Detectives decided that the most significant of all were the address lists. ''The main crux of our search always was geographical," said Lt. Kenneth Landwehr of the Wichita Police Department. "According to the behavioral scientists, the individual lived close to where he was striking."
Once the lists were completed, investigators used their computer to try to come up with a more precise list of suspects. The computer gave them 225 possible suspects, most of whom no longer resided in Wichita. One by one, the detectives set out to eliminate each of the 225 possible suspects.
One of the key pieces of evidence that the killer left behind was his semen. Lab technicians were able to determine that it was a type of semen found in fewer than 6 percent of all males. Police will not comment as to the type, citing their rules of evidence.
