George Zimmerman is putting the handgun he used in the 2012 fatal shooting of Trayvon Martin up for auction.
In an interview with a TV station, the former neighbourhood watch volunteer said he had just got the pistol back from the US Justice Department after he was acquitted over the 17-year-old’s death.
He claims he is listing the 9mm Kel-Tec PF-9 pistol, with a starting price of $5,000, so he can “move past the firearm”.
He told WOFL: “And I thought it’s time to move past the firearm. And if I sell it and it sells, I move past it.
“Otherwise, it’s going in a safe for my grandkids and never to be used or seen again.”
The auction is set to being on Thursday.
According to the listing, part of the proceeds from the sale will go towards fighting against violence by the Black Lives Matter movement against law enforcement, combating anti-gun rhetoric by Democratic presidential candidate Hillary Clinton and ending the career of Angela Corey, who led the prosecution against Mr Zimmerman.
When asked what he thought of people opposed to the auction, he said: “They’re not going to be bidding on it, so I couldn’t care less about them.”
Mr Zimmerman said he was defending himself when he shot and killed Trayvon, who was unarmed. He was acquitted of second degree murder and manslaughter charges.
The shooting and acquittal sparked protests across the US and a national debate on race relations.
A lawyer for Trayvon Martin’s family told the TV channel: “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.”
Mr Zimmerman claimed he has been subjected to death threats since the shooting.
He added: “I’m a free American. I can do what I want with my possessions.”
