At approximately 2:50 a.m., on Thursday, June 18, 2009, a yellow 2005 Dodge Ram pick-up truck was traveling east on Glenmore Trail when it collided with the rear of a large commercial vehicle near 52 Street SE in Calgary, Alberta.

The 32-year-old driver of the Dodge Ram, Ryan James WALD died at the scene. There was no one else in the vehicle.

The large commercial vehicle did not remain at the scene. Police now believe that the driver would have known he was involved in the collision but has so far failed to come forward.

The vehicle is a large, white Columbia Freightliner with a 53-foot-long refrigerated trailer. The trailer is likely to have some damage to the passenger-side tail light area and may have some yellow paint from the Dodge Ram. To assist with the investigation, police are releasing a photograph of the vehicle that was involved in the collision.

Given the nature of the haulage industry, this vehicle could now be anywhere in Canada and could even have gone abroad.

Anyone who may be able to identify the driver of this vehicle or who has any information relating to the collision is asked to call 1-800-222-8477 to submit anonymous information.
