At this writing, at least fifty people are reportedly dead and hundreds more were wounded after a mass shooting attack by Stephen Paddock during a Jason Aldean appearance outside the Mandalay Bay resort in Las Vegas on Sunday night, October 1. These numbers make it the deadliest event of its kind in U.S. history, but hardly an isolated one. In the five-plus years since July 20, 2012, when twelve people were killed and seventy were injured during James Holmes's attack at the Century 16 theater in Aurora, 1,864 incidents like it have taken place, according to online estimates.

Over the years, we've attempted to catalogue the carnage nationwide in relation to shootings and slayings in Colorado. On April 20, 2009, the tenth anniversary of the attack on Columbine High School, we published "The Columbine Effect: A Horrific Roster of School Shootings Since 1999," which used data from The Brady Campaign to Prevent Gun Violence to detail 108 school shootings over the span of that decade. A 2012 update, shared after the December 2012 killings in Newtown, Connecticut, added 73 more. Then, in October 2015, following an assault on the Umpqua Community College in Roseburg, Oregon, we crunched the numbers again and documented another 81 school shootings, bringing the total to 262.

In December 2015, after shocking gun violence at a Planned Parenthood branch in Colorado Springs killed three and wounded nine, we broadened the focus of a subsequent post to mass shootings in general during that calendar year. The sum is mentioned in our headline: "351 Mass Shootings From Jan. 1 to Planned Parenthood Attack."

Calculating the mass shootings from July 2012 to yesterday is difficult simply because there have been so many of them, and definitions vary. But assorted organizations have tried their best. In the wake of Newtown, for example, the aforementioned Brady Campaign issued a document titled "Mass Shootings in the United States Since 2005" that listed fourteen such incidents after the Aurora theater slayings in 2012 in which at least three people were wounded or killed. Here's that list, in reverse chronological order:

The following year, 2013, National Rifle Association president David Keene said, "Today, guns are cool" — a controversial phrase that lives on in Guns Are Cool, a Reddit site that uses crowd-sourcing techniques to track mass shootings, defined by the site as an event in which four people are wounded or killed. The data collected by the site can't be considered definitive, but it's arguably the best available.

The results are dispiriting and maddening. Guns Are Cool pages for the past five years show 339 shootings in 2013, 325 in 2014, 371 in 2015, 477 in 2016 and 338 in 2017 prior to last night's massacre. And there are still almost three months of 2017 left.

By our calculations, that brings the total right now to 1,864. And while we'd love to say the deaths will end there, such optimism is impossible given what's happening at present in Las Vegas.
