The Fulton County Medical Examiner's Office told Channel 2 Action News they are still trying to identify the victim in the death of a man in a burning wheelchair.

Channel 2's Craig Lucie was in southwest Atlanta Monday when investigators returned to search for clues.

Investigators from the Fulton County Medical Examiner's Office met with Grady Health System investigators at the crime scene Monday, trying to get some answers on how the man caught fire.

They pointed out a route showing where the man came from the street, down a ramp and then somehow caught on fire and burned to death.

As soon as Lucie and his photographer pulled out their camera, the investigators left the scene -- and with some trying to cover their faces.

Lucie checked with Atlanta police about the investigation and they said, "The cause and manner of death is pending an autopsy."

Saturday, investigators told Channel 2 Action News they did not find anything indicating the fire was suspicious.

Witnesses said they spotted the flames that nearly caught a Family Dollar store on fire as well at about 5 p.m. along Metropolitan Parkway.

"As high as the building. On the side 15 to 20 feet," witness Bernard Arnold said, describing the flames.

Arnold said an officer, at first, didn't think it was that serious.

"They was saying there was a wheelchair on fire, but nothing else," Arnold said.

It wasn't until after firefighters extinguished the flames that they found the man's body in the wheelchair.

Many in the area told Lucie they find this case very strange.

"It just seems a little suspect to me," Arnold said.

Firefighters said they didn't smell any gasoline or flammable material that may have started the fire.
