Police probe motive of gunman who unleashed deadly hail of bullets inside salon before taking his own life.
Investigators and eyewitnesses are revealing more details of Sunday's deadly spa shooting.
Witnesses inside the Azana Salon and Spa in Brookfield, Wisconsin say Radcliffe Haughton's first victim was his estranged wife, Zina Haughton, whose actions before being shot are described as heroic.
Betty Brunner, one of Zina Haughton's customers said that Zina fearlessly intervened when Radcliff Haughton entered and pulled out a gun.
"At that point, Zina jumped, walked in front of the reception area and took on a leadership role," Brunner said, "and just kept trying to talk him through it, trying to prevent him from going after other people."
