Police in Thornton are trying to learn the identity of a body found in a sport utility vehicle in a small retention pond.
Police say they do not know whether the victim is a man or a woman, or how long the body was submerged.
The Chevrolet Suburban was discovered Monday by workers pumping water out of the pond and filling it with dirt. The retention pond was surrounded by a fence on city property.
The vehicle was removed with the body still inside. Police are awaiting a search warrant to further examine the vehicle.
