Richard Speck
At 11:00 p.m. on July 13, 1966, Speck broke into the 2319 E. 100th St townhouse in Chicago's Jeffery Manor neighborhood; the townhouse was functioning as a dormitory for student nurses. Armed with only a knife, he entered and then killed Gloria Davy, Patricia Matusek, Nina Jo Schmale, Pamela Wilkening, Suzanne Farris, Mary Ann Jordan, Merlita Gargullo and Valentina Pasion. Speck, who later claimed he was both drunk and high on drugs, may have originally planned to commit a routine burglary. Speck held the women in a room for hours, leading them out one by one, stabbing or strangling each to death, then finally raping and strangling his last victim, Gloria Davy. One woman, Corazon Amurao, escaped death because she crawled and hid under a bed while Speck was out of the room. Speck possibly lost count or might have known eight women lived in the townhouse but did not realize a ninth woman was spending the night. Amurao stayed hidden until almost 6 a.m.
