Police from Bayview Station responded to the intersection of San Bruno Avenue and Woolsey Street at 9:54pm, where they found a woman in her fifties with serious injuries. 

The victim was transported to a hospital for treatment, but the suspect was observed fleeing the scene in a vehicle that was not described.
