Milwaukee police shared the following statement with FOX6 News on this case:

"In May of 2022, MPD received a citizen complaint alleging that a department member had engaged in criminal misconduct while off duty and at his residence. Due to the nature of the allegation, a criminal investigation was immediately initiated and that member was placed on complete suspension. The investigation was referred to the District Attorney's Office resulting in a criminal complaint and the member being taken into custody. The member has since tendered his resignation to the Milwaukee Police Department."
