A 91-year-old man has died from burns after his clothes caught fire while he was cooking at a stove in the kitchen of his McLean apartment Thursday night, Fairfax County fire officials said.

Carroll Adams, who lived alone, succumbed early Friday morning after he suffered burns over 40 percent of his body, said Dan Schmidt, a spokesman for the fire department.

Firefighters responded to the scene in the 1800 block of Old Meadow Road around 9:40 p.m., but the flames had already been doused, Schmidt said.

“There was a neighbor who heard the man call for help,” Schmidt said. ”The neighbor put out the flames on the individual.”

Firefighters treated the man at the scene and then transported him to the burn center at Washington Hospital Center, where he died, Schmidt said.

The death marks the first fire fatality of the year in Fairfax County. There were no such deaths last year — a first in the history of the fire department.
