SAN FRANCISCO — Lawyers at Cotchett, Pitre & McCarthy have sued the federal government on behalf of the family of an Oakland artist shot and killed with a gun stolen from Immigration and Customs Enforcement.

Antonio “Tony” Ramos, 27, was gunned down on Sept. 29, 2015, in West Oakland while working on a community anti-violence mural project. According to the complaint filed Wednesday in U.S. District Court for the Northern District of California, Ramos' murderer, a member of a gang that claimed the mural's location as its territory, shot him using a stolen Glock 26 9mm handgun. The gun was a government-issued duty weapon that belonged to an ICE officer that was stolen about two weeks prior to Ramos' murder. The officer left the gun in a bag in an unattended rental vehicle.

“It was foreseeable that leaving a bag in plain sight in a rental vehicle parked on the street in a high-auto theft and break-in neighborhood would result in the vehicle and/or bag's theft, and thereby result in the theft of a firearm and ammunition, in this case specifically,” wrote Cotchett Pitre's Alison Cordova. “It was also reasonably foreseeable that a firearm and ammunition once stolen, would then be used in the near future to pursue a criminal course of conduct.”
