Taos Hum
In this small New Mexico town, the same low-frequency buzzing sound has been annoying its residents since the early 1990s. The townspeople complained about the strange sound to Congress in 1993, but despite the numerous studies that have been conducted, scientists have repeatedly come up empty-handed. Almost thirty years later, nobody knows what the noise could possibly be.
The Black Dahlia
In 1947, 22-year-old actress Elizabeth Short was found brutally murdered in a vacant Los Angeles parking lot. Several people took credit for the crime, but none of them were charged. Short was dubbed "Black Dahlia" because she loved black dresses.
