Go to Google maps. The satellite photo and streets idea photo show a “nipple” on top. The shadow is the shadow from the nipple.
I keep coming back to that the local sniper team were in the second floor of the building that overlooked the building where the shooter was. Another story posted was they got pulled out to search for the shooter. If that story is true who made that call, was there nobody left at that sniper post to view that roof, or was “Greg” in there and somehow tunnel visioned down scope? That sniper position on the second floor of the AGR building is the key to what happened.
Gotcha. Thanks.
