SAN FRANCISCO (KGO) -- The suspect in the Pier 14 shooting in San Francisco has signed a confession. Sources tell ABC7 News 45-year-old Francisco Sanchez admitted to firing the fatal shot that killed Kathryn Steinle.

Investigators say he is on probation from Texas and has committed offences in numerous states. They say Sanchez did not know his victim and they still don't have a motive for the killing. Police divers have found a gun in the water near the pier. They are carrying out ballistics tests to see if it was used in the shooting.

Steinle was walking arm-in-arm with her father when she was shot Wednesday night. Her father had come to San Francisco to take her back to Pleasanton for a family party.
