BROOKFIELD, Wisconsin - 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.

Unconfirmed reports are that the man identified as Radcliffe Franklin Haughton was from Jamaica.

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 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 11:00 am.

They initially believed an improvised explosive device was inside the building, but later said that was not the case.

The shooting happened at the Azana Day Spa, a two-story, 9,000-square-foot building across from a major shopping mall in Brookfield, a middle-to-upper class community west of Milwaukee. Hours later, a bomb squad descended on the building, and Tushaus said an improvised explosive device had been found inside. It was not clear whether it remained a threat.
