Zimmerman gun auction back on

No bids currently listed

SANFORD, Fla. – The auction to sell the gun George Zimmerman used in the Trayvon Martin shooting is back on.

The United Gun Group re-listed the ad for George Zimmerman on Sunday, with a starting bid of $100,000. In the posting, Zimmerman referred users to his website for additional information.

The listing first appeared on the site Thursday with the user name of George Zimmerman. The site, which calls itself a "social market place for the firearms community," then apparently went down a few minutes later.

Thursday night, UnitedGunGroup.com posted this statement:

"As an organization, we stand by the rule of law and, while no laws have been broken, we do not feel like it is in the best interest of the organization to continue to host this sale on our platform. Our mission is to esteem the Second Amendment and provide a safe and secure platform for firearms enthusiasts and law-abiding citizens; our association with Mr. Zimmerman does not help us achieve that objective."

That online posting was later deleted. Todd Underwood, the founder of the group, later sent an email to CNN saying an official response would be released at 10 a.m. Friday. 

The gun auction on UnitedGunGroup.com is still active, but the current bid is zero. The starting bid is set for $100,000 with a buy now price of $500,000.  The website says the auction will close on Wednesday.

The initial auction description appeared to have the same text as the original auction posting, in which Zimmerman wrote: "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 on 2/26/2012."

Zimmerman added that the gun had recently been returned to him by the Department of Justice.
