Caller saying Battlefield Sunoco is a quarter mile and visible from the battlefield. In keeping with the park theory, a sniper could have stationed himself on the Manassas Battlefield to take someone out at the Sunoco.The Sunoco sign may be visible, it's huge! But there's a big I-66 in between the Sunoco and the Battlefield.
Another caller refutes the battlefield scenario and says the shot would have been fired from the Home Depot parking lot.
