For this week’s episode, Jim tells us about a particularly gross and scary individual named Gary Michael Heidnik. Like a lot of “successful” murderers, this guy was very smart. And not just kind of smart, but he actually had a genius level IQ and was a member of MENSA which is basically a club for geniuses. Because of his above average intelligence, Gary was able to carry on with his crimes far longer than a lot of killers because he was always learning as he continued committing his crimes through the years, continually cultivating his skills.
