WAUWATOSA, Wis. — A shooting at a mall in a suburb of Milwaukee left multiple people with non-life-threatening injuries Friday, according to the city’s mayor.

Wauwatosa Mayor Dennis McBride said in an afternoon statement that a suspect remained at large after the shooting at Mayfair Mall, where witnesses told WISN-TV that they had heard what they believed to be eight to 12 gunshots.

WISN reported that at least five people were taken away from the mall on stretchers, at least two of whom were sitting upright and appeared to be conscious. Some people remained in the mall while police searched for a suspect. The station interviewed several people outside the mall who said they had friends sheltering in stores inside.

Jill Wooley was inside Macy’s with her 79-year-old mother when they heard eight to 12 gun shots just outside the store entrance.

“We heard the first shot fired and knew immediately it was a gunshot,” Wooley told CBS58 in Milwaukee. “We both just dropped to the floor.”

Wooley said she didn’t see anyone but the shots were “very close.” She added that they ran in the opposite direction to the basement of the store, where they then hid.

Trish Cox’s 19-year-old nephew works at Finish Line sporting goods store. She said she was worried because the store’s phone wasn’t being answered. She was waiting frantically while FBI agents cleared the mall.

An agent who wouldn’t give his name said the mall was being “methodically” cleared. Heavily armed FBI personnel were visible at the mall.

Mall operator Brookfield Properties said in a statement they were “disheartened and angered that our guests and tenants were subject to this violent incident today.” They declined further comment.

The Mayfair Mall was the site of a February shooting in which a city police officer, Joseph Mensah, shot and killed Alvin Cole, a Black 17-year-old. Police said Cole was fleeing from police; Mensah, who is also Black, said he shot Cole because Cole pointed a gun at him. The mall was the target of sporadic protests over several months in the wake of the shooting.

The Milwaukee County district attorney declined to file charges against Mensah, but the city this week agreed to a separation agreement in which Mensah will be paid at least $130,000 to leave the force.
