Provincial police are investigating after a pedestrian was struck and killed in the westbound lanes of the 401 in Tecumseh Wednesday evening.

The OPP have identified the victim as Cory Lynn Dauphin, 35, of Windsor.

The collision occurred around 6:50 p.m. on Highway 401 west of Essex County Road 19 (Manning Road).

Police are looking for the vehicle involved which did not stop following the collision.

Police say Dauphin was walking in the westbound lanes of the 401 Highway when she was struck by a motor vehicle that did not stop at the collision and has yet to be identified.

It is still unknown why Dauphin was on the highway, although a blue Chevrolet registered to her was parked on the shoulder near the collision scene.

Witnesses have told police that vehicles, including a tractor trailer occupied by two men had stopped shortly after the collision but did not provide their names and left the scene prior to police arriving.

The OPP are requesting that anyone that stopped at this collision or may have been in the vicinity of the 401 Highway west of Manning Road at approximately 6:50 p.m. Wednesday evening, immediately contact them at 519-723-2491.
