Walter Collins
In 1928, nine-year-old Walter Collins went to the movies, but he didn't make it home. At the time, the LAPD was dealing with several bizarre disappearances, so when the Illinois police claimed they had located Collins, they turned the boy back over to his mother. She insisted that the boy was not her son, but the police forced her to take him home with her. Later, the boy admitted that he was impersonating her son; the real Walter Collins was never heard from again.
Georgia Guidestones
Also called the "American Stonehenge", this granite monument was constructed in a Georgia field off Highway 77 in 1979. It features ten commandments for "an Age of Reason", written in eight different languages. However, these commandments don't align with the original—one of the controversial carvings reads, "Maintain humanity under 500,000,000 in perpetual balance with nature"—but it is unclear who paid for the construction of the monument, or what it stands for.
