Carl Buchman was a follower of Abraham Ophion's cult.
Carl, and his wife Simone, were introduced to Abraham when he started working in the Christian Tabernacle of Grace. They found him very intriguing, and soon started believing his alternative ideology.
They took their daughter Janie along with them to the cult, but when she was four years old the Buchman family withdrew from the church. Carl had found Abraham in Janie's room, with him being down to his shorts. After this incident they left Abraham's group.
