Authorities have released new details about a police response that left a 19-year-old dead and an 18-year-old injured in Anaheim over the weekend.
Officers were conducting gang-suppression patrols around 9:30 p.m. Saturday when a group they attempted to contact on South Philadelphia Street ran toward a nearby residence, the Anaheim Police Department said in a Facebook post Wednesday night.
Officers pursued and attempted to detain 19-year-old Alberto Arzola, who police said struggled with officers.
“One officer discharged his firearm, and Mr. Arzola was pronounced deceased at the scene. A loaded assault-style firearm was recovered next to him,” police said.

A crowd formed immediately after the shooting, and more than a dozen people were detained from the house where the shooting occurred.
About 15 minutes later, police said 18-year-old Emmanuel Cordova jumped from the backyard into the front yard and ignored commands from officers.
Police fired a single less-lethal beanbag round at Cordova, who was treated at a local hospital for a minor injury.
“A video circulating online shows the less-lethal incident involving Mr. Cordova, not the shooting of Mr. Arzola,” police said.
The incident is being reviewed by the Orange County District Attorney’s Office, Anaheim Police Department detectives, Internal Affairs and the Major Incident Review Team.
Anyone with information is asked to contact Orange County Crime Stoppers at 855-TIP-OCCS.
