MILWAUKEE – A Wisconsin man terrorized his wife for years, threatening to throw acid on her face, dousing her car with tomato juice and slashing her vehicle’s tires before finally going to the spa where she worked, opening fire and killing her and two others.

The shooting spree stunned the middle- to upper-class Milwaukee suburb where it happened, but court records show the conflict between Radcliffe Haughton and his wife had been escalating for years.

The 45-year-old former car salesman ultimately shot seven women at the spa before turning the gun on himself. Three remained hospitalized Monday.
