HIDDEN VALLEY, Ind. (WKRC) – Evidence in the murder of Tom Biedenharn suggests more than one person was involved in his death, Indiana State Police said Tuesday. The revelation comes as Biedenharn’s family renewed its plea for information in the case by putting up a $50,000 reward.

Biedenharn was found murdered in his home in Hidden Valley, Indiana on May 28 which was Memorial Day afternoon. Biedenharn, 73, spent his retirement helping people. He volunteered for several years at the Grateful Life Center in Erlanger, Kentucky. The center is a rehabilitation facility for drug addicts. He and Doug Boschert taught life skills classes in finance and communications to recovering addicts.
