South San Francisco police have identified an at-large suspect in a Monday afternoon double shooting that killed one man at a park and left the other victim hospitalized.

Police are looking for Christian Omar Cruz, 19, of South San Francisco in connection with a homicide at Orange Memorial Park.

Police headed to the 600 block of First Lane around 2:45 p.m. on reports of “adults involved in an altercation,” authorities said. Investigators learned the fight moved to the park, where the gunman shot both of the victims once in their abdomens.

Officers found two gunshot victims at the scene, and paramedics rushed them to a trauma center. One of the victims was in surgery with a life-threatening injury but later died. The other was in stable condition, police said Monday night.

Authorities were looking for the shooter, who officials said should be considered “armed and dangerous.” He was spotted running west through the park with the gun after the shooting. The event prompted a temporary lockdown at nearby schools and community centers, police said.

Anyone with more information on the shooting or the whereabouts of Cruz is asked to call 911 or their local law enforcement agency.
