Announcer this morning ice welcome to cbs this morning. Ing icest we have alarminginste airliner in the alps. Andreas lubitz is accused of rehearsing the maneuver on an earlier flight the same day. Charlie dagata is in london with details. Charlie, good morning. Reporter good morning, investigators say on the previous flight that morning on a trip to barcelona, Andreas Lubitz repeatedly set the aircraft into a descent and then brought it up again. This is on the same airbus a320 jet that crashed into the mountainside on the way back to germany. Reports said the main pilot appeared to have left the cabin during that flight as well. Cockpit data shows he put the plane into a descent mode five times in a four and a half minute period. The data from this earlier flight was found in one of the two black boxes from the crashed aircraft. Investigators said the plane was already on descent and didnt nose down sharply during that period suggesting that passengers and crew may not have noticed. The chief investigator said he couldnt speculate what was happening inside lubitzs head only that he changed those controls for the minimum setting of 100 feet and he did it several times. Charlie dagata, very disturbing twist. Charlie reporting from london this morning. New clues may explain why two men attacked a texas exhibit featuring cartoons of the pro prophet mohammed. A man who joined somali fighters is linked to one of them. He committed on twitter with Elton Simpson. Watchdog groups that track online terror threats describe him as an important recruiter for isis. U. S. Investigators are still checking out isis claim of responsibility for sundays attack in garland, texas. Jeff pegues is in washington where officials confirm they were tracking simpson before the shooting. Jeff, good morning. Good morning. In the last month, something sparked Law Enforcements interest in Elton Simpson. Its not clear exactly what that was, but the arizona man had multiple social media accounts and tweeted out hints of the attack before it was set in motion. Investigators are trying to determine if Elton Simpson and nadir soofi received specific directions from isis or whether they were simply inspired by the terrorist organization to carry out attacks in the u. S. One antiterror watch group says the evidence is online in twitter exchanges between simpson and a man named mujaheed misky. David ibsen is the counterextremisms project executive director. He recruits via social media, particularly in his case twitter. Just last month, he tweeted the brothers from the Charlie Hebdo attack did their part. Its time for brothers in the u. S. To do their part. Simpson tweeted back when will they ever learn . They are planning on selecting the best picture drawn in texas. Rasullallah is the prophet mohammed. I characterize that as being evidence of incitement and propagandizing on behalf of extremist groups targeted to individuals located in the u. S. Compelling them and encouraging them to commit acts of violence in the u. S. Against americans. Reporter before the attack on sunday, simpson pledged allegiance to isis and wrote may allah accept us as mujahadeen. Simpson was the subject of a terrorism investigation in 2006 and was convicted in 2011 of lying to the fbi about wanting to join terrorists in somalia. He received three years probation. I wonder if he just snapped. Reporter Christina Sitton represented him in that case. It never occurred to me he would actually follow through on it. Reporter a Law Enforcement official says simpson and soofi were not considered high priority threats. They are like several thousand individuals u. S. Law enforcement is following across all 50 states. Charlie . Thanks, jeff. Also in washington, with cbs news Senior Security contributor michael morrell. He is a former cia deputy director. Michael, good morning. Let me begin with your assessment of these twitter exchanges. So, charlie, no doubt in my mind that given these twitter exchanges, and there also appears to be some exchanges with an individual in syria as well, that these are what inspired these guys to attempt this attack. Inspired not directed. Inspired not directed. Does it make a difference . Sure i think it does. Theres both a positive and negative, i think. The negative is that a directed a tack gives you the opportunity to do something bigger. Because you can put more individuals around it folks in a mall for example. But the positive is that a directed attack theres communication between the leadership of the group and the terrorist so it gives you an opportunity to detect the attack in advance. Now as you know mike isis has claimed credit for this attack. Do you think that helps them recruit more members here and in other places . Well to recruit folks to raise money you have to conduct successful attacks, gayle, and this attack was not successful. And i think its important to remember that. So im not sure theyre going to get a lot of benefit out of taking credit for this. Mike, the u. S. Has Just Announced itsbounties on the heads of four of those isis leaders. Do those bounties help . Norah, they sure do. They generate an awful lot of information. The vast majority of this information is not particularly useful but every once in a while occasionally you come across a piece of information that makes a big difference in finding these guys. And those people are compensated when that has. Why is the trail so difficult . Its interesting this attack in garland, texas, because theres an electronic trail of tweeting back and forth. Doesnt that make it easier to locate the source of where these leadership are and where theyre conducting their operations from . Its hard to identify the location of a tweeter if they dont want to be found. But there is an awful lot of information in these tweets the, and we have to start mining it. Mike one last kwem. There was a piece in the New York Times today that said that france is taking steps to vastly widen domestic spying. Is that what were going to have to end up doing . You know charlie, the way people think about whether we should do this or not almost always depends on what just happened, right . And these attacks in paris happened. People are willing to do more. Thank you mike morrell. Youre welcome. More Severe Weather threatens parts of the south and midwest today.
