In the early hours of January 15, 1978—one week after his arrival in Tallahassee—Bundy entered FSU's Chi Omega sorority house through a rear door with a faulty locking mechanism. Beginning at about 2:45 a.m. he bludgeoned Margaret Bowman, 21, with a piece of oak firewood as she slept, then garroted her with a nylon stocking. He then entered the bedroom of 20-year-old Lisa Levy and beat her unconscious, strangled her, tore one of her nipples, bit deeply into her left buttock, and sexually assaulted her with a hair mist bottle. In an adjoining bedroom he attacked Kathy Kleiner, breaking her jaw and deeply lacerating her shoulder; and Karen Chandler, who suffered a concussion, broken jaw, loss of teeth, and a crushed finger. Tallahassee detectives later determined that the four attacks took place in a total of less than 15 minutes, within earshot of more than 30 witnesses who heard nothing. After leaving the sorority house, Bundy broke into a basement apartment eight blocks away and attacked FSU student Cheryl Thomas, dislocating her shoulder and fracturing her jaw and skull in five places. She was left with permanent deafness, and equilibrium damage that ended her dance career. On Thomas's bed, police found a semen stain and a pantyhose "mask" containing two hairs "similar to Bundy's in class and characteristic".
