The man who shot and killed black teenager Trayvon Martin in the USA has listed the gun he used on an auction site with plans for some of the proceeds to go fight the Black Lives Matter movement.
On Thursday the gun had been listed on GunBroker.com by George Zimmerman. He used the gun to kill 17-year-old Trayvon Martin in Florida four years ago.
However, on Thursday evening GMT, the gun had been removed from the site around the time the bidding was due to begin. Then, hours later it was relisted on a different gun auction website, unitedgungroup.com.
The listing had said people could bid on a “piece of history."
Zimmerman, then a neighborhood watch volunteer, shot and killed the unarmed teenager in February 2012, in a confrontation as Trayvon was heading back to a relative's house in Sanford, Florida after buying skittles at a convenience store.
A jury found Zimmerman, who alleged that Martin was trying to bash his head on the pavement during a struggle, not guilty of second-degree murder and manslaughter.
The killing and the verdict set off global civil rights protests, called the Black Lives Matter movement.
In the gun listing, for the Kel-Tec PF-9 9mm firearm Zimmerman wrote he was "honored and humbled" to announce the sale of the weapon and set the bidding to start at $5,000.
"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," he wrote.
"This is a piece of American History," he wrote.
Tracy Martin, Trayvon's father, issued a statement Thursday through his lawyer, Benjamin Crump, saying a foundation in his son's name is focusing on ending senseless gun violence and "has no comment on the actions of that person that murdered Trayvon."
Zimmerman claimed in his auction listing that the "Smithsonian Museum" in Washington, D.C., had expressed interest in buying the firearm, however, the Smithsonian Institution said Thursday on Twitter, "We have never expressed interest in collecting George Zimmerman’s firearm, and have no plans to ever collect or display it in any museums."
He said he planned to use the proceeds from the sale of the gun to fight "Black Lives Matter" violence against law enforcement officers and to counter "Hillary Clinton's anti-firearm rhetoric."
He also said money would be used to "ensure the demise of Angela Correy's (sic) persecution career." Corey was the special prosecutor appointed to investigate Martin's death, US Today reports.
"George Zimmerman" quickly became the top trending term on Twitter in the United States, with many users on the social media site expressing outrage over the auction.
On the listing on the second website, one commenter said it was "truly disgusting".
Another said "Good, one less gun to defend yourself with Zimmerman. We do not forgive, we do not forget, expect us."
After an hour of the auction being live, there were no bids.
