Lorenzo Ambrosio, 39, was shot while riding a bicycle west on West Jefferson Boulevard near Ninth Avenue in Jefferson Park late on March 14, 2016. LAPD says a white, four-door sedan approached around 11:40 p.m. and someone inside opened fire. Others in the area returned fire and the sedan fled east on Jefferson Boulevard. Ambrosio was taken to a hospital and died the next day on March 15, 2016.

The Los Angeles Police Department’s Criminal Gang Homicide Division handled the investigation. No arrests have been announced and detectives describe the case as unsolved. Investigators have asked the public for information and provided channels for anonymous tips.
