STOCKTON — Four people were shot, one fatally, in the 600 block of East Oak Street at about 9:15 p.m. Sunday night, Stockton police reported.

Stockton police arrived at the scene, where medics pronounced one person dead, while others were transported to area hospitals for treatment.

The incident remains under investigation.

The deadly shooting was the second homicide Sunday night; the first occurred at about 7:30 p.m. in the 8100 block of Palisades Drive. Police were called to the scene on a report of a shooting. When officers arrived, they located an adult male who had been shot. He was pronounced dead at the scene.

At this time, there is no motive or releasable suspect information.

The homicides come amid an uptick in violence in Stockton, which Mayor Michael Tubbs addressed in his State of the City Address on Thursday.

At about 11:04 p.m. Thursday, 24-year-old Jose Pablo Flores Martinez of Lodi was found inside a vehicle with a gunshot wound shot near Sierra Nevada and Poplar streets, in what then had been the city’s 18th homicide of the year and the third in five days; Sunday’s slayings bring that number to 20.

On Tuesday, officers found 22-year-old Andrew Stephano Molinares in the 3000 block of Monte Diablo Avenue near Louis Park with a gunshot wound. Molinares was pronounced dead at the scene. Last Saturday, officers found 26-year-old Joshua Emmanuel Moorer dead in an apartment complex in the 200 block of East Bianchi Road at 4:04 p.m.
