The gun used in the fatal shooting of a woman on a San Francisco pier belonged to an agent with the Bureau of Land Management, a Department of Interior agency, according to multiple law enforcement sources familiar with the investigation.
Sources could not immediately confirm how Juan Francisco Lopez-Sanchez, the undocumented immigrant charged in the killing, obtained the weapon. It was described as a large-caliber handgun.
The unidentified federal agent's weapon was stolen after being left in a vehicle, the sources said. It was not immediately clear when the gun was taken.
The sources told NBC News the firearm did not appear to be government-issued. They stressed the information was preliminary and the investigation was ongoing.
Sanchez is being held on $5 million bail. Prosecutors had argued for $10 million.
