44-year-old David Bowen of Portland pleaded guilty in September to the murder of Kenneth ":Butch": Conrick in exchange for a maximum 50-year prison term.
Conrick was reported missing on Oct. 15, 1979. His body was found 13 days later, in a wooded area near his family’s Gary home.
Authorities said his body showed signs of brutal, prolonged torture.
DNA evidence that was unavailable 29 years ago later helped police link Bowen to Conrick’s death. He was arrested last December in Maine and extradited to Indiana.
Bowen told the court that something was wrong with him when he committed the crime.
