SAN FRANCISCO (KRON) — Amended charges were filed Tuesday in San Francisco’s Superior Court against the man accused of killing a woman on the Embarcadero.  The amendment includes a new charge of a felon in possession of a firearm.

45-year-old Francisco Sanchez pleaded not guilty to firing the fatal shots that took the life of 32-year-old Kate Steinle as she walked down San Francisco’s popular Pier 14 arm-in-arm with her father on July 1st.

In a 10-minute court hearing, Sanchez listened in with the help of an interpreter to the new charges he will face in court.  The judge set a preliminary hearing date for August 25.

Sanchez claims he found an officer’s gun wrapped in a t-shirt, and when he picked it up, the gun accidentally discharged.  Sanchez was released in San Francisco because of its sanctuary city policy, despite the fact that he was a convicted felon with five previous deportations back to Mexico.

Steinle’s murder has drawn national attention and called into question the efficacy of sanctuary city policies.
