UPDATE: Brandon Scott Hole, the 19-year-old behind the deaths of eight people at a FedEx building in Indianapolis, was a former employee of the facility where the fatal incident took place.

ORIGINAL STORY: A suspect has been identified in the Indianapolis shooting that killed eight people and injured five others on Thursday night (April 15). As NBC reported, authorities confirmed that the suspected gunman was 19-year-old Brandon Scott Hole.

Hole was reportedly known to federal and local authorities as family members previously contacted cops and warned them of his potential for violence. He was also detained and transported to a hospital in May after he reportedly “seized [a] shotgun from [a] dangerous person” and voiced “suicidal ideation.”

As REVOLT previously reported, Hole drove to the FedEx facility near the Indianapolis airport around 11 p.m. and immediately rang fire upon exiting his car.

He killed four people outside of the location and then made his way inside the facility where he fatally shot four others. He took his own life moments after responding officers encountered him on the scene.

According to FBI Special Agent in Charge Paul Keenan, federal agents have already removed evidence from the suspect’s residence for their investigation into the fatal shooting. He said it was too early in the probe to provide a possible motive, but police do not believe the incident was triggered by any altercations and verbal exchanges ahead of the gunfire.

“There was no confrontation with anyone there, no disturbance, no argument,” Craig McCartt, the Indianapolis Police Deputy Chief of Criminal investigations said during a press conference on Friday (April 16). “He just appeared to randomly start shooting.” The whole attack reportedly lasted between one to two minutes.

In addition to the eight fatalities, Hole’s shooting also injured five people. They were transported to a nearby hospital where they were treated for their gunshot wounds. Two people have since been released, while a third remains in critical condition, per a statement from the Indianapolis Metropolitan Police Department.
