Remember your Chemistry classes?

Salt Lake County homicide detective Todd Park was in Reno, Nevada, for a conference about serial killers in 2007 when he first heard about what he calls “the isotope stuff.” A colleague at the meeting described the forensic potential of isotope research being done by IsoForensics, a Salt Lake City company, and Park quickly realized that the science might help identify the victim in a homicide case he had worked on seven years earlier.
