A spokeswoman at Froedtert Hospital, where the injured were taken, said one of the four women was released Monday afternoon. Kathy Sieja said the three other women were in satisfactory condition.
Ernest J. Polk, a neighbor who lives across the street from the Haughtons, said the couple was generally friendly to him but he saw signs of turmoil.
"There was always confrontation over there, but I never thought it would come to this," he said. ". . . It was mostly verbal. I didn't see anything physical."
Customers described Zina Haughton was a popular hair stylist who decorated her work station with photos of her two daughters.
"She was a wonderful mom," Kristin Guadagno told the Milwaukee Journal Sentinel. "She had two daughters who were the foundation of her family. She was their everything. She worked so many hours every week to provide for them and take them on nice trips."
The shootings that happened about 11 a.m. Sunday triggered chaos in the commercial area around the spa. Believing Haughton had fled, police began a massive, six-hour search that locked down a nearby mall, country club and hospital.
Tushaus said later that a fire in the spa, discovery of a propane tank initially believed to be an improvised explosive device and the layout of the building, with many small rooms and locked areas, all slowed officers' search and delayed the discovery of the gunman's body.
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.
Sunday's shooting 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.
