Late details now from Ed Lavandera.</s>ED LAVANDERA, CNN CORRESPONDENT (voice-over): Omar Mateen was angry as he packed a bag with his guns and then made the two-hour drive from his home to the Pulse night club in Orlando. That's what law enforcement sources say Noor Salman, Mateen's wife has told investigators. Salman says she pleaded with Mateen not to leave and grabbed him by the arm. She says she didn't know he was planning to kill dozens of people at the club. She also never called police to report what was happening. Law enforcement also says the day before the attack, Mateen purchased three plane tickets for himself, his wife and child to fly to California. On Tuesday, Attorney General Loretta Lynch visited the shooting site but refused to say if criminal charges would be brought against Salman.</s>LAVANDERA: Are you convinced that Omar Mateen's wife did not know about this attack, or should she have done more to stop it?</s>LORETTA LYNCH, U.S.  ATTORNEY GENERAL: Well, we're not going to speak about anyone else's role in this right now while we are investigating the matter.

He may have been checking the building security that night. Mateen left the club, came back two hours later and unleashed the violent shooting spree. Investigators are trying to figure out what Mateen was doing during those two hours.</s>RON HOPPER, FBI ORLANDO ASSISTANT SPECIAL AGENT: That is why we're asking for anybody and everybody that had any contact with this individual to come forward --</s>HOPPER: -- so we can piece that information together.</s>LAVANDERA: Attorney General Lynch says investigators are still working to determine whether Mateen acted out solely as a self- radicalized extremist or if he was driven by homophobia.</s>LYNCH: We do feel that as we continue to build a timeline and a chronology and to build his life, that we will be able to determine this I cannot tell you definitively that we will ever narrow it down to one motivation.</s>LAVANDERA: Investigators have finished collecting evidence at the Pulse Nightclub, the roads have opened up in a small memorial of flowers and tributes is already being left under the club's marquee -- Ed Lavandera, CNN, Orlando, Florida.</s>WALKER: An American teenager is under arrest for attempting to provide material support to ISIS and travel overseas to join the terror organization.</s>VAUSE: FBI agents took 18-year-old Akram Musleh into custody in Indiana.
