MIAMI (AP): Bidding in an online auction for the pistol former neighborhood watch volunteer George Zimmerman used to kill Trayvon Martin had gone well into the millions of dollars by Friday morning, though it was unclear if they were serious bids.

The website for United Gun Group began hosting the auction Thursday after another website, GunBroker.com, took down the auction.

Hours later, United Gun Group tweeted that it would post Zimmerman’s ad. The new link was posted, along with a statement from Zimmerman. The site calls itself a “social market place for the firearms community.”

Bidding on the 9 mm Kel-Tec PF-9 pistol began at $5,000. By Friday morning, the site showed bidding had surpassed $36 million with the leading bidder using the screen name “Racist McShootface.”
