Sex, Lies and the Doctor's Wife

Overview

Karen Tipton was in the prime of her life when she was brutally attacked and murdered in her home in Decatur, Ala., in 1999. Tipton's husband, a prominent doctor, was soon ruled out as a suspect, and the focus of the investigation shifted to a young man arrested several weeks after the crime. Prosecutors viewed this as an open-and-shut case until the defense introduced issues related to alleged extra-marital affairs and use of pornography, and another theory on what may have led to Tipton's murder.
