The Exxon at South Capitol and I streets has apparently shut down--a correspondent reports that the building is boarded up, and their phone number has been disconnected. Their page on exxonstations.com
says "Temp. Closed", but it would seem odd that a temporary closing would result in a disconnected phone number. I've heard nothing about a sale of that property, but certainly it could be considered a somewhat prime location (although that's a ghastly intersection). Will pass along more as I find out.
From another very on-the-ball correspondent, a link to a DOJ press release
from January detailing that the Exxon's owner pleaded guilty "to fraudulently double-billing government contractors more than $120,000. [Mahmud] Rashid, 46, of Raleigh Lane, Stafford, Virginia, entered a plea of guilty yesterday in United States District Court to one count of wire fraud. According to the terms of the plea agreement, Rashid could be sentenced to between 12 to 18 months of incarceration when he is sentenced before the Honorable Richard J. Leon on June 2, 2006." As my correspondent noted, "this might help shut down your gas station."
