From another board...
"Channel 5 in OKC interviewed a man who said he called police after he heard a very loud explosion.He said that after the explosion the smell of burnt gun powder hung heavy in the air.
Police have apparently cordon off an area at or near the Indian Meridian School in the Choctaw area.
More details will follow after the football game"
Another football game? Can anyone say soft targets?
If it smells like gun powder I'm betting someone dropped a lit cig in the box of post-game fireworks. No modern explosive used blasting pros smells like gunpowder.
One wonders if the "smell of gunpowder" report is correct, or what short of gunpowder the person meant. No burnt or scorch marks found could indicate something like TATP, which doesn't heat up much. You'll note that there were no large marks or lots of smoke involved with the "lone suicide" at the Oct. 1 game either. Just thinking in print.
