Crime scene investigators walk through the parking lot of the mass shooting site at a FedEx facility in Indianapolis, Indiana, on April 16, 2021.

A gunman opened fire at a FedEx facility in Indianapolis, Indiana, Thursday evening, killing at least eight individuals.

All eight who were killed were employees of the company. Multiple other individuals were also reportedly injured in the shooting and taken to hospitals in the area. The gunman reportedly died of a self-inflicted gunshot wound, authorities said.

The shooting happened around 11 pm Thursday evening. The shooter’s motives and connection to the facility were not immediately clear. “With less than 12 hours since the shooting, it would be premature to speculate” on what the shooter’s motive was at this time, said Paul Keenan, special agent in charge of the FBI Indianapolis Field Office.

One witness described the shooter as using an automatic weapon of some kind. It’s believed that the individual was acting alone.

Attorney General Merrick Garland has been briefed on the situation, a source in the Justice Department told ABC News. President Joe Biden was also briefed on the matter on Friday morning.

For some time, loved ones of the FedEx workers were unable to find out whether their friends or family members were victims of the shooting, The Indianapolis Star reported, because of a FedEx policy prohibiting employees from carrying cellphones with them at work.

“It is hard because if my friend had a phone, he would be able to contact me right away,” said Jose Lopez, a friend of someone who works at the Indianapolis FedEx facility. “Even if it’s a message with one letter, you know he is living.”

The company has said it is reviewing the policy in the aftermath of the mass shooting that took place on Thursday night.
