MADISON, Wis. — An oversight board demoted Milwaukee Police Chief Alfonso Morales after questioning how he handled multiple incidents, including ordering officers to fire tear gas and pepper spray at protesters demonstrating over George Floyd’s death.

The city’s Fire and Police Commission unanimously voted Thursday evening to demote Morales to captain after 3½ years on the job.

The chief’s attorney, Franklyn Gimbel, said Morales’ relationship with the commission has been deteriorating since he refused the chairman’s demand to fire an officer involved in the arrest of Milwaukee Bucks player Sterling Brown in January 2018. Most recently the commission criticized Morales for authorizing tear gas to disperse protesters. The board has also raised questions about how the department has policed Black communities.

Morales joined the Milwaukee department in 1993 and was appointed chief in February 2018.

“His conduct is unbecoming, filled with ethical lapses and flawed decisions, making it inconsistent with someone who has the privilege of leading the Milwaukee Police Department,” Commissioner Raymond Robakowski said.

The board named Assistant Police Chief Michael J. Brunson Sr. as acting chief.

Milwaukee Mayor Tom Barrett said Thursday night he was angered by the commission's action and that Morales should have been given a chance to respond to directives the panel had issued.

“The discussion surrounding this decision tonight was completely lacking in transparency. The action taken by the commission tonight was not good government,” Barrett said.

The decision comes as Wisconsin's largest police department grapples with a surge in gun violence and plans security for a scaled-down Democratic National Convention.

A number of police chiefs across the country have left their jobs as pressure mounts to rethink American policing following Floyd’s death, including Erika Shields in Atlanta, Jami Resch in Portland, Oregon, and William Smith in Richmond, Virginia.

Milwaukee’s mayor had urged the commission to slow down, but Gimbel said the odds appeared to be stacked against the chief.

“I’m unaware of him having any supporters (on the commission),” Gimbel, said. “There seems like a cumulative sense that they want to dump the guy.”

Gimbel declined comment to The Associated Press after the meeting.

Morales is Latino, and the majority of the commissioners are Black. His relationship with the board has deteriorated since it named him to the post in February 2018.

Gimbel said problems began when officers arrested Brown for parking illegally in January 2018. Officers swarmed the Bucks guard and used a stun gun on him when he didn't remove his hands from his pockets. The commission's chairman, Steven DeVougas, who is Black, told Morales to fire one of the officers involved but Morales refused, the attorney said.

“From there, it got stressful,” Gimbel said. “DeVougas viewed him as not being a team player.”

In February, the Milwaukee Police Association, which represents rank-and-file officers, filed an ethics complaint against DeVougas alleging he accompanied a real estate developer during an interview with police who suspected the developer of sexual assault. DeVougas practices real estate law for the developer's business. The police association argued DeVougas' presence during the interview was a misuse of his position as commission chairman. A city ethics board is investigating.

Fast forward to May and June, when Milwaukee police used tear gas and pepper spray to disperse protesters demonstrating over Floyd’s death. Floyd, who was Black, died on Memorial Day in Minneapolis after a police officer pressed his knee into his neck for nearly eight minutes.

The decision to use tear gas and pepper spray drew criticism from Barrett. The commission in July banned the police department from using tear gas, prompting a number of departments from across the state slated to help with convention security to rescind their support.
