The Thornton Police Department has issued a Medina Alert, following a fatal collision that occurred on I-25 during the evening of August 24.

According to police, a Yamaha motorcycle was traveling northbound on I-25 between 120th Avenue and 136th Avenue around 8:19 p.m., when it collided with a black pickup truck. The motorcyclist, who has yet to be identified, sadly died on scene. The driver of the pickup fled following the accident, and Thornton Police are now trying to find the person who was behind the wheel.

Police are asking the public to keep an eye out for a black pickup truck, that might possibly have damage to the passenger side quarter panel and front side corner. Although the exact license plate number is unknown, it was reportedly a Colorado plate.
