A case of homicidal choking mistaken for suicide

This report presents an autopsy case of the homicidal choking of an adult, who died as a result of tissue paper being thrust into his mouth. An in-patient (a 29-year-old Japanese man) at a mental hospital was choked to death by another male in-patient, his roommate, who thrust a large amount of tissue paper into his mouth after rendering him slightly unconscious by cervical compression. At the time of discovery, this mental patient was believed to have committed suicide by inserting tissue paper into his own mouth. Autopsy findings and re-investigation of the case revealed that the subject had been murdered. This is a very rare case of choking used as a method of homicide.
