Police are looking for the driver who fatally struck a 17-year-old girl in Port Jefferson Station and then left the scene Saturday night.

It happened on Nesconset Highway by Terryville Road shortly before 9:30 p.m.

Police say 17-year-old Jenna Perez, of Selden, was crossing the highway about 300 feet west of Terryville Road when she was hit by a vehicle that was heading west. Police say the driver left the scene.
