The front desk worker said Mangione acted skittish and "cagey" when the suspected CEO killer tried to book a room less than a mile from where he later was arrested.

John Kuklis, a clerk at the Horseshoe Curve Lodge in Altoona, Pa., told ABC News that Mangione, who never pulled his mask down or identified himself at the hotel, was turned away because there were no clean rooms available.

Police in the the Pennsylvania town where Luigi Mangione was arrested claim they’re being threatened by the alleged assassin’s supporters.
