as for the weapon, we're told that he bought that 45 caliber semiautomatic smith and wesson handgun off post at the same gun store where nadal hasan bought his weapon before the shooting here the first time around back in 2009. he apparently, lopez did not register that weapon with fort hood officials like he was supposed to. of course, he brought that weapon on post yesterday afternoon about 4:00 when he began that shooting spree and, greta, that shooting spree ended when a female military police officer confronted lopez. he put his hands up, then reached for the gun under his jacket. when the female police officer drew her weapon and fired, she says lopez put his gun to his head and pulled the trigger and ended his own life. greta? >> rick, thank you. and specialist ivan lopez is originally from puerto rico and served in the puerto rico national guard as rick just said. jesus santana served with lopez. evidence joins us. good evening, sir. >> good afternoon, ma'am. >> you can tell me, you know, i'm sure -- you obviously know the news. what did you think when you heard that ivan, someo

described yesterday, put his hands up, then went down and underneath his jacket he pulled out the 45 caliber smith & wesson weapon. at which time she saw that, interpreted that as a threat, and then engaged him with small arms fire, at which time the did a self-inflicted gunshot wound. i doubt it based on her rank, but i don't know the answer to that. [indiscernible] >> yes. i'm sorry? yes. close. [indiscernible] >> at this point i would like not to shed any light on that as it is being fully developed as part of the investigation. let me go on this side. that would be real speculation and i'm not going to engage in that. we are looking at all the factors that you would suspect we are looking at, everything from finance to medical, personal relationships, marital issues, family health issues, we are looking at all of that. did she strike him? i don't have the full autopsy report at this time so i don't other than the self-inflicted gunshot wound to the head.

this is the place that he bought the gun, that .45 caliber smith & wesson, called guns galore.hooter bought his weapons and the owner of this store says another one of the terrorist, private first class abdo, tried to buy a lot of gun powder there. it was alarming, he said, and so the owner stopped him from doing so. that was in 2011. this as more and more military members like captain hegseth want soldiers to be allowed to carry guns on to bases. >> more staff duty nco's, more officers carrying on a regular basis, on a concerted rotation. anywhere you go where everybody knows everybody is not armed, that makes everyone obviously more vulnerable. in this particular case, had someone else been carrying at that facility, maybe something would have stopped. do i think there need to be more people equipped and armed to do that? yes. >> reporter: brian, steve and elisabeth, he bought it legally, but he wasn't allowed to have it on the post. >> that's right. he was able to murder three people and over a dozen were injured. what's the status of their injuries right now? >> reporter: i

but we do know that he bought the gun legally that was used in the rampage it was a forty five caliber smith and wesson that he had bought in nearby killeen and our own we don't have a lot of time yet but i do want to go quickly back to the root cause of this because if you look at what happened in two thousand and nine with nidal hasan who was the perpetrator of that attack he was an army psychiatrist dealing with soldiers coming back from war coming back from iraq he was also like likely dealing with some form of p.t.s.d. can you talk briefly about this mental illness and how pervasive it's really become more generally. sure well the investigation into the most recent shooting yesterday no motive yet so no word if p.t.s.d. or his mental illness had anything to do with it but yeah p.t.s.d. suicide psychological disorders a huge epidemic in the military a study by the national academy of sciences just a couple of years ago found that nearly a million veterans are suffering from some sort of psychological disorder and some of them have multiple psychological disorders so after a decade of war

now, smith claims she laughed after his rifle jammed so he grabbed another gun and shot her again. he then said he finished her off with a shot under her chin because a .22 caliberevolver quote doesn't go through bone very well. smith left both bodies in his basement, says he did not try to contact police until a day later because he says he didn't want to screw up their thanksgiving break. those audio recordings played in court just yesterday. and today the jury heard separate audio from inside the man's home. he says he'd set up the recording devices to protect his house from burglary. jurors reportedly heard several gun shots. at one point the suspect told one of the teens "you're dead." the shooting victims were cousins, both were unarmed. but investigators say the victims were linked to a few other local robberies. under minnesota law, this is important now, a person may use deadly force to prevent a felony from taking place inside of his or her home. authorities have said that smith still went too far, shooting the teens in the head after they no longer posed a threat. now, annie young joins us now with more on this. she's the defense attorney and a former

the alleged shooter, specialist ivan lopez, initially opened fire with a smith and wes s wesson .45 caliberun over a two-city block area. we do have credible information he was involved in a verbal altercation with soldiers from his unit just prior to him allegedly opening fire. the subject then proceeded to travel to two other nearby buildings, entering those locations and opening fire. in transit to those locations, while in his personal vehicle, he indiscriminately fired at other soldiers while moving from one location to another. at this time we are still gathering evidence and processing a very large crime scene so we will not be giving you a time step-by-step timeline of the activity for the investigation. the alleged shooter then encountered a responding military police officer and approached her. subsequently there was a verbal exchange between the two. the military police officer drew her assigned firearm and fired one round when the subject brandished his weapon. we do not believe the subject was struck, but we are currently confirming that fact with the armed forces medical exami
