The post mortem interval was estimated by indirect clues.
Twenty mummies discovered in a forensic context between 2002 and 2016 were compiled in this work. 15 cases were excluded and 15 cases of forensic mummies were found in the literature. In the current work the percentage of mummification was calculated by “the rule of nines” used for describing burned injuries in livings. Dry and hot environments, emaciation, little access to flies are favorable conditions for mummification. Nevertheless mummification was also observed in other cold and humid environments. Extensive mummification (defined in this work as “at least 50% of mummification of the body skin) has occurred in as little as three weeks in the current series. The post mortem interval was estimated by indirect clues. The cause of death was usually impossible to establish.
