Medical examiner: assists law enforcement agencies by providing evidence through forensic science and oversees forensic work. Forensic pathologist: performs autopsies to determine cause and manner of death and sometimes identifies remains. Muscles use atp to pump calcium out of the cell so muscles contract; no more atp=no more contraction=stiff muscles. Begins within 24 hours and disappears within 36 hours.
