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.

Also killed were Cary Robuck, a 35-year-old nail technician from Racine, and Maelyn Lind, 38, of Oconomowoc.

Zina Haughton wrote in a restraining order request filed Oct. 8 that her husband had threatened to kill her if she ever left him. He also, at various times, threatened to throw acid on her face and burn her and her family with gas.

“His threats terrorize my every waking moment,” Zina Haughton wrote.

She said when she drove to work after picking up items from her home, she found her husband waiting for her in a car outside the spa. He leaned out of the vehicle and, in front of her and two co-workers, slashed her vehicle’s tires. He was later arrested.

Radcliffe Haughton appeared in court Thursday, when a judge issued a four-year restraining order and told him to turn in all firearms to a county sheriff. It’s not clear whether he turned in any weapons.

He bought the .40-caliber semiautomatic handgun used in the shootings on Saturday, Brown Deer police said in a statement.

Hospital spokeswoman Kathy Sieja said one survivor was released from the hospital Monday and the others were in satisfactory condition.
