The driver of one of three vehicles involved in an accident that left four people in critical condition has turned himself in.

On Saturday evening, a Toyota Camry and Mitsubishi RVR collided head-on just north of Mansfield, on Airport Rd. between Dufferin County Rd. 17 and Side Rd. 15.

A Volkswagen Passat then struck the Toyota Camry and the driver allegedly fled the scene. Charges against the man, 19, are pending.

Ontario Provincial Police determined the make and model of the car from debris left at the scene.

The initial collision left the driver of the Mitsubishi, a 53-year-old man, with critical injuries including a broken femur, a broken sternum, a broken wrist and head injuries. The passenger, 20, was released from hospital.

The driver of the Toyota, a 58-year-old woman, had to be transported to hospital, having sustained injuries to her back, her chest and to her right leg and foot. She was also suffering from pain in her neck. An 18-year-old male passenger was also brought to the hospital, but was released.

Seated in the back seat of the Toyota, a 51-year-old man suffered a dislocated right hip, a broken left hip and a broken shoulder and had to be air-lifted to hospital. A 35-year-old woman was transported to a local hospital after she suffered fractures to both femurs, her pelvis and suffered internal bleeding.

The investigation continues.
