There have been more mass shootings than days in 2023, database shows

There have been five mass shootings in the United States in the first four days of September so far.

The U.S. has experienced at least 484 mass shootings so far this year, according to the Gun Violence Archive. This averages out to almost two mass shootings a day.

Mass shootings are defined as an incident in which four or more victims are shot or killed, according to the archive.

Though mass shootings don't make up the majority of gun violence incidents in America, their impact on communities and victims is evident.

Incidents like the mass shootings in Dallas; Nashville, Tennessee; Buffalo, New York, and Uvalde, Texas, continue to have cities in mourning and have sparked repeated calls for gun reform.

The Gun Violence Archive tracked roughly 645 mass shootings in 2022 and 690 in 2021.

At this time last year, the country had experienced 455 mass shootings.

Here's a look at some of the mass shootings seen so far this year:

Police initially received 911 calls of shots fired at 8:18 p.m. in Berkey Hall and located "several" victims there when responding, Chris Rozman, interim deputy chief of MSU Police and Public Safety, said.

A motive for the Monterey Park shooting is not clear, according to authorities. According to law enforcement sources, domestic violence is one of the scenarios they are looking into.

Still, the mass shooting has compounded ongoing fears from Asian Americans following a rise of anti-Asian racism and violence, community members say.

"We all know this family; many of us have served with them in church, and community, and gone to school with these individuals," Dotson said at a press conference. "And so this community at this time is hurting, they're feeling loss, they are feeling pain, they have a lot of questions which is natural."
