Marrilynn claims that starting at the age of 4, she was sexually abused. The young woman, who grew up as a member of the Fundamentalist Church of Jesus Christ of Latter-Day Saints, says, “Many times, I was told this is what God wanted and, ‘If you had been more obedient and more submissive, it wouldn’t happen.’”

Marrilynn also claims she was physically abused. “I thought that the physical abuse was pretty normal. That’s how everybody grew up,” she says. “If we did not do what we were told, we were beaten with a belt. If you didn’t obey an order that was given, you would get the broomstick.”
