Internet trolls on Friday hijacked the auction of the gun George Zimmerman used to kill Trayvon Martin.

One bid on the website of the auctioneer, United Gun Group, for the 9 mm Kel-Tc PF-9 pistol was from a user named “Racist McShootface,” who at one point offered $58 million. Another bidder used the username Tamir Rice, the name of a 12-year-old black boy shot dead by police in Cleveland in 2014 while holding a toy gun.
