BROOKFIELD, Wisconsin (AP):

A man police suspected of killing three and wounding four by opening fire at a tranquil day spa was found dead yesterday afternoon following a six-hour manhunt that locked down a shopping centre, country club and hospital in suburban Milwaukee.

Authorities said they believed the shooting was related to a domestic dispute. The man they identified as the suspect, Radcliffe Franklin Haughton, 45, of Brown Deer, had a restraining order against him.

Haughton's father, who is also named Radcliffe Haughton, was reported on the website www.menomoneefalls.patch.com as saying his son was born in Jamaica and moved to Milwaukee as an adult.

On his Facebook page, Kingston, Jamaica, is listed as the younger Haughton's hometown.

Brookfield Police Chief Dan Tushaus said Haughton died of a self-inflicted gunshot wound and was found in the spa. Authorities initially believed Haughton had fled and spent much of yesterday looking for him.

The shooting happened about 11 a.m. at the Azana Day Spa, a two-storey, 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.

Online court records showed a temporary restraining order was issued against Haughton on October 8 in Milwaukee County Circuit Court because of a domestic abuse complaint. Haughton appeared in court last Thursday, when a no-contact order was issued, and he was told to turn all his weapons over to the sheriff's department.

It was not clear who sought the restraining order, but his father said he was married.
