Reidout. Ally velshi, msnbc host of velshi and susan de. First we have some breaking news. Lets go to my colleague for the latest developments on the tennessee explosion. Lets go straight to the News Conference ongoing right now, rev. And that is based on the evidence that weve gathered to this point, weve come to the conclusion that an individual named Anthony Warner is the bomber, that he was present when the bomb went off and that he perished in the bombing. We base this conclusion on forensic evidence, including dna evidence that youll hear about as well as evidence that was gathered at the scene of the bombing. Because this was a collaborative effort, what i want to do is turn the microphone over to each of the agency folks here. Theyre going to talk about their agencys role in the investigation and how the evidence they gathered and the tests they conducted e led us to this conclusion. Let me start out by introducing Tennessee Bureau of investigation director david roush. Thank y
