A prosecutor says a Kentucky man posed as a repairman to get into an 87-year-old Ohio woman's house, then shocked her with a stun gun, choked her and cut her throat.

Butler County Prosecutor Michael Gmoser told jurors Wednesday in opening statements of 57-year-old Daniel French's trial in Hamilton that French killed Barbara Howe in 2012 after telling her he was there to repair a medical alert system.

Gmoser says French then put Howe's body in the trunk of her car and poured peroxide on her.

Defense attorney Lawrence Hawkins III says French caused Howe's death but didn't purposely kill her. He says French only planned to steal from Howe.

French has pleaded not guilty to aggravated murder. It could carry the death penalty with conviction.
