The Wauwatosa Common Council approved a $95,000 settlement on Tuesday night for Joseph Mensah, the former Wauwatosa police officer who killed three people while on duty during his five years on the force. The settlement stemmed from a workers compensation claim for PTSD.
The city said that Mensah filed the claim a few years ago, Fox6 reported. The money will come through the city’s workers compensation fund. Mayor Dennis McBride said that the settlement was reasonable “to put the matter behind us.”
Attorney Kimberley Motley, who has represented the families of two people killed by Mensah, said that she wasn’t surprised, given Mensah’s history, that he has mental health issues. Motley emphasized that the families of people killed by Mensah had to fight for justice and compensation through the courts, whereas Mensah has received multiple payouts from the city. McBride said that “whatever happened in 2020 or earlier, that’s actually a different matter. So, although I understand the feelings of the Cole family, it’s really an unrelated matter at this point.”
The details of Mensah’s PTSD diagnosis and the work-related trauma that triggered it are not public.
The $95,000 settlement comes on top of $125,000 awarded to Mensah as part of a severance agreement when he left the Wauwatosa Police Department in 2020. As protests mounted against him earlier that year, Mensah also accumulated more than $78,000 in GoFundMe donations. Meanwhile, Mensah remained on paid leave from the police department while the investigation into Cole’s shooting continued. He is also pursuing a separate duty disability claim.
Mensah’s severance agreement included a waiver stating that the city was “irrevocably and unconditionally” released and discharged “from any and all grievances, claims, demands, rights, damages, costs, losses, suits, actions, causes of action, attorney’s fees and expenses of any nature whatsoever …” A city of Wauwatosa spokesperson said in an email to the Wisconsin Examiner that under state law workers compensation is a separate matter and that an employee’s right to pursue workers compensation for a work-related injury cannot be waived or bargained away in a separation agreement.
Mensah’s departure from Wauwatosa amid protests following the killing of George Floyd in Minneapolis. In February of that year, Mensah shot 17-year-old Alvin Cole, his third fatal shooting. Mensah shot Cole during a foot chase as the teen fled Mayfair Mall with his friends after an altercation involving a gun. Mensah said that Cole pointed a gun at him. Witnesses offered conflicting accounts.
Four years earlier in 2016, Mensah killed 25-year-old Jay Anderson Jr. Mensah said that Anderson was sleeping in his car alone in a park late at night, when he awoke and reached for a gun beside him on the passenger seat. Less than a year before killing Anderson, Mensah shot and killed 29-year-old Antonio Gonzales, who was intoxicated and brandishing a sword when officers arrived at his home.
The Milwaukee County District Attorney’s Office declined to charge Mensah after any of the shootings. In 2021, after a John Doe hearing a circuit court judge found that probable cause existed to charge Mensah with homicide by negligent use of a dangerous weapon. Special prosecutors later declined to pursue the charges. In 2025, Mensah testified before the state Legislature in support of a bill prohibiting John Doe hearings for police officers who kill citizens on duty.
Mensah was the target of two federal civil trials brought by the Cole family. Both trials ended in hung juries, and Mensah reached a confidential settlement with the family. Another civil lawsuit involving the Anderson shooting is currently on appeal.
After leaving Wauwatosa, Mensah was hired at the Waukesha County Sheriff’s Department. He resigned as a detective in 2025, between the two Cole trials, and said he was leaving law enforcement altogether. His file from the sheriff’s department states that at times Mensah was congratulated for being professional and compassionate on calls. Other times, supervisors needed to follow up with Mensah for not showing up to court trials, being difficult to reach by phone, missing appointments and not properly analyzing and cataloging evidence. He attempted unsuccessfully to become a drug task force officer. In his employee biography for the sheriffs department, dated January 2021, Mensah said that “the events surrounding my resignation with Wauwatosa PD were unfair, unfortunate, and unjust,” but that he put that chapter behind him.
