I'm afraid I knew it ...

"Smoldering cigarette blamed for fire fatal to Batavia teen" - The Buffalo News, 5/31/08:

BATAVIA -- A smoldering cigarette has been called the probable cause of a fire early Friday that killed a 17-year-old high school student.

Genesee County Emergency Management Services coordinator Timothy J. Yaeger said the victim's mother, Judy Clark, 41, had been smoking in an enclosed porch about half an hour before the fire broke out about 2 a.m. A smoke detector and barking dog awakened Clark and she and another son, 15-year-old Michael Mooney, escaped with minor injuries.

Erik Mooney was found in the house and pronounced dead of smoke inhalation an hour later at United Memorial Medical Center.

The brothers were students at Oakfield-Alabama Central School. Their stepfather, Scott Clark, 47, is a truck driver and was not home at the time.

Nobody dare smoke indoors these days. Or use an ashtray, those filthy things.
