The Zodiac Killer
For several decades, the Zodiac Killer terrorized the San Fransisco Bay area, committing at least seven confirmed murders—although he claims to have killed 37. The killer sent taunting messages in code to the police and the newspaper, which offered chilling information about his identity and his victims. "I am not sick," he wrote in one letter. "I am insane." The case remains cold to this day.
Disembodied Feet
On August 20, 2007, a disembodied human foot—still inside an Adidas sneaker—washed up on a beach near Vancouver. A week later, another foot washed ashore, this time clad in a white Reebok. In the years since, a total of thirteen feet, most in sneakers, have appeared on the beaches of British Columbia.
