The family of an artist killed with a federal agent's stolen gun is suing the U.S. Immigration and Customs Enforcement agency.
A gunman fatally shot 27-year-old Antonio Ramos in September 2015 while the artist was paining a mural in Oakland.
Investigators say a handgun stolen from an ICE agent's car parked in San Francisco was the murder weapon.
San Francisco was experiencing an epidemic of car burglaries and 57 firearms were reported stolen that year, including a number from law enforcement officials.
The gun used to kill Kate Steinle on the San Francisco waterfront in July 2015 was stolen from a Bureau of Land Management agent's vehicle. Steinle's family is suing BLM.
ICE declined comment Thursday, a day after the wrongful death lawsuit was filed in San Francisco federal court.
