Keegan Casteel of Iowa has been charged with two felony counts of unlawful use of weapon. Casteel was arrested earlier this week after he was found in the W Chicago Lakeshore hotel with a .308-caliber rifle with a high-powered scope and laser sight attachment inside a 12th floor room.

Mayor Lori Lightfoot praised the hotel worker who reported Casteel for his quick thinking, “I want to thank the hotel worker who spotted this individual from Iowa who decided it was a good idea to come to our city with an arsenal, an AR-15, and five loaded magazines which he had perched up on the windowsill. Thank God for that hotel worker, who saw something, and said something, and I believe averted disaster,” she said.
