They aren't sure how many more have been found, since most of them are in pieces.
Matt's father confirmed that they aren't from town, but they can't get a positive ID on any of them. Some of the ten in the trees were indentified as people from all different areas of the state. They hadn't even been reported missing, they were at their houses one moment, here the next. And apparently some had Slenderjunk lying around their houses when the police searched.
The mutilated ones, however, seem to have been killed with a different MO in mind. The only full body, and by full I mean her parts were separated but placed next to each other, had the arms bent at set intervals, with the bones snapped clean to bend.
We found the ///It/// symbol carved into a rock outside our house.
Two intensely terrifying eldritch abominations may or may not have started a turf war in our town.
