There appears to be 3 gas stations at that intersection...starting with the one at the 11 oclock postion and I will refer to it as #1 - then to the one at 3 oclock as #2 and the one at the 7 oclock as #3.
Which gas station did the sniper hit? The one at the #3 position?
The Mobil station is the bottom left. (7 o'clock
ish) and the gas pumps are under the canopy perpendicular to Connecticut Ave (north/south in the photo)
Because of the location of the pumps, I mentioned earlier that the shot had to come from across the street in the large parking lot. My reasoning is that the victim was between the gas pump island and his vehicle pumping gas and the gas pump blocks one direction, the car blocks the other and the gas station/convenience store blocks the third leaving the parking lot as the only option.
What is also interesting to note is that the building in the lower end of the parking lot is a bank.
Unfortunately, the drive thru is on the right side where cameras would be trained away from where I suspect the shooter was located. I'm pretty sure the police would have noted the bank and checked any tapes they had.
But, I am thinking simple on this one. Back the van up in one of those spaces looking out over the gas station, take a minute to get settled, pick a target, one last check to make sure no passers-by, pull the trigger, close the window and off he goes. Of course he will exit the lot at the bottom of the lot by the bank, make a right turn and take a good long look at his handiwork as he drives by. Then it's through the light, left on Georgia, next stop, Leisure World!
