Homicide by methane gas

Two cases of sudden death due to myocardial infarction which were associated external injuries on the chest are discussed here. Injuries were in the form of abraded contusions on the anterior part of chest. Both the cases were declared dead on arrival to the casualty section (Accident and Emergencies Department). In these cases, mention of injuries was not made in the inquest report. In both the cases, suspicion of foul play or the trauma induced myocardial infarction were ruled out by inquiring into the incidents by the autopsy surgeon. The cases highlight the importance of detailed history by the autopsy surgeon in cases of sudden death with associated injuries on the front of the chest.
