[At first a clear case: homicide by injury to the neck].

Reported is of a 33 year old female found dead in the basement of her home, manifesting strangulation/throttling marks on the neck. The attack on the throat was, however, not cause of death but a CO intoxication. This woman was killed by direct inhalation of 99% carbon monoxid administered by her husband (via a mask or hose). The carbon monoxid was obtained from a gas cylinder normally used for medical purposes.
