How did this individual come to possess such strong explosives? Will the FBI release the name of the explosive device? Shouldn't they know by now? This is a very strange case.
"The blast happened shortly after 7:30 p.m. on the South Oval, across the street from the Gaylord Family-Oklahoma Memorial Stadium, where more than 80,000 people were watching the OU-Kansas State football game. One person who responded to the scene said she heard the blast from four miles away."

Well, he had a message in his fraternity meetings about some ammo from ebay. He might have opened some bullets and poured the black powder in a tube.
