Police say a man whose body was found off a Salt Lake City-area interstate was likely a hit-and-run victim.

Utah Highway Patrol officials said Monday the body had been on the side of Interstate 215 for up to three weeks before it was found by a construction worker Saturday morning.

They say it was badly decomposed; medical examiners are still trying to identify the man.

Meanwhile, investigators are now looking for the driver who hit him.

Police are asking anyone with information about a car with damage to its right front corner to call the Utah Highway Patrol.
