Suicidal asphyxiation by carbon monoxide within a polythene bag

Abstract

Suicide by inhalation of carbon monoxide is not uncommon and usually involves car exhausts or burning charcoal or defective boilers. We report a case of a 25-year-old man, who committed suicide by inhaling carbon monoxide gas inside a polythene bag in a bathroom. The open carbon monoxide cylinder found inside the polythene bag was purchased online by the deceased a few days earlier. He had stated that the gas would be used for his experiment on the environment. A suicide note recovered from his trouser pocket revealed his intention for a painless death.
