After ordering her parents to sexually assault her in Lincoln, Missouri, neighbors have reportedly killed 4-year-old girl, Jessica Mast.

On an allegation that she was demon-possessed, the neighbors, Ethan Mast and his girlfriend Kourtney Aumen had ordered Jessica’s parents, James and Mary Mast, to have their daughter beaten.

Ethan and Aumen beat the 4-year-old with a wooden spoon and threatened to kill her parents if they tried to stop them.

They forced the parents to sexually assault Jessica whom they also beat with a belt before dunking her in a freezing lake.

Jessica’s younger brother was not spared from the beating except her youngest sibling, a baby, who was not harmed during the incident.

When James was asked why he allowed his daughter to be treated in that manner, he repeated the demon-possession line. He also said Ethan and Aumen told him that Mary would have been possessed too had it been Jessica wasn’t killed.

Ethan Mast and Aumen were arrested on December 21 and charged with second-degree murder.
