Breaking News: Another mass shooting in America: 9 people dead including shooter who committed suicide at FedEx in Indianapolis

Eight people were shot and killed in a late-night shooting at a FedEx facility in Indianapolis, and the shooter killed himself, police said.

Several other people were injured Thursday night when gunfire erupted at the facility near the Indianapolis International Airport, police spokesperson Genae Cook said.

At least four were hospitalized, including one person with critical injuries. Another two people were treated and released at the scene, she said.

A witness told WTHR-TV that he was working inside the building when he heard gunshots.

“I see a man come out with a rifle in his hand and he starts firing and he starts yellin’ stuff that I could not understand,” Levi Miller said. “What I ended up doing was ducking down to make sure he did not see me because I thought he would see me and he would shoot me.”

The shooter wasn’t immediately identified, and investigators were in the process of conducting interviews and gathering information. Cook said it was too early to tell whether the shooter was an employee at the facility.

“We’re still trying to ascertain the exact reason and cause for this incident,” she said.

It was the latest in a recent string of mass shootings across the U.S. Last month, eight people were fatally shot at massage businesses across the Atlanta area, and 10 died in gunfire at a supermarket in Boulder, Colorado.

It was at least the third mass shooting this year in Indianapolis alone. Five people, including a pregnant woman, were shot and killed in January, and a man was accused of killing three adults and a child before abducting his daughter during at argument at a home in March.

“I am heartbroken by the mass shooting at the FedEx facility here in Indianapolis and praying for all affected by this tragedy,” Rep. Andre Carson, a Democrat whose district includes much of the city, tweeted.

Police were called to reports of gunfire Thursday just after 11 p.m., and officers “came in contact with (an) active shooter incident,” Cook said. The gunman later killed himself.

“The officers responded, they came in and did their job. A lot of them are trying to face this, because this is a sight that no one should have to see,” Cook said.

FedEx released a statement saying it is cooperating with authorities and working to get more information.

“We are aware of the tragic shooting at our FedEx Ground facility near the Indianapolis airport. Safety is our top priority, and our thoughts are with all those who are affected,” the statement said.

Family members gathered at a nearby hotel to await word on loved ones. Some said employees aren’t allowed to have their phones with them while working shifts at the facility, making it difficult to contact them, WTHR-TV reported.

Ashlee Floyd told the Indianapolis Star that her father has worked at the facility for two decades. She said he usually calls his wife around 11:25 p.m. but he didn’t call Thursday, so family tried to contact him but he didn’t respond.

“I don’t know if he’s OK. I don’t know if he’s injured. I don’t know if he’s gone. I’m just scared right now,” she said.

Live video from news outlets at the scene showed crime scene tape in the parking lot outside the facility.

Jeremiah Miller, a witness who said he works at the facility, told WISH-TV that he saw a man with some kind of rifle after hearing several gunshots.

Another man told WTTV that his niece was sitting in the driver’s seat of her car when the gunfire erupted, and she was wounded.

“She got shot on her left arm,” said Parminder Singh. “She’s fine, she’s in the hospital now.”

He said his niece did not know the shooter.
