CBI Statement on John Doe
Body was found in the sleeper cab of a deserted semi-trailer truck which had been sitting in an industrial part of north Ft. Collins. Autopsy revealed no evidence of trauma or foul play; the bondage and partial undress of the deceased suggests some sort of sexual game was going on when he expired. It is theorized that death may have been due to a cardiac electromechanical event, perhaps as the result of using some illicit inhalant, such as amyl nitrate. The overall appearance of the deceased suggests he may have been homosexual. The manner of death cannot exclude homicide, natural, or accidental causes. *Height is an estimate. If anyone has any additional information please contact the Larimer County Sheriff Office.
Amyl Nitrate
According to the Alcohol and Drug Federation, Amyl Nitrite is a depressant which slows down the messages travelling between the brain and body. It’s classified as an inhalant, and it belongs to a class of drugs known as alkyl nitrites.
Amyl Nitrite is a vasodilator which is a medicine that causes the blood vessels in the body to dilate, and involuntarily relax the muscles, lowering the blood pressure.
It’s not known if our John Doe inhaled this himself, or had been forced to inhale it by the perpator.
