Police scoured a Fedex facility in Indianapolis and interviewed scores of witnesses Friday in search of a motive for the latest mass shooting to rock the US, as family members of the eight victims spent agonizing hours waiting for word on their loved ones.
One of the people taken to a hospital was in critical condition, Cook said. Two people were treated at the scene and released, and there were reports of several walk-ins at area hospitals.
"We're still working with FedEx security for anything that might have been an indication this was going to happen right now", Indianapolis Metropolitan Police Department Deputy Chief of Criminal Investigations Craig McCartt said at the briefing on Friday.
"There was no confrontation with anyone that was there", Mr McCartt said.
Boillat told the television station that he "didn't exactly see a person get shot but, after hearing the shooting, I did see a body on the floor behind a vehicle". Eight people died, not including the gunman, she said.
Live video showed police tape at the scene of the incident, which follows several mass shootings in recent weeks.
Another witness told WTTV that his niece was sitting in her auto in the driver's seat when the gunfire erupted, and she was wounded.
"She got shot on her left arm", said Parminder Singh.
"It is very heart-breaking and, you know, in the Indianapolis Metro Police Department, the officers responded, . they went in and they did their job", she said.
Dead in Shooting at Indianapolis FedEx Facility
As per data, almost 40,000 people in the United States die each year from the violence induced by guns. The issue of gun regulation in the United States is politically fraught.
Taylor spoke from a hotel where family members are awaiting word on their loved ones.
Some said employees aren't allowed to have their phones with them while working shifts at the facility, making it hard to contact them, WTHR-TV reported.
"This is a tragedy, but we will come through it with flying colours", Cook said through tears during a news conference early Friday. Past year saw a total of 43.549 deaths, and 610 in mass shootings.
Ms Cook confirmed eight people had died plus the gunman, while many others were injured. The shooter also took their own life. 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 an argument at a home in March. Another 10 were killed in gunfire at a supermarket in Boulder, Colorado.
"All of us at Indiana University are appalled and devastated by the tragic and heart-wrenching events of last evening at the FedEx Ground facility in Indianapolis, and we mourn the victims".
His sentiment was echoed by prominent United States federal politicians.
According to one count, the U.S. has had 45 mass shootings - defined as an incident that results in four or more casualties (dead or wounded) over the past month. No country should accept this now-routine horror.
Indianapolis Mayor Joe Hogsett tweeted: "This morning, Indianapolis residents are confronted with the horrific news of yet another mass shooting, an act of violence that senselessly claimed the lives of eight of our neighbors".
