This sniper doesn't care who he shoots. He is 90% concerned with setting up an isolated shoot site in close range of normal human activity, with a near perfect isolated escape route. Then and only then does he select a random victim who walks into his crosshairs.
Look for the slick escape routes and remote shoot sites with a line of fire to gas stations etc. That's the way to look for this guy, from the escape route end.
That's very true, but unfortunately, there are so many of those venues.....
Think the police "missed" the possibility of the sniper on foot for part of the scenario.
If this is Sniper No. 1 who "kills" not wounds, he might have been left off in Fredericksburg and traveled northwest (the other traveling northeast to where the kid was "wounded") and we may see a second weapon in play.
We'll see but certainly they know if it was a shotgun or rifle.
Maybe we have another casing??

This guy,to me,is working like a roadhunter that doesn't want to be caught and he needn't worry about returning to collect his "game".
His shooting location and escape route are his main concern because "targets" will be available nearly anywhere he finds suitable for his own safe escape.
