This episode covers the murder of Kathy Lauric in Concord, California, the investigation that followed, and the eventual identification of Robert Frazier as the killer.
Kathy Lauric was murdered during her lunch break while walking along a jogging trail. Her husband reported her missing after hearing a gasp during their phone call. Police found her barely alive, but she died en route to the hospital.
Investigators discovered Kathy's cell phone was used after her murder, leading them to Juan Sanchez, who claimed he found it. However, he was cleared as a suspect. Witnesses described a man near the trail, leading to a composite sketch.
The investigation took a turn when they identified Mark Fisher, who resembled the sketch and had a violent history. Fisher committed suicide shortly after Kathy's murder, but DNA evidence did not link him to the crime.
Eventually, Robert Frazier was identified as a suspect after a mountain biker recognized him. DNA from cigarette butts and the murder weapon linked him to the crime. Frazier was convicted of first-degree murder and sentenced to death.
Kathy Lauric was murdered in Concord, California; Robert Frazier was identified and convicted as her killer.
