FedEx Corp. says a 19-year-old employee injured in an accident Wednesday morning at its world hub in Memphis has died.

Chandler's father told FOX13 News Tuesday night started out as any other overnight shift at the FedEx hub for his son, who worked as a material handler. Sometime after midnight though, Chandler was injured by some type of loader and rushed to the Regional One Medical Center with severe injuries. Warren had emergency surgery but his heart stopped during recovery.

His father, Chris Warren, said his son had a collapsed lung and internal bleeding. Doctors were trying to stabilize him when his heart stopped. He was right by his side holding his hand when his son passed away.

Chris Warren received the disturbing phone call in the middle of the night and rushed to Regional One in the medical district. He says his son's injuries were worse than he could ever have imagined.

"I got to hold his hand, pray with him, and it was gut wrenching , heartbreaking, something no one should ever have to see or go through," Chris Warren said."He looked like nothing I'd ever seen before," Chandler's father said. "There were more tubes than I have ever seen in one person coming out of him."

His father says Chandler had major injuries to his shoulder, a collapsed lung and some internal bleeding. Doctors took him into surgery and were trying to stabilize him enough to take him into the ICU, but that is when Chandler's heart stopped, with his father by his side.

Chris said his son had been inspired to go to aircraft maintenance school and was about to get his paperwork started. The two just talking about this on Tuesday before Chandler went to work.

"He loved it, he saw this as his ticket to get to wherever he wanted to get to, to do what he loved. He loved working with his hands," Chris said.

He said his son had only recently started working at FedEx's world hub after moving to Memphis from Florida, where he was born.

According to his Facebook page, Chandler was a material handler. Chandler's father said his son loved his job and saw it as a career path. His father said he had also recently purchased a new car.

FedEx spokesman Scott Fiedler said the company is cooperating with authorities who are investigating.

"I can confirm that one of our team members suffered a fatal injury early this morning at the FedEx Memphis World Hub," Fielder said in a statement. "Our thoughts and prayers are with his family and friends during this difficult time. We are working with authorities as they investigate the accident."

His father says FedEx will be covering Chandler's funeral costs. He didn't have benefits yet as he was still in his trial period as a new employee. His father is hoping for an investigation as to what led to his son's death. FedEx would not comment on any other specifics.

The Occupational Health and Safety Administration investigates workplace incidents and has yet to comment on today's tragic accident.
