Police are looking for a white male suspect in his 20s or 30s after seven adults and one teenager were injured in a shooting at Mayfair Mall Friday, according to Wauwatosa Police Chief Barry Weber.
In a statement, the police department said officers were called to the northwest entrance of Macy's at about 2:50 p.m. Friday. When police arrived, the shooter was no longer on the scene.
As of 9:30 p.m., Wauwatosa police said in a tweet that authorities still had not identified or arrested the suspect. But in the latest update, the department offered its first explanation of what may have led to the shooting.
“Preliminary investigation has led us to believe that this shooting was not a random act, and was the result of an altercation,” said police, who added that the mall was now cleared and secure.
Authorities said the mall will be closed Saturday and investigators will remain there overnight.
Law enforcement from "numerous agencies" were called in to help clear the mall Friday, according to Wauwatosa Police. Heavily armed FBI personnel were also spotted at the mall.
On Friday, Weber said people looking to reunite with family members who were in the mall at the time of the shooting should go to the At Home store at 3201 N. Mayfair Road, which was being used as a reunification area.
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.
