SIOUX FALLS, S.D. (AP) — A Harrisburg man has admitted emptying his grandmother's savings account of $62,000 and using much of the money for personal bills, including a settlement with his ex-wife.

The Argus Leader reports that 44-year-old Troy Derrick pleaded guilty Wednesday to grand theft and petty theft charges in a deal with prosecutors under which he would spend up to a year in jail. He also could get 10 years of prison time suspended on the condition he make restitution.

A sentencing date was not immediately scheduled.

Authorities say Derrick's grandmother had dementia and was in an assisted living center. She has since died. Derrick was given power of attorney over his grandmother's accounts in 2005 and had been in charge of the money since his grandfather's death in November 2012.
