Mass killings have claimed four or more American lives every week for the past six weeks, leaving 48 dead and eight wounded in their wake.
The USA TODAY/AP/Northeastern University mass killings database has tracked a dozen mass killings in 2021 that have left 68 people dead and 15 people injured. Three of those events happened in just one week.
Thursday night's shooting at a FedEx facility in Indianapolis was the second deadliest of the year. A gunman fired at random both inside and outside the facility, killing eight and wounding four others, according to Indianapolis Deputy Police Chief Craig McCartt.
Here's a look at the details of the eight mass killings in the past six weeks:
COVID-19 stimulus check
Indianapolis Police said a dispute over a COVID-19 relief check appears to have escalated into gunfire. The shooting left four people dead, including a child. The suspect allegedly wanted at least $700 from the relief check, but a woman who was wounded in the shooting refused to share that much.
Atlanta-area spa shootings
A 21-year-old Georgia man was arrested in the killings of eight people – including six women of Asian descent – at three Atlanta-area spas. According to authorities, the suspected gunman had previously visited two of the spas. He claimed he was a sex addict and was trying to eliminate temptation.
