Authorities say the man accused of killing three and wounding four at a Wisconsin day spa had slashed his wife's tires two weeks before Sunday's shooting.
Brookfield Police Chief Dan Tushaus said at a news conference Sunday night that the man's wife was an employee at the spa. It is not clear if she was among the victims.
The suspect, Radcliffe Franklin Haughton, was found dead inside the spa of a self-inflicted gunshot wound. Authorities said he had a four-year restraining order against him.
Officials described finding smoke inside the spa when they responded to reports of the shooting around 11 a.m.
They initially believed an improvised explosive device was inside the building, but later said that was not the case.
President Barack Obama has called officials in Wisconsin to express condolences for the victims of Sunday's shootings at a day spa in suburban Milwaukee.
The White House says Obama assured Wisconsin Gov. Scott Walker and Brookfield, Wis., Mayor Steven Ponto that the federal government would provide "whatever resources are necessary" to help with the investigation.
The White House says Obama told the officials that the people of Wisconsin were in the thoughts and prayers of himself and first lady Michelle Obama.
