Police in Florida are trying to solve a mystery surrounding a man arrested with a enormous stash of fake military, law enforcement and medical paraphernalia including federal badges, police radios and even a full NASA flight suit and helmet.

In all, Roy Antigua had about 200 suspicious items when he was arrested earlier this month, said James Steffens, chief of the New Port Richey Police Department.

The cache found in Antigua's two homes and Cadillac Escalade included diplomatic license plates, dozens of fake identification cards from the Department of Homeland Security, Immigration and Customs Enforcement, Department of Defense, CIA and NASA. The suspect also had access badges to hospitals around Florida, doctor and nurse scrubs, a respiratory technician badge, police blue lights and access stickers to Coast Guard bases around Florida, Steffens said.

Authorities are wondering if Antigua, 52, was a frequent guest at costume parties or if he was hatching something sinister.
