The first rioter to enter the U.S. Capitol building during the Jan. 6, 2021, attack was convicted on Friday of charges that he interfered with police and obstructed Congress from certifying President Joe Biden’s 2020 electoral victory.

Michael Sparks, 46, of Kentucky, jumped through a shattered window moments after another rioter smashed it with a stolen riot shield. Sparks then joined other rioters in chasing a police officer up flights of stairs, one of the most harrowing images from the Jan. 6, 2021, riot.

A federal jury in Washington, D.C., convicted Sparks of all six charges that he faced, including two felonies. Sparks didn’t testify at his weeklong trial. U.S. District Judge Timothy Kelly is scheduled to sentence him on July 9.

Sparks was the “tip of the spear” and breached the Capitol building less than a minute before senators recessed to evacuate the chamber and escape from the mob, Justice Department prosecutor Emily Allen said during the trial’s closing arguments.
