Leonard Thomas Lake (October 29, 1945 – June 6, 1985), also known as Leonard Hill and a variety of other aliases, was an American serial killer. During the mid-1980s, he and his accomplice, British Hong Kong born Charle NG, raped, tortured and murdered an estimated eleven to twenty-five victims at a remote cabin near Wilseyville, California, in the Sierra Nevada foothills, located 150 miles east of San Francisco. After his 1985 arrest on unrelated charges, Lake swallowed cyanide pills that he had sewn into his clothing and died four days later. Human remains, videotapes, and journals found at Lake’s cabin later confirmed Ng’s involvement and were used to convict Ng on eleven counts of capital murder.
