A list of mass killings in the United States since January

The latest mass killing in the United States happened Sunday in Kellogg, Idaho

The latest mass killing in the United States happened Sunday in Kellogg, Idaho, where a 31-year-old man was detained at the scene of a shooting that left four people dead inside a residence. The mass shooting was part of a spate of gun violence over the weekend that killed and wounded people across the U.S., including at least 60 shot in the Chicago area alone.

The Idaho shooting is the country’s 27th mass killing of 2023 in which four or more people died, not including the assailant, within a 24-hour period, according to a database maintained by The Associated Press and USA Today in partnership with Northeastern University.

So far this year, the nation has witnessed the highest number on record of mass killings and deaths to this point in a single year. There have been more than 550 mass killing incidents since 2006, according to the database, in which at least 2,900 people have died and at least 2,000 people have been injured.
