KANSAS CITY, MO—Tammy Dickinson, United States Attorney for the Western District of Missouri, announced that a Kansas City, Mo., man previously charged in federal court with throwing Molotov cocktails at the local congressional office of U.S. Rep. Emanuel Cleaver II was indicted by a federal grand jury today on additional charges.

Eric G. King, 28, of Kansas City, was charged in a four-count indictment returned by a federal grand jury in Kansas City, Mo. Today’s indictment replaces a federal criminal complaint that was filed against King on Sept. 17, 2014.

Today’s indictment contains the original charge against King of using a dangerous instrument to forcibly intimidate and interfere with a federal official engaged in the performance of his official duties. The indictment also charges King with one count of attempted arson for attempting to damage or destroy the building, one count of using explosive materials to commit a felony (arson) and one count of illegally possessing an incendiary device.

On Sept. 11, 2014, at 2:52 a.m., a window was broken and two Molotov cocktails were thrown at Cleaver’s congressional office located at 101 W. 31st Street, Kansas City, Mo. The office was unoccupied at the time of the incident. A hammer used to break the window was recovered from the scene, as well as two broken Molotov cocktails. There was not any fire damage done to the building.

According to an affidavit filed in support of the original criminal complaint, video footage shows King retrieve two bottles with a white ignition source from his backpack, then walk around the parking lot for a few minutes in an effort to hide from cars that were passing by. The footage allegedly shows King throwing a hammer through the west window and lighting the devices. The first device thrown appears to bounce off the side of the building. The second device is ignited and is thrown at the window. King allegedly sprints away from the office.

King was arrested as he was leaving his apartment on Sept. 16, 2014.

Dickinson cautioned that the charges contained in this indictment are simply accusations, and not evidence of guilt. Evidence supporting the charges must be presented to a federal trial jury, whose duty is to determine guilt or innocence.

This case is being prosecuted by Assistant U.S. Attorney Patrick C. Edwards. It was investigated by the FBI and the Kansas City, Mo., Police Department, the Federal Protective Service and the Bureau of Alcohol, Tobacco, Firearms and Explosives.
