Family files complaint against Wauwatosa police officer involved in three deadly shootings

WAUWATOSA, Wis. (CBS 58) -- Four years after his death, the family of Jay Anderson marched to the Wauwatosa City Hall.

On Thursday, June 18, they filed a formal complaint against Wauwatosa Police Officer Joseph Mensah.

“This will never go away. I’m going to grieve for the rest of my life. And I’ve got to get justice," Jay Anderson, Sr., father of Jay Anderson, Jr., said.

The younger Anderson was asleep inside his car at Madison Park in June 2016 when he was shot by Mensah.

Mensah faced no criminal charges for the deadly shooting.

The Anderson family lawyer also filed several open records requests into the department.

“It can’t be underscored enough that this officer has been working for five years and has fired his weapon 19 times in five years, has killed three people, three men of color within a five-year time period," said attorney Kimberly Motley of Motley Legal Services.

Two other families joined the Anderson’s on Thursday, the loved ones for Alvin Cole, 17, and Antonio Gonzales, 29.

“Everybody is protecting them, but who’s protecting us?” Taleavia Cole, Cole's sister, said.

Mensah was involved in the shooting deaths of both people.

“If we could have got him fired and convicted four years ago that kid would still be living, Alvin Cole would still be living," Linda Anderson, Jay Anderson's mom, said.

For the first time, Antonio Gonzales mom spoke with media.

Mensah was not charged in her son’s case, and she says she wants justice too.

“I don’t know why. I don’t know what has been closed behind closed doors, and I said enough is enough," Sandra Gonzales said.

Officer Mensah is currently on administrative leave pending the outcome of the Alvin Cole case.

Wauwatosa Police told CBS 58 it had no comment on Thursday's filed complaint or march.
