LOWER SOUTHAMPTON, Pa. (CBS) – Police in Bucks County are searching for the driver accused of fatally striking a woman and injuring a man on Monday night.

It happened around 8:15 p.m. along Street Road, near Philmont Avenue in the Trevose area.

Lower Southampton police say the man driving the truck apparently stopped briefly at the scene to help move the teens to the side of the road but then drove off.

An 18-year-old man and a 19-year-old woman were both taken to a local hospital.

On Tuesday night, authorities said 19-year-old Jess Kurtz died from her injuries. Will Vanarsdale,18,  suffered minor injuries in the accident.

Vanarsdale told Eyewitness News that he wants the hit-and-run driver to know that he finds him "disgusting".

Police are looking for a late-model two-tone maroon and tan, or gray, Ford pickup with a ladder rack and ladder attached, and damage to the right-front side.

Witnesses describe the driver as a black male, around 30 years old, thin build, around 6 feet tall and last seen wearing a blue baseball cap, possibly a Knicks cap, a black shirt and dark jeans.

Anyone with any information is asked to call police at (215) 633-3719.
