RAPID CITY, S.D. — A state prison inmate serving a life sentence for a Lawrence County murder conspiracy has died following an illness.

State corrections officials say 82-year-old Donald Wiegers died Saturday at a Sioux Falls hospital. An autopsy will be conducted.

The Rapid City Journal reports that Wiegers was sentenced to life in 1983 for conspiracy to commit murder in the 1981 contract killing of Deadwood businessman Russell Keller.

The man convicted of shooting and stabbing Keller, David Waff, is serving a life sentence at the State Penitentiary in Sioux Falls. The man believed to have masterminded the killing, Keller’s business partner and stepfather-in-law, Melvin Brown, hanged himself at the Lawrence County Jail in 1982.
