Started out with the three folks....husband and wife, with a 2nd lady. Checked into the hotel, seemed to be ok, and the maid found all three dead the next day. Husband and wife were dead in the bed, arrow shot in each head. Second lady was dead on the floor, arrow shot as well.
So cops went to the home of single lady, and found two more folks dead (didn’t say if they were arrow shots or not). No robbery demonstrated. Might have been kind of cult deal or possibly all in some doom episode. Just is odd that a crossbow was the weapon of choice, but you can still buy them without a license.
Man with beard. Women dressed in black.
Germans don’t have cults. Unless you count that guy named Hitler.
