ST. LOUIS • A 33-year-old Fairview Heights man who had been asked to stay away from a U.S. Army recruiting office there was accused Tuesday of firebombing the Robert A. Young Federal Building in downtown St. Louis Monday.

Federal prosecutors in St. Louis said that Jeremiah Merello McGee, 33, used a Starbucks Mocha Frappuchino bottle to attack the building just after 1 a.m., throwing the bottle against the northwest corner of the building and triggering a flash and flames. The side of the building and sidewalk were scorched by the contents of the bottle, but no one was injured.

Prosecutors say that McGee parked his car near a guard shack on the north side of the building, which is located at 1222 Spruce Street, then walked towards the building. He returned to his car, retrieved an object, lit it and threw it as a guard watched, according to an affidavit filed in court by FBI Special Agent Dan McCarthy.

Police found pieces of a broken bottle at the scene and a tip from an employee of the recruiting office led investigators to McGee, McCarthy wrote.

McGee had been asked to leave the Fairview Heights recruiting station on April 13. he had been there before, each time mumbling “about the army and the government 'getting up in his house,'” McCarthy wrote.

McGee was charged Tuesday with attempted destruction of U.S. property by fire or explosion, a charge carrying a potential penalty of five to 20 years in prison.

In addition to police, the FBI, the Federal Protective Service and the Department of Homeland Security investigated the incident.
