Cook County Sheriff Officer Rafael Munoz sentenced to 1 year in prison for excessive force by U.S. Magistrate Judge Maria Valdez

A federal judge sentenced a former Cook County sheriff's deputy Wednesday to the maximum — one year in prison — for mistreating a shackled detainee by jerking on the chains around his ankles, knocking him to a concrete floor in the department's Maywood lockup and breaking his nose and a tooth.

In handing down the stiffest sentence possible for a misdemeanor conviction, U.S. Magistrate Judge Maria Valdez said she wanted others in law enforcement to know there are consequences for violating the public's trust and that "they have to be careful how they do their jobs."

"The public puts its trust in you as an officer of the law and the incredible power that holds," Valdez told Rafael Munoz. "What happened here was extremely serious."
