A manhunt is underway for the shooter who opened fire Sunday morning inside a Wisconsin spa, killing three and injuring at least four others, police said.
Authorities believe they have found an improvised explosive device inside the Azana Salon and Spa in Brookfield, a suburb of Milwaukee. Bomb units were on the scene. The area, including a nearby shopping mall and country club, were on lockdown.
The identities of the dead and injured were not released. An official at Froedtert Memorial Lutheran Hospital in Milwaukee said four of the injured did not appear to have life-threatening injuries.

Police released the identity of the suspect, Radcliffe Haughton, 45, of Brown Deer. But they gave out little information about him.
"The entire operation is focused on finding him," said Brookfield Police Chief Daniel Tushaus. He asked anyone who sees Haughton to call police.
Tushaus said "the investigation is fluid and ongoing and we have a number of scenes," including the spa, the suspect's house and unspecified others. The spa has not yet been cleared for reentry.
A Froedtert nurse told WISN-TV that police were searching the hospital. The children’s hospital next door was also reportedly on lockdown.
Local television showed police surrounding Haughton’s home in nearby Brown Deer.
Police and emergency vehicles had converged at the Brookfield Square Mall parking lot across the street from the spa.
Leonard Peace, spokesman with the Federal Bureau of Investigation's Milwaukee branch, told the Los Angeles Times that the FBI had sent its SWAT team, hostage negotiators, victim specialists and command staff personnel to support the Brookfield Police Department’s handling of the shooting. He said the shooting was not being treated as a federal crime as of Sunday afternoon.
Two witnesses told television station TMJ-4 that they saw several women run out of the spa shortly after the 11 a.m. shooting, one clenching a towel to her bleeding neck, another holding her arm. The women ran out screaming with their hands up and were immediately taken away from the scene by police, they told the TV station.
The witnesses said numerous police with rifles converged on the scene and locked down the area.
