(AP) – An Overland Park woman who was under the influence of drugs when she hit and killed a grandmother who was gardening in her yard has been sentenced to three years and five months in prison.

Jill Conaghan pleaded no contest Friday to involuntary manslaughter in the July 2009 death of 70-year-old Sandra Carocari. Conaghan also was sentenced to a concurrent term of six months for leaving the scene of an accident.

Carocari was gardening at her Overland Park home when a van driven by Conaghan, then 19, veered off the road and hit her. She died at the scene.

Conaghan, who was under the influence of drugs, left the scene but returned later with her father and admitted the crime.
