Provincial police are urging a driver to get a lawyer and turn themselves in after a crash on Highway 400 early Friday that killed a woman and injured three other people.
The two-vehicle collision happened around 3 a.m. in the southbound lanes near the exit for Rutherford Road in Vaughan.
The driver of a red Volkswagen Jetta sedan slammed into the back of a minivan with four people inside, according to police.
A 73-year-old woman from North York was pronounced dead the scene, police said. The three other people in the van were taken to hospital with minor injuries.
The driver of the sedan walked away from the crash and police are looking for that person. OPP Sgt. Kerry Schmidt said in a tweet the suspect is described as a man, 35 to 40 years old, with a thin build, wearing blue jeans and carrying a reusable shopping bag.
Investigators are currently "following up on tips" about their whereabouts, police said.
The southbound lanes of the highway were all closed throughout the morning rush hour, but have since reopened to traffic.
