Doc Duncan
Background
Duncan is a semi-retired doctor in Hillsboro, New Mexico. His wife is Dame Alice. Duncan is the leader of a sect of Witches who have gained immortality by transferring their souls into the bodies of children. He murdered his and Alice's child when he found out that she had baptized it in Christianity.
During the events of The Brotherhood of Satan (1971) played by Strother Martin
Doc Duncan gives Mike some pills and Sheriff tells Mike he can't leave town and tells his son Joey to take him home. The Sheriff asks Doc Duncan if he heard that a car made it into town and that Timmy is missing, but his family's car was found crushed. The Witches walk to a dilapidated house and are let inside. They walk into a room and offer a prayer before greeting a large gathering of old people. They reminisce about the last time they were together in France. During the night, The Children walk to the dilapidated house and Doc Duncan lets them inside.
Alice walks into the dilapidated house's worship room and is shunned. She is introduced to Phyllis and Anne shows her the children who are standing on pedestals. Doc Duncan confronts Alice and accuses her of turning her back on their master. She tells him that she has kept the faith and he tells her that he knows that she baptized their child in Christianity. Alice is judged by Satan and found guilty and killed by the other Witches. Doc Duncan walks into the sheriff's office and tells them about the baby that was just born.
K.T. appears at the dilapidated house and joins the other Children in a room. Doc Duncan stands nearby as a robed person brings The Children a cake and The Children play with birthday horns. Later, The Sheriff, Tobey, the Priest, Doc Duncan and Ben and Nicky go to check the residences of what they believe will be the next missing child. The Witches put on robes and chant with Doc Duncan and pray to Satan. Doc Duncan makes all The Witches proclaim their loyalty to Satan once again and they go to their respective alcoves. The children take their place on the 13 pedestals and Doc Duncan prays for Satan to transfer The Witches souls to The Children's bodies. The Witches are all in turn set on fire with burning swords and killed, including Doc Duncan. The Sheriff, Tobey, Ben, and Nicky break open the door to the ritual room and finds a room full of only The Children, including K.T. that just stare at them.
