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

There have been at least 627 mass shootings in the U.S. so far this year, according to the Gun Violence Archive.

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

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

At this time last year, the country had experienced 617 mass shootings.

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 Lewiston Maine; Nashville, Tennessee; Buffalo, New York, and Uvalde, Texas, continue to have cities in mourning and have sparked repeated calls for gun reform.

The October mass shooting in Lewiston was the deadliest shooting of the year -- and one of the deadliest in recent decades. It left at least 18 people dead and 13 more injured, according to Maine Gov. Janet Mills.

Here's a look at some of the other mass shooting tragedies the U.S. has seen so far this year:

Three people were killed and five others injured after a shooting at multiple locations on Michigan State University's East Lansing campus on the night of Feb. 13, according to local police. The suspect has died from a self-inflicted gunshot wound, officials said.

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. Police then received a report of another shooting and responded to the MSU Union building, where they found other victims, according to Rozman.

Police are still working to determine the suspect's possible motive, the interim deputy chief said.

The shooting in Oakland was the third mass shooting in California in just three days.

Suspect Huu Can Tran, 72, was found dead of a self-inflicted gunshot wound inside a white cargo van in Torrance that law enforcement officers had surrounded and forced their way into about 30 miles from where the massacre occurred, authorities 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.

Dotson indicated that police are unaware of a motive. He also said law enforcement from Enoch City, Iron County, Cedar City are cooperating in the investigation.

“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.”
