The Order of the Solar Temple was formed in 1984 by Joseph Di Mambro and Luc Jouret. The cult, based on New Age spiritualism, drew followers in Switzerland, France, and Canada.
As the cult became more doomsday focused, it got more followers, who brought in more money.
But in the 1990s, authorities in Canada began investigating the group amid accusations of sexual misconduct, and people started to leave.
