Suspected gunman Radcliffe F. Haughton, 45, was found dead of a self-inflicted gunshot wound at the scene after a mass-shooting spree at the Azana Salon & Spa in Brookfield, Wis., that killed three females and wounded four other people on Sunday, according to local police.

Haughton, who resided in Brown Deer, Wis., was described as an African-American standing 6 feet 2 inches tall and weighing about 270 pounds by the Milwaukee Journal Sentinel's JSOnline.

Early reports about the suspect being seen fleeing the scene of the crime wearing a gray sweater and blue jeans while carrying a black-and-white backpack were apparently erroneous.

Haughton is suspected of opening fire at the salon across the street from the Brookfield Square Mall around 11 a.m. local time (noon EDT). He apparently attempted to take the salon’s receptionist hostage after shooting her in the leg, but the woman was able to escape and is currently in stable condition in a nearby hospital, JSOnline said.

As of 4:30 p.m. EDT, police had still not completely checked out the salon because they found what appears to be an improvised explosive device in the building. The Milwaukee bomb squad is reportedly on the scene.

JSOnline spoke by phone with Haughton’s father, Radcliffe F. Haughton Sr., at his home in Florida after the mass shooting and before the news broke about his son's fate. The father may have shed some light on a possible motive behind his son's apparent rampage.

"So he hasn't been apprehended? Oh Lord. Have mercy, God," the father said when he first heard about his son’s alleged crimes.

Last Thursday, the Milwaukee County Circuit Court issued a restraining order against the younger Haughton and for his wife, Zina Haughton, who may be an employee of the Azana Salon & Spa.

As a result, the son asked the father by phone last week whether he could stay with him in Florida, saying he did not believe he could live in Wisconsin at the time.

"He told me, 'I have to get out of Wisconsin.' I told him, 'Whatever you do, don't do anything stupid,'" the suspect's father said. "I am so saddened. I don't know what to tell you. As his father, I am very, very sorry, and I did not expect this from my son."
