was on the scene of a mass shooting in california, once the subject was engaged by law enforcement, the suspect turned the gun on himself and killed himself. we just don't know what was going through his mind, whether he realized the jig p gig wgig . in that moment, even if someone's coming in here with in a depraved intent to kill himself or go down fighting, it appears that was a change of heart on his part. a lot of that will come from that interview when authorities will try to glean from him what was going through his mind and try to recreate what happened. >> you believe he didn't kill himself and didn't fire on law enforcement because he wants to be heard, is that right? >> actually, it was mr. matthews that made that comment, which i found was interesting. if that's the case, certainly he'll be talking to those investigators that are interviewing him right now.
