Kazimiera Paruch, a 43-year-old white woman of Polish descent, was murdered on March 4, 1997, in Chicago. She had been advertising her condominium for sale and encountered the killer while doing so. Investigators say she was sexually assaulted and strangled, and her home was set on fire; the blaze was ruled arson and appears to have been started to destroy evidence.

Police identified Paul Frederick Runge as the suspect. Runge, already a convicted violent offender on parole, had a pattern of contacting women who were selling items or property, gaining access under false pretenses, then sexually assaulting and killing them and sometimes setting fires. He was arrested in May 1997 on a parole violation, and subsequent investigations linked him to multiple murders, including Paruch’s. She was among several victims whose deaths resulted in Runge receiving life imprisonment without the possibility of parole.

Does anyone have memories of Paruch, details about the condominium listing, or information that could shed light on her last contacts?
