The Chicago Tylenol murders were a series of unsolved murders in Chicago that resulted in the creation of the tamper proof seal on medication. 7 people died as a result of Tylenol that had been laced with cyanide.
When Adam Janus took a dose of extra strength Tylenol he fill ill and was immediately rushed to the hospital where he died. His brother Stanley and sister in law Theresa went home and each took a Tylenol and both died as a result of cyanide poisoning. It was only when comparing the bottles from the Janus and Kellerman murders that a connection was discovered. They had the same control number, MC2880. The Medical examiner told the leading officer to smell the bottles. The bottle smelled like almonds, leading the ME to assume cyanide was the culprit as cyanide is said to smell like almonds.
Over 31 million bottles of Tylenol were recalled. This caused Johnson & Johnson, the makers of Tylenol, to put up a $100,000 reward for any information about the person who had done this.
It has never been discovered who took these seven lives though some suspect the unabomber, Ted Kaczynski, was smart enough to do this. We may never know who took these seven lives or why but some good di come of this. The tamper proof seal one now finds on medication was introduced to keep people from meeting the same fate as they could now tell if anyone had tampered with their medication before them.
