The 150 or so revelers had gathered to blow off steam before the holidays. Then an argument triggered a hail of bullets that sent them sprinting for the exits.

This wasn’t San Bernardino, California, on December 2. It was Calumet City, a suburb of Chicago, Illinois, in December 2014. When the gunfire ceased, 10 people were wounded, including Dewayne Purnell, who lay on the floor with two bullet holes in his back. Emergency workers tried in vain to save him. The 19-year-old was dead within an hour.

Purnell was set to leave for Fort Jackson in South Carolina to join the Army in nine days — “to see the world,” his mother said. Purnell’s father added that his imminent departure was the only reason he was allowed to attend the party, which was just a half-mile from home. “I let him go out one night, and I’m never going to see him again.”

The Calumet City incident falls into a category of mass shootings that barely generates headlines. There is no official definition for a “mass shooting,” but one popular metric uses the Federal Bureau of Investigation’s criteria for a mass murder and applies it to gun violence, setting the threshold at four or more killed while also excluding gang-related violence. Another, promoted by a project called the Mass Shooting Tracker, defines a mass shooting as four or more people shot in a single event.

It’s understandable that crimes with higher body counts generate greater interest — to a degree, sadness and drama multiply along with the number of lives lost. But America’s fixation on the deadliest of mass shootings has the effect of warping perceptions of the true pervasiveness of gun violence. Mass shootings account for less than 1.5 percent of the country’s 33,600 annual gun deaths. And fatalities, in turn, are only one aspect of gun violence. To capture its full extent means including the 84,000 people wounded annually by gunfire, many of whom are sidelined by injuries that persist for the rest of their lives. It means include shootings that generate neither wall-to-wall coverage nor tweets of “thoughts and prayers” not primetime addresses from the president.

Going back 365 days, from December 2, 2014 to December 2, 2015, The Trace found 13 incidents with casualty numbers at least double the four needed to qualify as a mass shooting under the Mass Shooting Tracker’s definition. In all, sixteen people were killed and 136 people wounded in these forgotten outbreaks of gun violence.
