Police identified the suspect as Radcliffe Franklin Haughton, 45, of Brown Deer, Wisconsin. Brookfield Police Chief Dan Tushaus said Haughton's car had been found, but he was still at large. The shooting happened about 11 a.m. at the Azana Day Spa, a two-story, 9,000-square-foot (836-square-meter) building across from a major shopping mall in a middle- to upper-class community west of Milwaukee, AP reported. An improvised explosive device was found at the spa, and a bomb squad was investigating, Tushaus said.
