mbk, when a person dies blowflies and fresh flies are the first carion insects to arrive and seek a suitable oviposition site because the human body or bodies of living organisms begin to decompose shortly after death..as the cells die, bacteria within the body begin breaking them down. Enzymes in the pancreas cause the organ to digest itself. The body soon takes on a gruesome appearance and smell..so it still puzzles me how on earth they did not discover the coarpse of the poor old lady..tsk..
