A list of mass killings in the United States this year

The latest mass killing in the US occurred on Sunday in King City in central California, where police said a group of men wearing masks opened fire at an outdoor party, killing four people and wounding seven others.

Police said they responded to a reported shooting and found three men with gunshot wounds who were pronounced dead in a front yard. A woman also died after someone took her to an area hospital about 105 miles (170 kilometers) south of San Jose.

Several people were at the party outside a house when three men wearing dark masks and clothing got out of a silver car and shot at the group. The suspects then fled in the car. The investigation is still ongoing, police said.

King City is a community of about 14,000 people in the southern farm country of the Salinas Valley, on the inland side of the coastal mountains. The US Army Fort Hunter Liggett Training Center is nearby. The city is also known as the gateway to Pinnacles National Park.

This was the 10th mass killing in the country this year, according to a database maintained by The Associated Press and USA Today in partnership with Northeastern University.

At least 47 people have been killed this year in these killings, which are defined as incidents in which four or more people are killed within a 24-hour period, not including the killer — the same definition used by the FBI.

The country is currently witnessing the third highest number of deaths from mass killings in a single year. Only 2023 and 2008 saw more, with 57 deaths each. Last year ended with 42 mass murders and 217 deaths, making it one of the deadliest years on record.

According to the database, 584 mass killings have occurred since Monday, killing 3,036 people and injuring 2,047.
