Details of Disappearance

This was not a murder by Edward Edwards like the two teenagers who died a few years later. Getting that out of the way. Also Rodney Alcala was still in prison when Catherine went missing.

She was last seen leaving Concord Center House from the Oconomowoc High School post-prom party during the early morning hours. She got into an argument with her boyfriend at 3:00 a.m. and then left.The prom was held at the Jefferson County Concord House dance hall, on an interstate 94 interchange in Concord. She was later seen in Delafield walking home. The land around Concord House has been most deforested by now, but even then it was thoroughly searched. After passing a polygraph test, the boyfriend was ruled out as a suspect in Cathy's disapperance. I believe Delafield area needs to be searched, see article below.
