OAKLAND (CBS/AP) — From Glocks, Sig Sauers and Remingtons to sniper and assault rifles, 944 guns that once belonged to law enforcement officers across California have been either stolen, lost or can’t be accounted for since 2010, often disappearing onto the streets without a trace.

More than 240 local, state and federal law enforcement agencies and discovered an alarming disregard for the way many officers — from police chiefs to cadets to FBI agents — safeguard their weapons.

The investigation comes a year after a bullet from a federal agent’s stolen gun killed 32-year-old Kate Steinle on a San Francisco pier.

The guns have been stolen from behind car seats and inside glove boxes, swiped from gym bags, dresser drawers, tailgates, and even atop a toilet paper dispenser in a car dealership’s bathroom.
