WASHINGTON — A member of the mob that launched a series of violent attacks on police — including Washington, D.C., officer Michael Fanone — in a tunnel under the U.S. Capitol on Jan. 6, 2021, apologized Tuesday as a judge sentenced him to seven years and two months in prison.

Kyle Young, 38, is the first rioter to be sentenced for the group attack on Fanone, who was dragged into the mob, beaten and electrocuted until he suffered a heart attack and lost consciousness.

"You were a one-man wrecking ball that day," Judge Amy Berman Jackson said. "You were the violence."

Fanone resigned from the Washington, D.C., police late last year, saying fellow officers turned on him for speaking so publicly about the Capitol attack and former president Donald Trump's role in it. In court Tuesday, Fanone confronted his attacker directly, telling Young, "I hope you suffer."

"The assault on me by Mr. Young cost me my career," Fanone said. "It cost me my faith in law enforcement and many of the institutions I dedicated two decades of my life to serving."

Young pleaded guilty in May to being in the group that attacked Fanone. Documents filed with his plea agreement offer this account:

Young and his 16-year-old son joined the tunnel battle just before 3 p.m., and Young handed a stun gun to another rioter and showed him how to use it. When Fanone was pulled from the police line, Young and his son pushed through the crowd toward him.

Just after that, authorities said, another rioter repeatedly shocked Fanone with the stun gun, and Young helped restrain the officer as another rioter stole his badge and radio.

Young lost his grip on Fanone as the mob moved. He then pushed and hit a nearby Capitol police officer, who had just been struck with bear spray, according to documents filed with his plea.

Young also pointed a strobe light at the officers, jabbed at them with a stick and threw an audio speaker toward the police line, hitting another rioter in the back of the head, prosecutors said.

In a letter to the court, Young said he cried on the phone with his wife as he left Washington.

"I was a nervous wreck and highly ashamed of myself," he wrote. "I do not condone this and do not promote this like others have done. Violence isn't the answer."

In court, he apologized to Fanone, saying, "I hope someday you forgive me. . . . I am so, so sorry. If I could take it back, I would."

Young has a long criminal history. While in prison for producing meth, he was repeatedly sanctioned for violence. His attorney said that after a difficult childhood, Young had straightened out his life, gotten married, raised four children and started working in HVAC installation. Until Jan. 6, he hadn't been arrested in a dozen years, his attorney said.

His "conduct on January 6 is isolated to a unique set of circumstances that unfolded that are not likely to be replicated," wrote his attorney, Samuel Moore.

Jackson said she believed Young had become a good husband and father. But she noted the continued possibility of political violence, with Trump and his allies responding to possible prosecution by "cagily predicting or even outright calling for violence in the streets."

The sentence she gave Young is close to the eight-year statutory maximum for assaulting a police officer.

Two of the other men accused of involvement in the attack on Fanone have pleaded not guilty. One has admitted dragging Fanone down the Capitol steps; he is set to be sentenced in October.
