The Chicago Tylenol Murders is one of the few true crime stories to spark real change in the country. The quality control of pharmaceuticals increased tenfold, as did the security of their packaging. Although the FBI didn’t have enough evidence to convict anyone of the crime, it is widely believed that James William Lewis and his wife were indeed responsible. 

The Girl Scout Murders

Three young Girl Scouts who were camping in Oklahoma during the summer of 1977 were raped and killed. The three girls, Lori, Michelle, and Doris, ranged in age from eight to ten. A camp counsellor discovered a troubling note in her baggage around two months before the murders. The assailant made a promise to kill three campers. The camp counsellor brushed off the menacing note as nothing more than a practical joke because she was aware that young campers love to tell scary stories around the campfire—a judgement she would later come to regret.

The bodies of the girls were discovered in their sleeping bags on the trail leading to the camp showers on June 13 early in the morning. The only things their murderer left behind were a bloody footprint and a red flashlight.

The prime suspect in the Oklahoma Girl Scout Murders was Gene Leroy Hart, an escaped convict. Hart had been raised about a mile from Camp Scott and at the time of the murders he was at large after escaping from prison, where he had been serving time for burglary, kidnapping, and rape. A local jury acquitted Hart of the crime, citing a lack of evidence. However, Oklahoma police consider the case solved.
