A gunman opened fire inside a shopping mall near Milwaukee on Friday, leaving seven adults and one teenager injured, police said. The extent of the injuries was unclear.
The suspect, described as a White male in his 20s or 30s, fled the scene before officers arrived at the Mayfair Mall in Wauwatosa. Police Chief Barry Weber said they were working to determine the suspect's identity.
The shooting occurred around 2:50 p.m. Friday, prompting a large police presence of about 75 officers at the scene. The Milwaukee division of the FBI said it was assisting local law enforcement.
Hours after the shooting, Wauwatosa police said a preliminary investigation led investigators to believe that the shooting "was not a random act, and was the result of an altercation." They did not provide more details.
Earlier Friday, Mayor Dennis McBride said the shooter remained at large and that none of the victims' injuries appeared to be life-threatening. McBride called the shooting an "active shooter" incident.
The Mayfair Mall released a statement on the shooting: "We are disheartened and angered that our guests and tenants were subject to this violent incident today. We are thankful for our partners at the Wauwatosa Police Department and we are cooperating with them as their investigation develops."
