ORLANDO, Fla. -- A Disney World worker was killed Monday after a utility vehicle rolled on top of him, according to a report from the Orange County Sheriff's Office. 

Juan Alberto Ojeda, 33, was working on the vehicle's battery prior to the accident. 

Shortly after 9 a.m., deputies responded to 1153 Century Drive, a backstage area between Pop Century and Caribbean Beach resorts that's used for vehicle maintenance.

Danny Vasquez, another Disney worker, told deputies he was showing a new employee around the area, when he saw the accident 20 yards away.

Vasquez said he heard "a screeching sound" before seeing the utility vehicle drive onto a curb and then come down on top of Ojeda.

Vasquez and Josh Willner, the new hire, tried to lift the vehicle off of Ojeda, but it was too heavy, the report said.

Ojeda asked the men to back the vehicle off of him, but they didn't, fearing it would cause further injury, according to the report.

Reedy Creek Fire Department responded to the scene and engaged the vehicle's emergency brake and began rescue procedures.

Emergency responders lifted the vehicle off of Ojeda, but he was declared dead just before 9:30 a.m., according to authorities. 

The Occupational and Safety Health Administration was notified of the incident.

Later that day, another worker was injured in a second accident at Disney's Animal Kingdom Lodge. According to the Sheriff's Office, a man fell and injured himself. He called 911 and was transported to Orlando Regional Medial Center.
