The first rioter to breach the U.S. Capitol on Jan. 6, 2021, was sentenced Tuesday to more than four years in prison, federal prosecutors announced.

In March, a federal jury found Michael Sparks, 47, of Elizabethtown, Ky., guilty on felony charges of obstructing an official proceeding and civil disorder and several misdemeanor charges for being on the premises of the Capitol building on Jan. 6.

On Tuesday, Judge Timothy J. Kelly of U.S. District Court in Washington sentenced him to 53 months in prison and ordered him to pay a $2,000 fine. Mr. Sparks will be on supervised release for three years after his prison term ends, prosecutors said.

Video footage presented in court showed that Mr. Sparks entering the Capitol building at 2:13 p.m. on Jan. 6 through a window near a door leading into the Senate Wing that rioters had smashed with a police shield.

Mr. Sparks was among the initial group of rioters who were confronted by Eugene Goodman, a Capitol Police officer, who helped hold off the mob from reaching members of Congress.

The rioters chased Mr. Goodman up a flight of stairs as they demanded to know where Congress was certifying the results of the election, prosecutors said.
