Reply(1) An investigation into Thursday's shooting in Danville is ongoing. (Renee Schiavone/Patch) DANVILLE, CA — The Danville police officer involved in last week's shooting was the same man who pulled the trigger in a fatal 2018 shooting for which he was cleared but that was nevertheless questioned by some police use-of-force experts. Officer Andrew Hall was placed on paid leave per department policy after he shot a man who pulled a knife on him on Thursday, according to the Contra Costa County Office of the Sheriff. Hall responded to reports that Tyrell Wilson, a 32-year-old homeless man, was throwing rocks off the Sycamore Valley Road overpass, according to the sheriff's department. The sheriff's office alleged that Wilson pulled a folding knife and approached Hall, who fired once and struck him. Wilson was in the hospital in critical condition as of this weekend.
