Background checks jumped more than 41 percent since Friday's shooting that left 12 dead and 58 injured during a midnight screening of "The Dark Knight Rises" at an Aurora movie theater. Over the weekend, the Colorado Bureau of Investigation approved background checks for 2,887 people who wanted to purchase a firearm, the Post said, an increase of 43 percent over the previous weekend.
"It's been insane," Jake Meyers, an employee at Rocky Mountain Guns and Ammo in Parker, Colo., told the paper.
Spikes in gun sales are not uncommon in the aftermath of mass shootings like the one in Colorado. Following the January 2011 shooting that killed six and wounded more than a dozen others—including former Arizona Rep. Gabrielle Giffords—in Tucson, sales of handguns soared more than 60 percent in the state, according to FBI data. Similar spikes were seen after the massacres at Virginia Tech and Columbine.
