READING, Pa. (AP) — A New Jersey man already serving a prison sentence for dragging his girlfriend behind his pickup truck is now on trial for murder in her death from injuries police say resulted from the same incident.

Michael Morrone is charged with third-degree murder in the death of Christine McGhee, who was left in a vegetative state after she was dragged across a Kutztown University parking lot in December 2008.

Morrone, of Marlton, N.J., was convicted in 2010 of aggravated assault and related charges and is currently serving a five- to 20-year prison sentence.

He was charged with murder after the Berks County coroner determined McGhee, of Warminster, Bucks County, died on March 2012 of brain injuries from the incident over three years earlier.

Morrone’s trial got underway Monday in Berks County.
