Mass shootings and violence leave dead and injured across the US this weekend

Mass shootings and violence killed and wounded people across the United States this weekend, including four people found dead of gunshots in a small Idaho town, a Pennsylvania state trooper killed in an ambush, multiple people firing guns into an Illinois holiday crowd and bullets flying among teenagers partying in Missouri.

The shootings happened in cities and rural areas alike, following a surge in homicides and other violence over the past several years that accelerated during the coronavirus pandemic. This weekend also brought mass shootings in Washington state, Philadelphia, San Francisco, Southern California and Baltimore.

“There’s no question there’s been a spike in violence,” said Daniel Nagin, a professor of public policy and statistics at Carnegie Mellon University. “Some of these cases seem to be just disputes, often among adolescents, and those disputes are played out with firearms, not with fists.”

Researchers disagree over the cause of the increase. Theories include the possibility that violence is driven by the prevalence of guns in America, or by less aggressive police tactics or a decline in prosecutions for misdemeanor weapon offenses, Nagin said.

Only the Idaho killings fit the definition of a mass killing in which four or more people die, not including the shooter. However, the number of injured in most of the weekend cases matches the widely accepted definition for mass shootings.

Here’s a look at the shootings this weekend:

Kellogg, Idaho

Police in Idaho arrested a suspect in a shooting that killed four people on Sunday at a home behind a church.

Responding officers found four people, all dead from gunshot wounds, at a residence in Kellogg, according to the Shoshone County Sheriff’s Office and news reports. Idaho State Police said a 31-year-old man was detained, KXLY-TV reported.

A neighbor at the scene told the TV station that there had been an ongoing dispute between neighbors at the location. It happened behind the Mountain View Congregational Church, the Shoshone News-Press reported.

Willowbrook, Illinois

At least 23 people were shot, one fatally, early Sunday in a suburban Chicago parking lot where hundreds of people had gathered to celebrate Juneteenth, authorities said.

The DuPage County sheriff’s office described a “peaceful gathering” that suddenly turned violent as a number of people fired multiple shots into the crowd in Willowbrook, Illinois, about 20 miles (32 kilometers) southwest of Chicago.

A motive wasn’t immediately known. Sheriff’s spokesman Robert Carroll said authorities were interviewing “persons of interest,” the Daily Herald reported.

“We just started hearing shooting, so we dropped down until they stopped,” a witness, Markeshia Avery, told WLS-TV.

The White House issued a statement calling the violence a tragedy and saying the president was thinking of those killed and injured. Illinois Gov. JB Pritzker said in a statement that he was monitoring the investigation.

“Gathering for a holiday gathering should be a joyful occasion, not a time where gunfire erupts and families are forced to run for safety,” Pritzker said.

Washington State

Two people were killed and two others were injured when a shooter began firing “randomly” into a crowd at a Washington state campground where many people were staying to attend a nearby music festival on Saturday night, police said.

The suspect was shot in a confrontation with law enforcement officers and taken into custody, several hundred yards from the Beyond Wonderland electronic dance music festival.

A public alert advised people of an active shooter in the area and advised them to “run, hide or fight.”

The festival carried on until early Sunday morning, Grant County Sheriff’s Office spokesman Kyle Foreman said. Organizers then posted a tweet saying Sunday’s concert was canceled.

Central Pennsylvania

One state trooper was killed and a second critically wounded just hours apart in central Pennsylvania on Saturday after a gunman attacked a state police barracks.

The suspect drove his truck into the parking lot of the Lewistown barracks about 11 a.m. Saturday and opened fire with a large-caliber rifle on marked patrol cars before fleeing, authorities said Sunday.

Lt. James Wagner, 45, was critically wounded when he was shot after encountering the suspect several miles away in Mifflintown. Later, Trooper Jacques Rougeau Jr., 29, was ambushed and killed by a gunshot through the windshield of his patrol car as he drove down a road in nearby Walker Township, authorities said.

The suspect was shot and killed after a fierce gunbattle, said Lt. Col. George Bivens, who went up in a helicopter to coordinate the search for the 38-year-old suspect.

“What I witnessed ... was one of the most intense, unbelievable gunfights I have ever witnessed,” Bivens said, lauding troopers for launching an aggressive search despite facing a weapon that “would defeat any of the body armor that they had available to them.”

A motive was not immediately known.

St. Louis

An early Sunday shooting in a downtown St. Louis office building killed a 17-year-old and wounded 10 other teenagers, the city’s police commissioner said.

St. Louis Metropolitan Police Commissioner Robert Tracy identified the victim who was killed as 17-year-old Makao Moore. A spokesman said a minor who had a handgun was in police custody as a person of interest.

Teenagers were having a party in an office space when the shooting broke out around 1 a.m. Sunday.

The victims ranged from 15 to 19 years old and had injuries including multiple gunshot wounds. A 17-year-old girl was trampled as she fled, seriously injuring her spine, Tracy said.

Shell casings from AR-style rifles and other firearms were scattered on the ground.

Southern California

A shooting at a pool party at a Southern California home left eight people wounded, authorities said Saturday.

Authorities were dispatched shortly after midnight in Carson, California, south of Los Angeles, KABC-TV reported.

The victims range in age from 16 to 24, the Los Angeles County Sheriff’s Department said in a statement. They were taken to hospitals and two were listed in critical condition, the statement said.

Authorities said they found another 16-year-old boy with a gunshot wound when they responded to a call about a vehicle that crashed into a wall nearby.

Baltimore

Six people were injured in a Friday night shooting in Baltimore. All were expected to survive.

Officers heard gunshots in the north of the city just before 9 p.m. and found three men with numerous gunshot wounds. Medics took them to area hospitals for treatment.

Police later learned of three additional victims who walked into area hospitals with non-life-threatening gunshot wounds.

The wounded ranged in age from 17 to 26, Baltimore Police Department spokesperson Lindsey Eldridge said.

San Francisco

Six people were injured after a “car-to-car” shooting in the streets of San Francisco on Sunday evening, police said.

Two victims sustained gunshot wounds, one with life-threatening injuries, in the moving shootout beginning shortly before 7 p.m., San Francisco Police Chief Bill Scott said at a news conference Sunday.

Suspects in two cars, a black SUV and a white sedan, “drove very recklessly and chased each other while engaged in gunfire” near the northern waterfront, Scott said. The area includes Fisherman’s Wharf, one of the city’s busiest tourist areas.

Three victims were injured by glass shards caused by “errant gunfire,” Scott said, with none of the injuries considered to be life-threatening.

Two girls, ages 10 and 16, were struck by one of the two vehicles while walking their bicycles across the street. The younger girl was injured and transported to a hospital with non-life-threatening injuries while the older girl was not injured, Scott said.

“It appears that this was an isolated incident and these individuals were targeting each other. We don’t believe this was random at all,” he said.

Philadelphia

A 4-year-old boy was among five victims of a shooting in south Philadelphia Saturday night.

Police responded to the block shortly before 8 p.m. Saturday and found a 58-year-old woman with gunshot wounds to the legs, a 54-year-old woman with gunshot wounds to her wrist and leg, and the boy, who was brought to Presbyterian Hospital with a gunshot wound to the abdomen.

A 30-year-old man also arrived at the hospital with a gunshot wound to the wrist and a 40-year-old man was brought in with a gunshot wound to the abdomen. The last victim was listed in critical condition; all others were said to be in stable condition.

Police said the shooter was an unidentified person wearing dark clothing.
