Investigators say they've solved the 1984 bludgeoning deaths of a mother, son and her son's fiancee in southern Iowa. The Iowa Division of Criminal Investigation and officials from two sheriff's offices announced Friday DNA links the case to a convict executed by Missouri in 1997 for killing a 12-year-old girl.
The Iowa Division of Criminal Investigation said Andrew Six was responsible for the bludgeoning deaths of 20-year-old Justin Hook Jr., his fiancee, 19-year-old Tina Lade, and Hook's mother, 41-year-old Sara Link.
Firefighters found Hook's body outside his burned-out mobile home in rural Drakesville in April 1984. A farmer found Link's body the following week in a wooded area near Eldon. Two days later, police dogs discovered Lade's body in a ravine a half-mile away. All three were killed by trauma to the head.
Missouri authorities executed Six by lethal injection for the 1987 kidnapping and murder of Kathy Allen. Six and his uncle kidnapped the girl from the Allen family's trailer in Ottumwa, slit her throat and dumped her body in northern Missouri.
Retired DCI supervisor Sam Swaim said Six was always a suspect in the earlier triple homicide, but investigators did not have enough evidence to charge him.
