Uncivil Twilight: The 1920s Death Sentence that Left a Serial Killer Free to Stalk and Kill Children in 1937 --Nina Martin, only 8-years-old, May Martin, just turned 12-years-old. Two sisters missing for months near the Baldwin Hills of Los Angeles. S.C. Stone, the neighborhood night watchman, was convicted of their murder. He was framed by a jailhouse snitch and a woman with something to hide, and he was sentenced to death. Los Angeles citizens were sure he was innocent. Many citizens of Inglewood were sure the man that killed Nina and May in 1924 also killed two other small sisters and their friend in 1937, when Stone was still in prison, and they knew who the real killer was. Join the factual hunt for the most cunning serial killer of the 20th century, one who was never caught, one who was happiest when someone else was convicted of his murders.
