Ex-Milwaukee Officer Who Aided Gang, Shared Police Intel Is Sentenced

MILWAUKEE, WI — A former Milwaukee police officer who admitted to helping a violent street gang and betraying his fellow officers has been sentenced to five years in federal prison, according to the U.S. Attorney’s Office.

Juwon Madlock, 30, was sentenced March 24 by Brett H. Ludwig to five years in prison, followed by three years of supervised release.

Prosecutors said Madlock engaged in a wide range of criminal conduct while serving as a police officer. According to court documents, he provided ammunition to a felon, possessed an automatic weapon, helped a street gang hide stolen vehicles and lied to the FBI.

Authorities said Madlock’s actions went even further. He sent photos of fellow officers to a gang member, offered to sell rifles and advised wanted criminals on how to avoid law enforcement.

Most seriously, prosecutors said Madlock told a violent gang where to find its rivals, knowing the information could be used to carry out shootings.

In court, prosecutors argued a significant sentence was necessary, writing that Madlock “knew what he was doing, and he knew it was wrong,” but chose to “imperil the public, betray his colleagues, and violate his oath.”

Judge Ludwig called the case “tragic” and “sad,” noting Madlock had multiple opportunities to stop but continued his conduct. The judge also said Madlock was “lucky” no one was killed, adding that he could have been considered “party to a murder” if violence had occurred.

Brad D. Schimel said the case represented a serious breach of public trust.

“The defendant used his position as a police officer to provide information to gang members to assist them in perpetrating crimes against the very community he swore to protect and serve,” Schimel said. “For a sworn officer to traffic in law enforcement sensitive information, weapons and drugs while on duty is simply unconscionable, and he belongs in prison.”

Alan Karr called Madlock’s actions a “reprehensible” betrayal of trust and said investigators will continue to pursue those who assist criminal organizations.

Milwaukee Police Chief Jeffrey Norman said the department supports holding officers accountable when they break the law.

“No one is above the law,” Norman said.

Madlock pleaded guilty to charges related to the misconduct in December 2025. The case was investigated by the FBI and Milwaukee Police Department.
