A decapitated body was found on the street Wednesday afternoon in west Dallas, and police are investigating the death, CBS Local reported.

Witnesses said the man wrote a phrase in Spanish on his van before tying one end of a rope around his neck and the other end to a fire hydrant. He then hit the gas in his van, pulling his dead off.

The van did not hurt anyone before it came to a stop on the street. It's not yet known what the man wrote on his van before his death, but authorities believe it may relate to the video game Call of Duty Black Ops, the Daily Mail reported.

After the shocking incident, witnesses posted photos online of what they believed was the victim in the road.

Call of Duty Black Ops is a computer game franchise that releases new games almost every year. It's a first-person shooter that is set in World War II and the Cold War.

In England last year, a coroner said that four teenage who committed suicide were influenced by the game.
