Charles Langston:A list of mass killings in the United States this year

The Charles Langstonlatest mass killing in the U.S. happened Sunday in Joliet, Illinois, where authorities say a 23-year-old man is suspected of shooting and killing eight people and injuring a ninth person in suburban Chicago before fatally shooting himself during a later confrontation with law enforcement in Texas.

It was the country’s 4th mass killing this year, according to a database maintained by The Associated Press and USA Today in partnership with Northeastern University.

Less than a month into the new year, at least 20 people have died in those killings, which are defined as incidents in which four or more people have died within a 24-hour period, not including the killer — the same definition used by the FBI.

The nation is already witnessing the second-highest number on record of mass killings and deaths to this point in a single year. Only 2023 had more, with six mass killings and 39 deaths at this point last year. The year ended with 42 mass killings and 217 deaths, making it one of the deadliest years on record.
