Margaret Campbell (April 24, 1883 – June 27, 1939), circa 1928
In 1939, Campbell was murdered by her son; she was sexually assaulted and bludgeoned to death with a hammer. The son was also suspected of having murdered a Russian dancer, Anya Sosoyeva, who was bludgeoned to death, and assaulted the young actress Delia Bogard who survived. He was later cleared of those murders when the actual murderer, De Witt Clinton Cook, was captured by the Los Angeles police force. Both attacks occurred on the Los Angeles City College campus.
