Wendy McDade was 29 and a Broadway chorus performer when she was found shot to death alongside William Callahan in a field in Pleasant Prairie, Kenosha County, Wisconsin. The bodies were discovered March 18, 1981; both victims had been shot multiple times, and several accounts report each was shot three times in the head, a pattern that investigators described as resembling an execution. The scene and the fact that Callahan’s valuable wristwatch and about $1,500 in Canadian currency were left with his body led investigators to question robbery as the motive.

Attention quickly focused on Callahan’s recent financial troubles. Court records later showed he had diverted millions from Arc Electrical Construction through fictitious invoices and associates and had left New York after being forced out in September 1980. Authorities examined people tied to his financial schemes, including a lawyer and a convicted con artist mentioned in later reporting, but no one has been charged. The Kenosha County Sheriff’s Office continues to list the Pleasant Prairie killings as unsolved.

Does anyone have information about Callahan’s associates or McDade’s activities in Chicago in March 1981?
