Police have found bloody clothes stashed in the ceiling of the lab where Annie Marie Le, a 24-year-old Yale grad student, who disappeared five days before she was to wed, worked and was last seen, the New York Daily News reports. Investigators have named no suspects and denied finding a body. According to fellow students, Le and her fiancé were an extremely happy couple. "She showed me her engagement ring when she came to see my lab," Le's former professor says. "They seemed very happy." Investigators have reportedly questioned a professor who canceled a class after Le's disappearance but before it had been announced, and are also considering that the crime was a burglary gone bad in the lab, or a kidnapping.
