Police have released a motive in the slayings that shook the small town of Manchester, Illinois.
Rick Smith shot six people, killing five, on the morning of April 24 at a Manchester home. Investigators now believe Smith planned the attack to resolve a custody battle over his three-year-old daughter. Smith believed the family of the girl's mother was interfering in the couple's custody dispute.
Police have also learned that Smith did not stray more than 25 miles from the crime scene before he started a shootout with police. Smith was killed in that shootout. A six-year-old girl survived the massacre.
