WASHINGTON - The ferocious fire that ravaged a Capitol Hill landmark earlier this month most likely began after an employee dropped a cigarette butt into a bucket in the alley, the Washington Post reports.
The Post, citing two law enforcement officials with direct knowledge of the investigation, says officials believe the fire was accidental.
Investigators have interviewed a 23-year-old employee seen on surveillance video taking a smoke break shortly before the fire was reported, the Post reports.
Investigators tell the Post that the alley space is used to store wooden beams, bags of cement and other supplies for the hardware store.
Officials pinpointed a plastic bucket as the point of origin for the fire, the Post reports.
