At least eight children were found fatally shot early Sunday in a home in Shreveport, La., after police investigated what they said was a domestic violence call, according to authorities.

The incident happened around 6 a.m. local time in the Cedar Grove neighborhood of South Shreveport, according to Shreveport Police Cpl. Chris Bordelon, who said the suspect was shot and killed after a police chase.

Several other people were also injured in the incident, police said.

Bordelon said police are investigating a “very large scene with four specific locations” and that officers responded to a home in the south Shreveport neighborhood on a report of gunfire.

“In doing so, we’ve determined that this was a domestic call in nature,” Bordelon said.

He further said that the crime scene spanned two residences next door to each other and a third home nearby.

House Speaker Mike Johnson, R-La., in whose district the shooting occurred, said his team is “in touch” with local law enforcement and offered his “thoughts and prayers” for the victims and their families.

“Heartbreaking tragedy in Shreveport this morning – 8 children were senselessly killed and multiple others were injured,” Johnson said in a social media post. “We’re holding the victims, their families and loved ones, and our Shreveport community close in our thoughts and prayers during this incredibly difficult time.”

Bordelon said the ages of the children who were killed ranged from an 18-month-old infant to a 14-year-old.

Two other shooting victims, both adults, were found and police suspect they were attacked by the same suspect who killed the children, Bordelon said.

“We do know that some of the children inside were his descendants,” Bordelon said.

Bordelon further said that after allegedly committing the killings, the suspect, whose name was not immediately released, carjacked a vehicle in the area.

“Shreveport patrol officers got behind that vehicle and they chased it into Bossier Parish, at which point in time Shreveport officers did discharge their firearms and that individual is deceased,” Bordelon said.

Shreveport Tom Arceneaux described the deadly incident as “maybe the worst tragic situation we’ve ever had in Shreveport.”

Shreveport Police Chief Wayne Smith said his department is using all the resources it can to investigate the incident to determine “exactly what took place.”

“I just don’t know what to say,” Smith said. “My heart is just taken aback. I just cannot begin to imagine how such an event can occur.”
