The man who police say fatally shot eight people at a FedEx facility in Indianapolis is a former employee, the company has confirmed.
FedEx spokesperson Bonny Harrison released the information on Friday.
She says company officials cannot speculate on a motive, but are working closely with investigators.
Earlier, authorities identified the suspect as 19-year-old Brandon Scott Hole of Indiana.
Two law enforcement officials briefed on the matter provided the identity to The Associated Press.
The investigators are searching a home in Indianapolis associated with Hole and have seized evidence, including desktop computers and other electronic media, the officials said.
The officials could not discuss the matter publicly and spoke to the AP on condition of anonymity.
The shooting on Thursday night left eight people dead and several wounded.
