72 Hours: True Crime

T03:C312 - S03:E312 - Bull's Eye

A Girl Guide leader is found dead in her home on the floor of her bedroom. As there is no obvious cause of death, police are suspicious. When an autopsy reveals a small bullet lodged within the victim's brain with an entry wound through the left eye, detectives learn they're investigating a murder. The suspects include a lying husband and a violent and abusive son, both of whom are members of a local gun club. Each man blames the other, and detectives have to solve the mystery piece by piece, starting with a love letter found in the bottom of a drawer.
