The girl was found dead at the family home on Dec. 20. Knox said she had been severely beaten and dunked in an icy pond as part of what appeared to be a “religious-type episode.”
Across-the-road neighbors Ethan Mast, 35, and Kourtney Aumen, 21, were charged last week with second-degree murder and other offenses. Both are jailed without bond. Ethan Mast is not believed to be related to James and Mary Mast, Knox said.
Both families attend the same church, but Knox said that the actions involving the girl are not condoned by the church, which he declined to name.
“The investigation done so far indicates that this is an isolated incident and NOT the actions of a cult,” Knox wrote in a news release on the department's Facebook page.
