In 1981, six-year-old Cassie Hansen disappeared from her St. Paul, Minnesota church during a evening service. After a tip from a witness that an older man was seen carrying a small body, Cassie's body was found in a dumpster. The FBI created a psychological profile of the perpetrator, but are still unable to find the killer. Dorothy Noga contacted police to let them know that Stuart Knowlton was a massage client that liked to discuss his fantasies during his weekly massages and that one fantasy he spoke of closely resembled the church abduction, which caught her attention. Knowlton had also asked Noga to be his alibi on the night of the murder. Even though she was later attacked by Knowlton and stabbed 32 times, Noga testified against Knowlton in the trial. Knowlton died in prison in 2006.
