Update: The original website being used to auction the gun George Zimmerman used to kill unarmed 17-year-old Trayvon Martin—Gunbroker.com—removed the listing from its site.

“We want no part in the listing on our web site or in any of the publicity it is receiving,” the company said in a statement.

But Zimmerman is now hosting the auction on a different gun site called UnitedGunGroup.com, according to The Washington Post.

“I talked to George Zimmerman earlier today and told him that as long as all laws are being followed, he can list the gun on our site,” Todd Underwood, the owner of the site, said to The Post. “I don’t support it, I don’t condone it, I don’t have anything against it. It’s his property, it’s his decision.”

Original: Just in case you thought murderer and domestic abuser George Zimmerman had already gone as low as he could, he’s here to remind you that he can come up with even more ways to make your stomach turn.

Zimmerman is trying to sell the gun he used to kill 17-year-old Trayvon Martin in 2012. He posted the 9 mm pistol for auction on GunBroker.com. Bids start at $5,000 when the auction goes live at 11 a.m. this morning.

“I am honored and humbled to announce the sale of an American Firearm Icon. The firearm for sale is the firearm that was used to defend my life and end the brutal attack from Trayvon Martin,” he writes. “Many have expressed interest in owning and displaying the firearm including The Smithsonian Museum in Washington D.C. This is a piece of American History.”

There’s more than one lie in there, but the Smithsonian has called out one of them.

We have never expressed interest in collecting George Zimmerman’s firearm, and have no plans to ever collect or display it in any museums

Fox 35 Orlando contacted the Martin family’s attorney, who responded with a statement that reads, “The Trayvon Martin Foundation is committed to its mission of ending senseless gun violence in the United States. This election season, we are laser focused on furthering that mission. As such, the foundation has no comment on the actions of that person.”
