UNION CITY -- Authorities have identified a man who was shot and killed by Union City police Saturday after he fired a gun 10 to 15 times near homes and then pointed his handgun at officers.

Union City police Cmdr. Ben Horner identified the man as Vergel Ricafrente Worrell, 46, of Union City.

Horner said that at 2:30 p.m. Saturday, the department received multiple 911 calls about a man walking around and randomly firing a gun in the 32600 block of Kenita Way in Union City. No one was hit or injured.

Witnesses told police that Worrell was "acting incoherent and screaming profanities," according to a police news release.

Police brought in a negotiator and an officer trained to talk to people with mental illness but those attempts to calm Worrell failed. When he pointed his handgun directly at police officers, he was shot and killed, police said.

The officer who shot Worrell has been placed on paid administrative leave. His name was not released.

The Alameda County District Attorney's office is continuing an independent investigation of the shooting and the Union City investigators are looking into Worrell's background to try and determine the motive for his sudden and violent behavior, police said.

Saturday's shooting was the second time in six months Union City police officers have shot and killed a man. On March 2, officers shot a 26-year-old man who they said refused orders to stop and then pointed a gun at them. The man died later at the hospital.
