Today we unravel the chilling mystery of the Tylenol murders, a case that forever changed how we trust everyday medicine. In 1982, seven unsuspecting individuals, including Mary Kellerman, Adam Janus, and Paula Prince, tragically lost their lives after ingesting cyanide-laced Tylenol capsules. The ensuing investigation spotlighted James Lewis as a prime suspect, though he was never charged with the murders. Johnson & Johnson's unprecedented recall and introduction of tamper-proof packaging set new standards in product safety. Despite extensive efforts, the perpetrator remains unidentified, leaving a haunting legacy that continues to impact public health policies today.
