The man suspected of shooting up a Wisconsin spa, killing three women and injuring four others, later shot and killed himself, police said.

Authorities spent the afternoon methodically searching the Azana Salon & Spa in Brookfield, Wisc., in a hunt for Radcliffe Haughton, 45. The search of the 9,000 square foot, two story spa was hampered when authorities found what they believed was a bomb.

An urgent manhunt was launched for Haughton, but his body was discovered inside the spa, police said.

"The only individual we were seeking has been found and we believe him to be deceased by a self-inflicted gunshot wound," Brookfield Police spokesman Daniel Tushaus said.

The shooting erupted 11:09 a.m CT in Brookfield, and shortly after SWAT teams surrounded the spa with their guns drawn, preparing for a tactical situation.

Witnesses described screaming women, at least one bleeding, fleeing the spa, with one rolling down a slight hill before police scooped her up and got her out of the area.

A "be on the lookout" alert was issued for Haughton. Hours later, a black 2003 Mazda driven by the suspect was recovered outside of Brookfield, however police declined to say where it was found.

Authorities swarmed Haughton's home in the suburb, Brown Deer, and sent in a robot to search the residence, ABC News' affiliateWISN reported.

Hostage negotiators were on the scene today, however authorities never indicated whether they believed they were dealing with a hostage situation.

The four surviving victims were treated with non-critical injuries at Froedert Hospital. The hospital was briefly placed on lock down and only patients with a police escort are being accepted. Employees wishing to enter must show identification.

Sheriffs deputies searched the hospital before lifting the lockdown, apparently worried that the gunman had followed the victims to the hospital.

The Westmoor Country Club, which shares a parking lot with the spa, has been on lockdown since the incident, said the club's chief operating officer Joe Coen.

"We didn't hear anything but ventured to the north toward the spa and we could clearly see police officers with what looked like to be a rifle and a few attendants were coming out of the building," he said. "We quickly retreated back to the building where authorities have told us to stay."

Gov. Scott Walker pledged his support for the victims and the community.

"Senseless acts of violence leave us with heavy hearts and many questions," Walker said in a statement. "Our state will stand with the victims and their families, and we will provide them with the law enforcement and community support they need to heal in the coming days."

This is not the first time a violent shooting has rocked the area.

On Aug. 5, Wade Michael Page, an Army veteran and white supremacist, killed six people and injured three others before fatally shooting himself at a Sikh temple south of Milwaukee.

In 2005, less than a mile away, a gunman killed seven people and wounded four more at a church service at the Sheraton Hotel. Terry Michael Ratzmann, the 44-year-old gunman, then committed suicide.
