DENVER, Jan. 5 (UPI) -- Denver police said a shooting death and a man with a gunshot wound likely are connected and are the result of a medical marijuana sale gone wrong Tuesday.

Officers found an unidentified man shot in the head at a Denver home. The man was pronounced dead at the scene, the Denver Post reported.


Shortly thereafter, another man entered the Denver Health Medical Center for treatment for a gunshot wound, the newspaper said.

Investigators believe the two men were conducting a medical marijuana transaction at the residence when an altercation occurred, Sonny Jackson, a Denver Police Department spokesman, said.

Police are treating the incident as a homicide, and the wounded man is being held as a suspect.
