DENVER (CBS4) ― It has the makings of international intrigue. Less than two weeks before the Democratic National Convention a man has been found dead in a Denver hotel room with a container of what authorities initially suspect to be the deadly poison cyanide

Adding to the intrigue is that the dead man, Saleman Abdirahman Dirie, 29, appears to be from outside the U.S. No passport was found on Dirie, who is believed to have entered the country from Canada

A large container of a white powdery substance was found in the man's room on the fourth floor of The Burnsley hotel

It's believed Dirie died from something other than the substance that was in the container.

Denver police are leading the investigation of the man's death. The FBI and other governmental agencies, including the Joint Terrorism Task Force, are assisting in the probe. Hazardous materials assistance has included the Colorado State Patrol and the Colorado National Guard.
