The Gun That Killed Trayvon Martin Finds a Buyer

George Zimmerman said Wednesday he has sold the handgun he used to kill Trayvon Martin in 2012.

Though he did not specify how much the 9 mm Kel-Tec PF-9 pistol sold for, bidding for the weapon started at $100,000 when Zimmerman placed the gun up for sale on the United Gun Group website last week. The last offer was made by someone using the name “John Smith,” who bid $138,900 one minute before the auction closed, reports The Orlando Sentinel. The gun had recently been returned to Zimmerman by the U.S. Department of Justice.

In a statement on his website, Zimmerman said:

The process of notifying the winning bidder will begin immediately. The winning bidder will ultimately decide if they want their information to be maintained in confidentiality and they are assured that I will withhold their identity from all media and private parties.

Zimmerman was acquitted of murder charges for killing Martin, an unarmed 17-year-old, in Sanford, Florida. Zimmerman, who was a neighborhood-watch volunteer, said he shot Martin in self-defense. Proceeds of the sale will go to “several worthy causes,” he said, which includes combating the Black Lives Matter movement.
