A West Valley police public relations officer is being credited with saving the life of a Salt Lake County man whose leg was severed in a truck-motorcycle collision.

Sgt. Kelly Davis said Troy Allen Wardle, 22, was flown by air ambulance to LDS Hospital following the 4 p.m. accident at 2902 W. Parkview Blvd. (2650 South).A truck was going west on Parkview and attempted to make a right turn when it collided with Wardle's vehicle, Davis said.

When Officer Guy Dodge, who was nearby, arrived at the scene, he applied pressure to the wound to prevent Wardle from bleeding death, Davis said.

Wardle was in critical condition Thursday, a nursing supervisor said.
