VIDEO: Fired Milwaukee Officer Will Not Be Charged for Killing Mentally Ill Man

Former Milwaukee police officer Christopher Manney will not be charged in connection with the on-duty fatal shooting of Dontre Hamilton at Red Arrow Park, Milwaukee County District Attorney John Chisholm said Monday.

The decision comes nearly eight months after the shooting. Chisholm has said he was waiting on reports from an outside expert on the use of force, the Milwaukee Journal-Sentinel reports.

"This was a tragic incident for the Hamilton family and for the community," Chisholm wrote in his report. "But, based on all the evidence and analysis presented in this report, I come to the conclusion that Officer Manney's use of force in this incident was justified self-defense and that defense cannot be reasonably overcome to establish a basis to charge Officer Manney with a crime."

Manney was fired in October for a violation of Milwaukee PD policy. Chief Ed Flynn said at the time that the shooting was justified but the patdown that preceded the shooting violated policy.

The decision to fire Manney stirred unrest among the department's rank-and-file. Shortly after Manney's firing, the Milwaukee Police Association convened a no-confidence vote. Of the union members who voted, nearly all indicated they had no confidence in Flynn. The union has not disclosed the exact number of voters, but said it was a majority of the roughly 1,600 membership.
