I Am Cain

On the night of April 7, 1990, newlyweds Nancy and Richard Langert were brutally shot in the basement of their suburban Chicago home. There were no leads. Nothing was stolen. The only clue was an illegible message Nancy left behind, written in her own blood. It was a crime that shocked the community and baffled the FBI and seven local police departments. They explored every prospect -- from IRA assassinations to Mafia hit. But it was a tough Illinois policewoman who would track down the killer, exposing a horror that was shockingly close to home. Veteran Chicago journalists Gera-Lind Kolarik and Wayne Klatt present a chilling investigation into this true story of murder, compulsion and tragedy.
