BROOKFIELD , Wis. (CBS/AP) -- Deputies searched Sunday for a shooter after multiple people were wounded when someone opened fire at a spa near a suburban Milwaukee shopping mall.
Police in Wisconsin say three people have been killed and four wounded in a shooting at a spa outside of Milwaukee, according to the Associated Press.
The shooting occurred about 11 a.m. Sunday at the Azana Day Spa, a two-story, 9,000-square-foot building across the street from the Brookfield Square Mall in a middle- to upper-class community west of Milwaukee.
Froedtert Hospital has told CBS News that four non-critical patients have already arrived.
The mall and a county club adjacent to the spa were locked down, local media reported, and the bomb squad is on the scene.
CBS Affiliate WDJT is reporting that Froedtert Hospital is also on lockdown.
The Waukesha County Sheriff's Department said they are looking for the shooter. Police describe the suspect as a male, 6'2" tall, with dark skin. Law enforcement officials told WDJT that contrary to previous reports, the suspect is not African American.
He may be wearing a grey sweater, blue jeans, carrying a white and black backpack, and driving a black 2003 Mazda.
Milwaukee FBI spokesman Leonard Peace said its SWAT team, hostage negotiators and others were helping with the response. But he declined to say how many FBI personnel were involved in all or provide details on what had happened.
Robert Schmidt, spokesman for the Bureau of Alcohol, Tobacco, Firearms and Explosives, said it had 10 agents participating.
Beth Strohbusch, a spokeswoman for Froedtert Memorial Hospital, said four shooting victims were taken there, and three more were expected. She said none of the four already received were in critical condition.
Tactical teams were on the scene, along with at least 20 fire, ambulance and police vehicles. A medical helicopter was on the ground.
It was the second mass shooting in Wisconsin this year. Wade Michael Page, a 40-year-old Army veteran and white supremacist, killed six people and injured three others before fatally shooting himself Aug. 5 at a Sikh temple south of Milwaukee.
The shooting at the mall took place less than a mile from where seven people were killed and four wounded on March 12, 2005, when a gunman opened fire at a Living Church of God service held at a hotel.
