A New Jersey man who attacked Capitol Police Office Brian Sicknick during the Jan. 6, 2021, at the U.S. Capitol riot with a chemical irritant was sentenced Friday to more than six years in prison. 

Julian Khater wasn't charged in the death of Sicknick, who passed away the next day after the siege. 

He read aloud a statement before U.S. District Judge Thomas Hogan in a Washington D.C. courtroom but didn't mention Sicknick or his family. Hogan said Sicknick's death was the "elephant in the room" but stressed that the coroner's report didn't give him any basis to use that as a sentencing factor.

"Somewhere along the line, we've lost the sense of acceptance of responsibility," he said. 

Khater was given credit for two years served in jail and was also ordered to pay a $10,000 fine. Dozens of police officers appeared in court. Sicknick's family said despite Khater and his co-defendant George Tanios weren't charged in his death, they bear responsibility. 

"Your selfish actions have caused more pain than you could ever imagine," said an older brother, Craig Sicknick. "My family is a wreck, and none of us have been even remotely unscathed as the result of your actions that day."

Gladys Sicknick, the officer's mother, told Khater he is "center stage in our recurring nightmare."

"You attacked my son like he was an animal. You are the animal, Mr. Khater," she said.

Tanios previously pleaded guilty to misdemeanor charges of disorderly and disruptive conduct and spent nearly six months in jail before an appeals court ordered his release. He was sentenced Friday to time served. 

Sicknick died from natural causes after suffering two strokes near his brain stem, medical examiner’s office in Washington determined in April 2021. The medical examiner also noted that Sicknick had engaged with rioters on Jan. 6 and that "all that transpired played a role in his condition," according to prosecutors.
