(WIBW) - It's the story of a couple, seemingly without enemies, shot dead in their home, with all the evidence pointing to one person - a person who even her children believe committed the crime.
It's a story that intrigued 48 Hours Executive Producer Susan Zirinsky.
So much so, the real-life killings of Topekans Karen Harkness and Michael Sisco will be featured on the national news magazine Oct. 24 at 9pm on WIBW-TV.
48 Hours and its CBS News staff spent more than a year looking into the case. They interviewed family members and authorities who worked on the case. They even had new detectives revisit the crime scene.
Zirinksy says she feels the attention the program is able to bring to cold cases can make a difference. She says it often gives a fresh set of eyes and more exposure to the incident.
Topeka Police will be staffing a special hotline during the show Saturday night to take any tips.
