"Radcliffe Haughton had threatened violence against his wife before. Last year, he barricaded himself..."

Radcliffe Haughton had threatened violence against his wife before. Last year, he barricaded himself in the couple’s home, where police said he pointed a “long-barreled black object” out the window at Zina Haughton after she called for emergency help, according to court records.

This month, Zina called police to report that her husband had slashed her car’s tires outside her workplace.

“His threats terrorize my every moment,” she wrote in a petition requesting a temporary restraining order.

Despite the threats, Radcliffe Haughton was never convicted of serious offenses. But Sunday, authorities said Haughton made good on his threats, killing his 42-year-old wife and two other women and wounding four others in a shooting spree at the Azana Salon & Spa in Brookfield, Wis., west of Milwaukee. Haughton then turned the gun on himself inside the salon, where his body was found later.
