A San Bernardino pawn shop employee wounded in a shootout with two armed robbers Wednesday afternoon has died, San Bernardino police officials said Thursday, and police are looking for witnesses to help find the shooters.

Jason Cullen, 32, of Highland was shot and fatally wounded in the robbery attempt just before 1 p.m. Wednesday, Jan. 10, at the pawn shop at 2601 Highland Ave. in San Bernardino. Police had previously identified Cullen as a pawn shop employee.

Police said that two suspects wearing surgical masks threw an incendiary device that resembled a Molotov cocktail into the shop, prompting a display case to catch fire. Two people suffered burn wounds; they are expected to recover.

The suspects then opened fire, police said, and employees at the store fired back.

It wasn’t clear whether the robbers were wounded during the shooting, which some witnesses said unleashed between six and 10 bullets.

The armed men fled, driving south on Valaria Drive, but crashed their car at a fence at the 210 Freeway, officials said. Authorities briefly closed the freeway during the search for the suspects.

Police said the suspects then fled on foot into a nearby apartment complex, but were not found.

They are described as black, in their mid-20s with medium builds last seen wearing black hoodies, black pants and wearing surgical masks. They are believed to be armed. Police ask anyone who sees them to call 911.
