MILWAUKEE (WKOW) -- The gun used in the mass shooting at a Brookfield salon this weekend was bought online from an unregulated private seller.
WISN-TV in Milwaukee reports Radcliffe Haughton was able to buy the gun even though he was barred from having any weapons. The sale was legal, and now the loophole is getting national attention.
Milwaukee Mayor Tom Barrett and New York City Mayor Michael Bloomberg are speaking out against the online marketplace called "ARMSLIST." WISN says private sellers can sell their goods without regulation, no questions asked.
WISN reports ARMSLIST is where Haughton bought the gun used in the mass shooting Sunday at Azana Day Spa. He killed three women, including his estranged wife. Haughton bought the gun just two days after a court commissioner issued a restraining order against him with an order to turn over all weapons.
ARMSLIST doesn't require a background check. Milwaukee Mayor Tom Barrett told WISN, "Had a background check been required on this sale Mr. Haughton may not have been able to obtain the gun he used to murder his wife and her co-workers."
New York Mayor Michael Bloomberg denounced the gun sale Wednesday. He says a sting operation in his city revealed more than half of the sellers they approached on ARMSLIST agreed to sell guns to investigators who posed as buyers and had claimed they couldn't pass a background check.
Police say it's hard to keep track of private sales. Brown Deer Police Chief Steven Rinzel told WISN, "Do I think it's a good idea to have a waiting period for handgun sales? Yes. How in the world would you ever do that in reality? If (someone) wants to sell me a weapon, how do we have a three day waiting period? How do we do that?"
Mayor Barrett says all sales need to go through a third party for a background check.
