The latest mass killing in the U.S. happened Wednesday in Winder, Georgia, where four people were fatally shot at Apalachee High School.
Students ran for safety in the football stadium. While officers swarmed the campus near Atlanta, parents raced to find out if their children were safe.
It was the country’s 30th mass killing this year, according to a database maintained by media and USA Today in partnership with Northeastern University.
At least 131 people have died this year in those killings, which are defined as incidents in which four or more people die within a 24-hour period, not including the killer — the same definition used by the FBI.
Last year ended with 217 deaths from 42 mass killings in the U.S., making 2023 one of the deadliest years on record.
