Mummified cadaver of suicide by hanging
On the other end of the scale from that rapid putrefaction is mummification.
This cadaver is of a man who hanged himself in a dry, airy attic ten years before being found. His organs began to putrefy shortly after death, but as he disappeared (and likely hanged himself shortly after) in mid-November, the dry, cold, winter air halted to decomposition process. As he dessicated all winter long, the heat and insect activity of the following summers had little effect on his remains. Since the area he was found had little humidity during the summer, it appears that the heat hardened the remaining skin, and did not allow further decomposition as it would have when coupled with dampness.
