Jury convicts federal inmate for punching and injuring deputy U.S. marshal

"The U.S. Marshals Service is the oldest federal law enforcement agency, and for over 200 years they have performed some of law enforcement's most dangerous work," said Hamdani. "While Walker may have not known that long history, he should have known that striking a DUSM with a closed fist comes with severe consequences and would not go unnoticed. We noticed when we brought this case against Walker and so did 12 of his fellow citizens in handing down today's guilty verdict."

U.S. District Judge George C. Hanks presided over the trial and set sentencing for DATE. At that time, Walker faces up to 20 years in federal prison and a possible $250,000 maximum fine.

He has been and will remain in custody pending sentencing.

The FBI conducted the investigation. Assistant U.S. Attorneys Carrie Wirsing and Anna Swanson are prosecuting the case.
