A D.C. Superior Court judge on Monday ordered a Florida man charged with carrying three unregistered guns and ammunition to the U.S. Capitol Building on Sunday to remain in D.C. jail and undergo a 24-hour psychological screening.

Magistrate Judge Michael McCarthy ordered Ty C. Mitchum, 59, of Clearwater, Fla., to remain in D.C. jail after his arrest Sunday for carrying the three guns and ammunition onto the grounds of the Capitol.

In court during the brief hearing, Mitchum, standing next to his court-appointed attorney, seemed disoriented, telling the judge that he had been in jail “three days” and that things were “mixed up.”

Court documents said Mitchum was arrested Sunday outside the Capitol building after police noticed him talking to himself in a restricted area near the building. Police searched him and his vehicle and found the weapons and ammunition. Mitchum told the officers he had two firearms in his vehicle for “protection.”

Police found a Remington 12-gauge shotgun, a 9mm pistol, a Smith & Wesson .38-caliber revolver and 69 rounds of 9mm and 38 rounds of .44-caliber ammunition.

Mitchum pleaded not guilty to three counts of possession of an unregistered firearm and one count of unlawful possession of ammunition. He is scheduled to return to court Tuesday.
