Michael Mattioli, MPD officer accused of homicide, bound over for trial

Online court records show Officer Michael Mattioli had a preliminary hearing Monday morning, Aug. 31, where a judge bound him over for trial. 

Mattioli was off-duty back in April when investigators say he put Joel Acevedo in a choke hold at his home, killing him. 

Milwaukee police say Mattioli violated the police code of conduct. 

He's also facing a disciplinary trial but remains on paid leave from the department.
