Lehenbauer Sentenced for Role in Arnette Murder
A Hannibal woman pleads guilty to her part in a convenience store robbery that resulted in the death of a store clerk.
24-year-old Amanda Lehenbauer pleaded guilty to involuntary manslaughter and second degree robbery in Marion County Circuit Court. She was sentenced Monday to six years in prison on each count to be served consecutively.
Lehenbauer admitted that she and two others were in a van waiting for Michael Studer and Gary Wiltermood III outside Abel’s Quik Shop on the night of October 8. The two men robbed the store and shot 61-year-old Adrienne Arnett to death.
Studer and Wiltermood are both serving prison sentences. The two others in the van with Lehenbauer are awaiting court dates.
