York Regional Police are investigating a fatal hit-and-run in Richmond Hill after a 27-year-old pedestrian was struck by two vehicles Wednesday night.

Officers were called to the area of Yonge Street and Tower Hill Road at approximately 9:20 p.m. on Wednesday. The pedestrian, who was identified as a man with no fixed address, was found without vital signs by emergency responders and later pronounced dead.

Investigators believe the man was initially hit by a northbound vehicle and thrown into the southbound lanes, where he was struck again by another vehicle travelling in the opposite direction. The second driver reportedly left the scene without stopping.

The driver of the first vehicle remained at the location and cooperated with police.

Investigators have not released a description of the second vehicle, and no charges have been announced. The roadway closures put in place during the investigation have since been lifted.

Police say the investigation is continuing.
