Shafer is considered a “prophet” of the cult and reportedly intended to marry the Coltharp sisters, according to law enforcement.

According to the Daily Mail, Shafer's own daughters, Lily and Samantha, ages 7 and 5, were also found during the police raid. They were reportedly not reported missing.

Authorities claimed the men's religious fanaticism centered on apocalyptic beliefs and the prospect of gaining followers, the Daily Mail reported. Schaefer's cult, known as the “Knights of the Crystal Blade,” spread his disturbing teachings, the paper said. Schafer reportedly detailed on his website his own “revelations” about marriage and cheating, including controversial practices such as polygamy and child marriage.
