The estranged wife of a Wisconsin man who barged into a Wisconsin spa and allegedly shot seven women before killing himself is among the three women who were fatally wounded.
Zina Haughton died after husband Radcliffe Haughton, 45, allegedly opened fire at the Azana Salon & Spa in Brookfield, Wis., Sunday, a source with knowledge of the investigation said. Police have yet to confirm the identities of the three women killed.
Police were called to the spa several weeks before the shooting because Haughton allegedly slashed the tires of his wife's car. He was arrested and charged for the incident, and later ordered to turn over all guns in his possession to the sheriff's department.
Zina Haughton sought a restraining order on her husband Oct. 8 and a judge issued a four-year restraining order Thursday, according to Brookfield Police Chief Daniel Tushaus.
Investigators say they are still unclear why Radcliffe Haughton allegedly snapped, although they say he and his wife had been estranged for some time.
Witnesses say Zina Haughton's daughter, Yasmeen Daniel, 20, also worked in the spa and witnessed the shooting.
"She had said her stepfather was in there trying to shoot as many people as he could," said Sallie Konruff, a witness at the scene.
Zina and Radcliffe Haughton have a 13-year-old daughter together, who was living with her father until the shooting, the source said.
Radcliffe Haughton's father, Radcliffe Haughton Sr., apologized to the victims and their families for his son's apparent actions shortly after the incident.
"All I can say is, I want to apologize to the people of Milwaukee who have been hurt. He did not give me any hint of what he would do," Haughton told ABC News affiliate WISN-TV.
Haughton Sr., who lives in Florida, told WISN that his son was a former Marine whom he had not seen since sometime last year but spoke to him on the phone from time to time.
The shooting erupted 11:09 a.m. local time in Brookfield, and shortly after SWAT teams surrounded the spa with their guns drawn, preparing for a gun battle.
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.
Customers -- some still in robes, others barefoot -- ran out of the spa in a panic. John Gosh came face-to-face with the shooter as he tried to escape.
"When the suspect came around the corner, he really looked like a deer in headlights. He didn't expect us to be standing there. He just ducked behind the building," Gosh said.
Chief Tushaus said police rescued up to 12 clients and employees when they first arrived and began a painstaking search of the 9,000-square-foot building that includes two floors. The chief said the building included many treatment rooms, often locked.
"We were expecting an armed encounter," Tushaus said.
They found Haughton in a locked section of the building where he had apparently shot himself, the chief said. The four injured women ranged in age from 22 to 40 and were taken to Froedert Hospital with what were described as non-critical injuries.
The hospital was briefly placed on lock down and only patients with a police escort were being accepted. Employees wishing to enter had to show identification.
Sheriff deputies searched the hospital before lifting the lockdown, apparently worried that the gunman had followed the victims to the hospital.
A "be on the lookout" alert was issued for Haughton and hours later, a black 2003 Mazda driven by the suspect was recovered outside of Brookfield, but police declined to say where it was found.
Tushaus said police believe the gunman took a taxi to the spa.
Authorities swarmed Haughton's home in the suburb of Brown Deer, and sent in a robot to search the residence, ABC News' affiliate WISN reported.
The Westmoor Country Club, which shares a parking lot with the spa, was put on lockdown along with other businesses in the area, the club's chief operating officer, Joe Coen, said.
"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."
Wisconsin 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.
Wade Michael Page, an Army veteran and white supremacist, killed six people and injured three others Aug. 5 before fatally shooting himself at a Sikh temple south of Milwaukee.
Less than a mile away, in 2005, 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.
