A man who helped his father behead a 14-year-old girl in Idaho’s wilderness 24 years ago is in custody again, this time for shooting a woman in the head, law enforcement says.

Merritt eventually told police that his father, David, took Benway camping and zip-tied her to a pole inside a tent while he stood outside and chose not to seek help. Merritt told police he participated in order to earn a black rose tattoo, a tattoo for a “brotherhood” of those who have killed people.
