A Takoma Park grandmother died Monday after an early morning fire broke out in her sixth-floor apartment, according to Montgomery County fire officials.

Charlotte Wilson, 56, was found in the bedroom of her apartment on Maple Avenue by firefighters who arrived shortly after the fire started about 2:15 a.m., according to Montgomery County Assistant Fire Chief Scott Graham.

The fire had burned out by the time firefighters found Wilson and Wilson’s granddaughter, who was attempting to help her injured grandmother, Graham said.

Wilson was transported to Washington Hospital Center’s burn unit, where she later died of her injuries, he said.

The fire was apparently started by a cigarette that had either fallen or been discarded into a pile of clothing and towels beside the bed, Graham said.

The cigarette was of the “fire safe” type, Graham said, emphasizing that such cigarettes – while safer than the conventional variety – are still not “fire proof.”

The fire caused only about $1,000 in damage to Wilson’s apartment, Graham said.
