A body is found with only the skin on the arms missing; the rest of the skin is present and black in color. The bones of the arms appear greasy, and maggots are eating at remains of the internal organs. If it were found in a hot, arid place, what stage of decomposition would the remains indicate and what is the most likely PMI? If a local person matching the description of the remains has been missing 1 year, could this body be his?
