we have with us mary ellen o'toole, an fbi profiler.enforcement analyst, aaron perez, justice correspondent. but i want to start with paul minteri who is with affiliate kynt. what do we know about the suspect and the search for any information that could lead them to a motive? his home. his social media. his family and friends. >> i think they are going to try to retrace back, without officially naming the suspect at this time, look at all of those documents they claim to have in the video that has been widely distributed, although, again, he is unnamed, and try to retrace back what started all of this, what caused this mental mindset to go on this rampage, and who he was targeting. it looked like it was -- it was random, but there may be some indication that -- that there's more specific means of why he was out shooting last night. i can tell you they have a number of investigators from nearby agencies coming in, and they're going over crime scene, tracking the path of the shooter, the number of bullets fired, and whether he had verbal

let's bring in now mary ellen o'toole. plus gayle, author of "anatomy of a killer."ed lines from the pick up artist community. >> you hear a lot of things including rage. this is not that a-typical for people who do ultimately go on to commit violence. i think you have to remember that there are many angry grandiose young men that will never commit violence. that leaves us in a very difficult situation. i think we need to reevaluate those first responders, and they're training for viewing someone that maybe they need to bring a clinician, and what they need to be on a look out for. we now have all of the social media material available. but we don't have a means for first responders looking at that and going one step further. >> all too often, these horrific shootings, there are warning signs, right? why didn't we stop this sooner? why weren't we able to see this, his parents stepped in, they said he needs to be checked. there was a number of clues in his bedroom. talk to us about what law enforcement can and can't do legally. >> this is very frustrating and it is in

. >>> i wanted to bring in mary ellen o'toole, a former senior profiler of the fbi. let me put to you the same question. first of all, we believe, and it's being reported, cnn has been found, that this man had been seeing a therapist, psychiatrist, had been seeking mental health help. he does seem to fit, however, when you look at some of his writings in the diary -- let me just set this up. this is from his diary where he wrote "cruel treatment from women is ten times worse than from men. it made me feel like an insignificant, unworthy little mouse. i felt so small and vulnerable. i couldn't believe this girl was so horrible to me and i thought it was because she viewed me as a loser." there's bullying, isolation, violent video games involved. we've seen it before. >> we have seen it before. we know there are warning behaviors before each of these incidents. these warning behaviors can individually appear to be somewhat benign or maybe better stated pretty typical of a 22-year-old. but it's incumbent upon people that do the threat assessments to take a look at 360 d

jody gold and mary ellen o'toole, retired senior fbi profiler and forensic behavioral consultant.you for being with us. looking at the videos, hearing the evidence, seeing the manifesto, it doesn't seem to me you need to be a forensic expert to see the red flags here. but what jumps out at you as to what needed attention? >> well, what jumped out was what he said in that video in particular, and of course in the manifesto. there were indications that he had both homicidal and suicidal thing. he was tempered in how he presented in that video which to me told me that he was not out of touch with reality. so that made his threats even more likely to occur. it was really the totality of everything he said that jumped out to me with a red flag. >> i'm less impressed with the details of this individual's life. the iron any here is they drive the interest of you at home and yet the frustration of why do we keep seeing these cases. the families tried to get him treechlt. he rejected it. friends said something and saw something, neighbors as well. the cops were called for a wellness check
