Catching Killers: SEASON 2: EPISODE 6

Cause of Death

When a death looks suspicious, forensic pathologists take a closer look. By thoroughly examining a corpse, they can determine the cause of death and whether or not a crime has taken place. See how this forensic science first gained notoriety 100 years ago in England, when a pathologist, though autopsies and wildly unconventional research methods, linked one man to two suspicious honeymoon deaths. Then, discover how a postmortem examination in Cincinnati in 1987 led detectives to one of the most prolific serial killers in American history.
