PHOENIX—Sam Kazemi stood over the old man’s corpse. Nearby lay pliers, a scalpel and a motorized saw designed to cut drywall and pipe.
On a busy day, Kazemi might harvest body parts from five or six people who had donated their bodies to science. On this day in November 2013, the corpse before Kazemi typified the donors who gave their remains to his employer, Biological Resource Center.
