside a party at a home in the 4800 block of Beech Street in the Ridgeview-Webster area. Three victims were transported to the hospital with non-life-threatening injuries. Investigators are trying to determine if the incident was a shootout.

According to police, there was a party at the home when several people at the party heard gunshots and went to the front of the house and saw three men, ages 22, 33 and 37, on the front lawn suffering from gunshot wounds.

Nobody saw the shooting, officers said, and no suspect information was released by the agency.

Two more shootings happened Saturday, but the times and the extent of victim injuries were unknown. One person was shot Saturday in the 5700 block of Luber Street in a Mid-City neighborhood, according to police. The shooting was not fatal.

Another non-fatal shooting Saturday happened in the 4300 block of Imperial Avenue.

“At night time, no, you’re not going to find me here,” Jose Rosas said, who works near where the shooting happened on Imperial Avenue in the Mountain View neighborhood. “It’s not a very safe area. I would not like my family members around here.”

Police said they have made arrests in some cases and were pursuing leads in others, but need the public’s help in all cases, even if an arrest has been made.

Anyone with information about these five shootings was urged to contact police at 619-531-2293. Tips also can be called in anonymously by calling Crime Stoppers at 888-580-8477.
