What to Know: Possible Serial Killer Tied to Stockton, Oakland Homicides

Northern California authorities are on the hunt for a possible serial killer following the shooting deaths of six people in Stockton and Oakland dating back to last year.

Ballistics tests and some video evidence linked the crimes in the two cities, which are about 70 miles apart, police said.

Here's a look at the cases, information about a person of interest, how to submit tips and more.

Timeline of Attacks and Victims Identified

Authorities believe the cases listed below are related.

April 10, 2021 – A 40-year-old Hispanic man was fatally shot at about 4:18 a.m. in Oakland. The victim, identified as Juan Vasquez Serrano, was shot multiple times, according to the Alameda County coroner’s bureau.

April 16, 2021 – A 46-year-old Black woman, identified as Natasha Latour, was shot and injured at about 3:20 a.m. in the area of Park and Union streets in Stockton. She told investigators that she was inside her tent when she heard someone walking around outside. The suspect fired multiple shots, wounding Latour, but she tried to defend herself by advancing toward her attacker. The shooter lowered the gun.

"There were no words exchanged, they didn’t say anything, didn’t come any closer, just started shooting," Latour said in an interview. "I cry a lot."
