BLITZER: Tonight, there's an important new development in the investigation of last weekend's mass shooting in Texas. The assault- style rifle the gunman used to kill seven people and wound 25 may have been assembled from parts bought separately. Let's bring in our senior justice correspondent Evan Perez. Evan, what are you learning?</s>EVAN PEREZ, CNN SENIOR JUSTICE CORRESPONDENT: Well, Wolf, this is a common trade in the gun business, for people to buy what's known as lower receivers and other accessories and essentially assemble a fully -- a fully assembled AR-15-style rifle, and that's what investigators believe happened here. They believe this -- the alleged seller of this firearm that was used in the Odessa-Midland shootings, that that's what he was doing. He was manufacturing these things in his home. And so earlier this week, there was a search that was done, and the -- and the authorities in -- found evidence that they believe indicates that he was doing this as part of a business. Now, what this does is it means that they can possibly bring charges against him for acting as an unlicensed manufacturer, an unlicensed gun dealer, and so that's what investigators are focusing on right now.</s>BLITZER: Very, very serious development indeed. All right, Evan, thank you. Coming up, there's more news we're following including an airline mechanic goes to court, accused of sabotaging a jet that nearly took off with 150 people aboard.
