Livermore police officers are searching for a 21-year-old man suspected of fatally shooting a 16-year-old boy during a verbal dispute on Monday, authorities said.

Detectives believe Jorge Luis Tellez, of Livermore, opened fire on the teenager during a verbal altercation at 985 E. Stanley Boulevard on Monday, according to the Livermore Police Department.

The teen, whose name has not been released by police or the Alameda County Coroner’s Bureau, was taken to a local hospital and later died from at least one gunshot wound to his abdomen.

Officials said the two were involved in an argument before Tellez allegedly pulled out a firearm, shot the teen, and fled the scene. Officers responding to a report of a shooting found the teen with a gunshot wound at the location, which is listed as a Taco Bell restaurant.

The Police Department’s SWAT team served a search warrant on Tellez’s Livermore residence Tuesday morning, but he was not home, police said. An arrest warrant has been issued for Tellez on suspicion of murder, police said.

“Jorge Tellez should be considered armed and dangerous,” police said Tuesday.
