Ontario Provincial Police say they want to talk to a driver who stopped at the scene of Sunday's fatal collision on the 417.
42-year-old Bernard Clarke died of his injuries and a second man was seriously hurt when their cars collided on the highway, near Woodroffe, Sunday afternoon.
Police say the male driver of a 2000s-model silver or grey Honda Civic hatchback stopped at the scene of the crash to check on the people involved, but he left before police arrived.
The O.P.P. is asking for this driver to contact the Ottawa Detachment at 613-270-9171 and for anyone who may have knowledge of that vehicle to also contact the O.P.P.
