(CBS News) -- Police in suburban Milwaukee, Wis. say a gunman who opened fire inside a spa Sunday killed three women and wounded four others, and then turned the gun on himself, and his wife may one of the victims.
It was about 11 a.m. when a gunman entered the Azana Salon & Spa in Brookfield, Wis., and opened fire. Audio tapes recorded by police dispatchers captured the chaos that began to unfold.
An officer said at the time, "There are two witness who saw him actively shooting other people. ... She did say that at least one person was shot, she thought possibly in the head, and there was a lot of bleeding."
Police believe the alleged gunman, 45-year-old Radcliffe Haughton, targeted the salon where his estranged wife, Zina Haughton, is an employee.
According to witnesses, Haughton opened fire, shooting people at random and sending customers fleeing in panic.
One witness, Jenny Remshak, said, "Like maybe 10 people came running out of the back of the salon with their hands up, running and screaming out the door."
John Gosh was stopped at a red light nearby when a woman ran into traffic screaming, trying to get his attention. Then the shooter emerged in pursuit, before going back inside the building.
Gosh said, "He looked like a deer in the headlights. He didn't know what was up. She didn't say anything about targeting any one person, he just started shooting people."
When officers finally got inside, three women were found dead and another four were seriously injured. For much of the afternoon, police had the area on lockdown and initially believed that the suspect was still at large, but later said it appeared he had taken his own life.
Brookfield Police Chief Dan Tushaus said, "The one suspect we believe is responsible for the shootings today, is deceased, we believe it to be (a) self-inflicted gunshot wound."
Two weeks ago, Zina Haughton had taken out a restraining order against her husband after reporting that her car tires had been slashed while she was at work.
Police have yet to release the names of those who died, and it is not yet known if she was among the victims.
