The group had its roots back in the '70s when a Texas music teacher named Marshall Applewhite lost his job after having an inappropriate relationship with a male student, according to Rolling Stone. Not long afterward, he met a nurse named Bonnie Nettles. Both had an interest in biblical prophecy, and Applewhite believed the two shared a bond because they'd met in a previous life.
For her part, Nettles told Applewhite that she knew they'd meet someday ... because extraterrestrials had preordained their encounter.
Together, the two blended multiple religious teachings from the New Testament with various bits of eschatology, mysticism, astrology, asceticism, reincarnation and science fiction, as well as aspects of Applewhite's Presbyterian upbringing. All of this was a result of Nettles' belief that a monk from the 1800s often had conversations with her, providing life guidance.
The two didn't have a romantic relationship. Instead, they bonded in their efforts to ascend to a higher existence and ultimately reach the kingdom of heaven. Applewhite began calling himself "Do," and Nettles became "Ti." Sometimes they called themselves "Bo" and "Peep."
In the mid-1970s, they persuaded a group of 20 Oregonians to leave behind their families, lives and worldly possessions for Colorado. There, they waited for an alien spaceship to arrive. It never did, so the group began dwindling.
In 1985, Nettles died from cancer, leaving Applewhite depressed. But he remained undeterred.
By the early 1990s, he'd tweaked his beliefs and started recruiting new members to the UFO religion. The group bounced from place to place, sometimes living in campgrounds around the country, occasionally panhandling and always looking to recruit new converts, reported The New York Times.
