A box of human heads was reported stolen from a truck in Denver, Colorado last week.

The heads were going to be used for medical research when they were stolen. Science Care is a program that facilitates the donation of bodies to medical and scientific research.

The craniums were kept in blue and white boxes labeled "Exempt Human Specimen" and were taken from a transport truck with a dolly.

One Denver resident told KDVR-TV that it was pretty shocking.

The gruesome theft has not resulted in an arrest. The Denver police are investigating. If anyone finds the heads or the boxes, they should contact the cops.

There is a chance that the heads were taken without the thieves realizing what they were stealing.

Maybe there is a mad scientist who is stealing human heads for experiments. If you find a box of human heads, be sure to report it to the police.
