A civil rights lawsuit against a former Milwaukee police officer involved in the 2020 death of Joel Acevedo was dismissed by a federal judge.
Judge Brett Ludwig signed the order March 6, ruling that neither the officer, Michael Mattioli, nor the city of Milwaukee owes damages to Acevedo’s family. The decision comes after Mattioli was previously found not guilty of homicide in the incident.
Lawyers representing Acevedo’s estate and his brother did not immediately respond to WPR’s request for comment.
The lawsuit stems from an altercation that took place at Mattioli’s home in the early morning of April 19, 2020.
The off-duty Milwaukee officer woke up and found Acevedo, his friend, digging through his pants pockets, Mattioli told Milwaukee County District Attorney Investigator David Dalland. It was after a night of drinking. The confrontation that followed led to Mattioli putting Acevedo in a rear-naked chokehold for more than 11 minutes.
Acevedo died of his injuries nearly five days later. He was 25 years old.
The next month Mattioli was charged with first-degree reckless homicide. A jury found him not guilty in 2023.
At the time, Mattioli said he was not trying to “hurt the guy or kill the guy. … He was trying to ‘arrest’ the guy,” according to court documents.
Mattioli’s lawyers did not immediately respond to WPR’s request for a comment.
The suit argued that Mattioli “used deadly force” despite knowing Acevedo “did not present as a serious or deadly threat.” The document claimed the actions violated Acevedo’s civil rights.
His family was seeking compensatory damages, punitive damages, equitable relief, attorney costs and discretionary relief.
Lawsuit dismissed in choking death involving former Milwaukee police officer was originally published by Wisconsin Public Radio.
