The Jersey Devil

This was a pretty violent encounter. It sounded like the creatures arm was severed by the window?? No date was given but the author says it was over 6 decades ago so that would be the 1950s, so the window would be manual. I don’t know if that is actually possible. The author said the creature picked up his arm and ran into the woods. I wish the facts of this story were a little more clear. The Pine Barron’s are a hot spot for weird sightings for sure.
