Reporter mateens exwife was asked about his sexuality on cnn late monday. Do you think reporter the fbi tells nbc news that investigators are checking out the claims which only add to an already complicated corps trt of the 29 year old. He told coworkers he had family connections with al qaeda and that he was a member of the Terror Group Hezbollah triggering an investigation in 2013. But the case was eventually dropped which meant when mateen went to st. Lucie shooting center he was no longer on the watch list. Unfortunately, hes evil. We happen to be the gun store he picked. There is nothing else i can say. Reporter questions are being asked about how a man who was once on a terror watch list can so easily buy a gun. A former atf official is recoen out when anyone who has been investigated for terrorism tries to buy a gun. We are learning more about the 49 victims as tributes to them grow around the world. Craig melvin has that story. Reporter victims range in age from 18 to 50.

Thanks. Lets bring in former assistant director with fbi. Lets talk about the gunman reportedly visiting the nightclub in the past and may have profiles in multitude of gay messaging apps. What do you make of that . When i think about that from an investigative perspective. Is he doing reconnaissance, looking at how the nightclub is set up, how many people are there . From a motivational perspective, is he struggling with his own sexual identitynd is there conflict with his rio belief. Incredible contradiction his dad saying perhaps what triggered his outrage against the Gay Community was saying two men kissing weeks prior. Is this plotting or a smoke screen . When you think about it is he looking to infiltrate the community or is he going through this personal issue. The investigation right now centers on the people who knew him best so it may be the father, his current wife who according to some reports is not cooperating with police. How is that figuring into the investigation right now . I think the motivational perspective is so important right now. Fbi, local Law Enforcement want to find out what was behind this, what caused this. While they are focussing on this act they are looking at the broader potential conspiracy if there are others still looking at that area. Can i ask you a a lot of people posing the question about what happened after the shooting began at that club and wondering out loud why the police waited three hours to actually enter that club. There was confrontation between the Police Officer offduty. Can you shed light on that . Tactically when you think about Tactical Teams there is a shooting, he shoots a number of people. My understanding is there is communication between him and the police. You have this point when the Tactical Team wants to save lives. If they are now engaging with him they are trying to collect intelligence and talk him out of there and get him to release hostages all the while there is imminent death going to occur. While negotiating intelligence said this is going to go bad and another piece of this is policy piece. There is a lot of next day quarterbacking. People looking at what the fbi did, having interviewed the suspect three times and according to fbi director they put him under surveillance. He was on a terrorist list. What does it say that the case gets closed and he is able to buy a weapon . Does that suggest that maybe something needs to change in terms of policy . Here is what it says. This is an incredible challenge for Law Enforcement. After ten months they were not able to obtain enough information to take him off the street. The fbi is looking for a needle in a stack of needles. You cannot make a determination when the switch is flipped. He moved from not exhibiting direct violence to killing 50 people.
