many people take ambien. they don't go out and kill themselves and kill other people. unstable mental health can be one of the risk factors for someone deciding that that's what they're going to do, but it's not the only risk factor. our concern has been over the last 20 years that we not stigmatize people that have serious mental health issues because most people with mental health issues, they're not violent. >> tom, you've investigated these kinds of mass killings over the years. you agree with mary ellen? >> absolutely. >> tell us what would trigger someone who seemingly was normal, served in the u.s. military, served in iraq, spent a year with the u.s. military serving in sinai, part of that international peacekeeping operation that the u.s. is involved in, served in the puerto rico national guard and enlisted, became a full-time u.s. army soldier. how does that develop into a massacre like this? >> well, it's hard to tell what becomes the last straw in that person's mind. and often, the unfortunate problem is that in many of these cases they take that to the grav

and he was prescribed a number of drugs to address those, including ambien. he was seen just last month by a psychiatrist. he was fully examined. as of this morning, we had no indication on the record of that examination that there was any sign of likely violence, either to himself or others, and no suicidal ideation. >> of course as they continue to investigate what may have motivated this action by this shooter, they will be talking to his friend and relatives, and they have already interviewed his wife last night, which must be a point of deep distress and sorrow for her. her husband allegedly involved in murder and hurting of others, and killing himself. and she has to answer to whatever it is that she may have observed in the final moments of his life. >> we should say that we're talking about a suspected shooter that has been named by a congressman as 34-year-old ivan lopez, but th army has not officially confirmed that. as you said, we're standing by right now to see a live press conference and it looks like that is starting to get underway. this is wh

ambien is incredibly addictive.ave to say that. >> addictive psychologically like marijuana but the doctor says it's not physically addictive. i know this one firsthand. it's horribly addictive. very challenging times. psychological versus physical. i think it actually can exacerbate any other mental issues going on. >> sure. >> is there more stress today than there was, say, 30 years ago? i mean, with the explosion of drugs being prescribed more stress in america? >> i think stress fills up whatever vacuum that you have going on. i don't know that we could say it's because there is more stress. i think we are better at diagnosis more willing to talk about issues. >> your willing to take drugs. >> more willing to take drugs and less tolerant of uncomfortable feel. we want a quick fix. we want a quick fix. >> tough it out. >> maybe we have to do things about our sleep like at a regular time and so on so we sleep better instead of popping a pill. >> isn't it about gratification? if you are not filing well. everybody e

he was prescribed a number of drugs to address those including ambien. he was seen just last month by a psychiatrist. he was fully examined. as of this morning we had no indication on the record of that examination that there was any sign of likely violence either to himself or to others. no suicidal ideation so the plan forward was to just continue to monitor and to treat him as deemed appropriate. >> now when so many heard this news last night, the first reaction was not here not again. this is the same military facility where an officer killed 13 in 2009. president barack obama says this deadly repeat is heartbreaking. >> any shooting is troubling. obviously this reopens the pain of what happened at ft. hood five years ago. we know these families. we know their incredible service to our country and sacrifices they make. obviously our thoughts and prayers are with the entire community. we are going to do everything we can to make sure the community at ft. hood has what it needs to deal with the current situation but also any potential after math. >> as

was on some sort of anti-depressant, and then we heard in more detail today he was also prescribed ambien for sleep disorders. a guy who was suffering from depression and anxiety, according to authorities and was apparently claiming to have ptsd but that had not been officially determined. >> hey, rick, the -- the situation around post-traumatic stress disorder seems a little confusing to me. he had been looked at for having that or was in fact being treated for that because he was seeing a psychiatrist, correct? >> reporter: was seeing a psychiatrist, was complaining of mental issues, and apparently among those issues he believed he may have had post-traumatic stress disorder. he claims he suffered a traumatic brain injury in iraq at the end of 2011, but the army says there's absolutely no record of lopez suffering any combat injury, no record of him having a head injury and no confirmation he had ptsd. they say it's a very lengthy process to determine if someone does have that condition and that they were looking at him, diagnosing him to see if he did, but they hadn't yet concluded the

and we are told, we know there may have been other medications, as well, but ambien is one that officialsaid that he was taking. dr. xenakis, when you look at someone in the military who is being treated for, again, a variety of mental health an behavioral issues, and they mentioned depression and anxiety, one question that comes to mind is at what point does this disqualify someone from serving in the military? >> well, theñr whole-- there is a set of guidelines and regulations having to do with who is he vig-- eligible or should be considered for separation for medical reasons. and they've been around for decades. and it really boils down to does their medical illness or injury impair their duty performance. and the focus is on the duty. and does the problem mean that they can't do their job and or that they are going to put other soldiers in danger and not finish, complete the mission. >> woodruff: staying with you, dr. xenakis, what does it is a to you that he was being evaluated for ptsd, post traumatic stress disorder, and that there was no record of a traumatic brain injury? >> th

he was on drugs and on ambien. they were monitoring him. what was the army not doing in your opinion? >> just because they are saying they are doing these things, doesn't mean it was true. they are differently. they were just a normal soldier sucking it up. >> how are you treated differently. >> basically you are not good enough. you are different. they can perform the duties about freaking out. maybe that soldier department do the same thing another soldier did. >> that's something that people are overlooking and say those people are being selfish. they are reaching out. they are going to try to get out. you will end up screwing yourself because you are left with nothing. they will not have the benefits to take care of you. who is to say you make it's the harsh reality you will be stressed out and be unhappy. it sucks that you have to live every day regretting and joining something that you thought would have been good. it's not like this at every post. i'm a military brat and i loved the places i have gone to. it doesn't make any sense ho

also, he is like walking ambien. when was watching that, he has a special aspied's spider-man but shoots out ambien. >> but he does the opposite on dana. walking caffeine on dana. >> i'm so calm, cool collected at 4:00. >> can i not throw in the towel just yet? >> of course you don't agree with his numbers. >> let's talk about this for a second. for six months, from november through the end of march, they had no idea how many were signing up. not a single clue. sebelius went on jon stewart, got destroyed for not knowing, even ballpark. the minute the program ends they know it's 7.1 million, a month later they know it's 8 million, "x" percentage of young people. this is all bull. >> i agree. >> they're doing what bob beckel does to us all the time. prove it. >> pulls a number from anywhere. >> pardon me. i was just -- it's groundhog day. >> where does he get the numbers? >> i don't know where he gets the numbers. the fact of the matter is it's working, the numbers are good. you guys have staked your stake on something

he was taking antidepressants and the drug ambien.ng evaluated for post-traumatic stress disorder, though it's important to note he was not officially diagnosed with ptsd. he was simply being evaluated, going through the process. now, we also heard about a possible confrontation on post that could have played factor prior to the shooting. i want you to take a listen to this. >> we're looking into that, trying to figure out what the trigger event was. it was mentioned yesterday there may have been a verbal altercation with another soldier or soldiers, and there's a strong possibility that that, in fact, immediately preceded the shooting. but we do not have that definitively at this point, but we do have strong indications of that. >> reporter: three people were killed in this shooting, 16 injured overall, but we've learned that of the 16, 3 who were in critical condition have been upgraded to serious condition. but again, a terrible situation here that played out, we saw, five years ago. same situation. >> yeah, that is just -- i mean,

ambien as we know, many reports that it has a lot of effects, a lot of side effects.know if that was part of it here. in the military, over the years, there have been stronger and stronger controls on multiple prescription drugs for troops, especially those suffering from post-traumatic stress or traumatic brain jury. it's been an issue. i feel confident that's going to be one area they're going to look at. what drugs was he taking? what interactions were there? was there potential for abuse of prescription drugs? they're going to look at all these issues about behavior and what was noticed. one of the most interesting things perhaps since the 2009 incident at ft. hood is is military came to understand it didn't have enough assessment of soldiers when they came home from deployment about whether they might be indicators if you will they could engage in violent behavior. there was an effort to try and work on that and in post deployment evaluations really get a better look at their mental health situation. again, for this soldier he was in iraq four months at the end o

we know also that he was taking multiple prescription medications, including ambien. so these are all of the medical factors that will be looked at. but what is on the table here, unspoken, is the military regulations and laws about all of this. if someone is undergoing military mental health counseling and treatment, their mental health provider perhaps missed something here because they are required to ask the person, are you a harm to yourself or others, are you planning to buy a weapon? do you have a weapon? we know that he bought a weapon on march 1st. we know that he passed a psychiatric evaluation. what we do not know is what the course of events were. did he see a military mental health provider after he bought that weapon? we just don't know and that's the real -- maybe one of the real unanswered questions, how did all of this get missed. >> all facts to be determined going forward. barbara starr at the pentagon, thank you for that. >>> we're going to take a break and shift gears. we have huge breaking news from the world of entertainment. you'll hear that ne

he was prescribed a number of drugs to address those, including ambien. just last month by a psychiatrist. he was fully examined, and as of this morning, we had no indication on the record of that examination that there was any sign of likely violence, either to himself or to others. >> and news of the shooting spread quickly at fort hood. one woman said she was with the gunman's wife as the news broke last night. >> i happened to look upstairs, see ethe wife coming outside, hysterical's he liked like she had been crying. i went to console her because i knew her husband was a soldier and i told her everything would be okay. she hasn't heard from him since 3:00. so -- we stayed with her, to make sure she was okay, and -- next thing you know, we hear it on the news, they announced his name and she just breaks down. >> the shootings, of course, brought back vivid memories of 2009 when army

he was prescribed a number of drugs to address those, including ambien. he was seen just last month by a psychiatrist. he was fully exam indi, an exam. and as of this morning, we had no indication on the record of that examination that there was no sign of likely violence, either to himself or suicide. >> secretary mchugh also said that based on his interviews in iraq, he had no encounters in combat that would suggest that he suffered any kind of brain injuries. >> and they said that they don't believe that he had ties to my extremist organizations. and i want to ask you, how does the 2009 shooting change the security measures at fort hood. and how did that change the response to yesterday's event. >> in 2009, the shooting by major hasan resulted in changes around the world. one of the results of that after the shooting, there was a report put out in 2010, and it called for an update in notification methods, getting the word out to the base, and that was done yesterday. but apparently what did not work was another recommendation on that 2010 report on how

this shooter ivan lopez was on a cocktail of anti-depressants and ambien and showed extreme anger on his facebook page, green light and finger ready. that's translated to go time, locked and loaded. do we ned to know more of what's going inside their medicine cabinets and less inside their holsters? >> these don't come about because the availability of guns but the mental health of a couple of real monsters. no one goes on a killing rampage simply because there was a gun around. they go on it because they are seriously disturbed, seriously deranged people. i think more guns, the more widespread availability of guns in movie theaters, military bases, in schools could have stopped some of these madmen before they were able to kill as many as they did. mental health is the explanation of these terrible tragedies. not availability of guns. >> all these young men were at least reportedly on some anti-depressants and seeing counselors for depression and other ailments. >> the statistics tell us approximately 46.4% of the people in the you'd at some point in their lifetime are going to suff

fueled by ambien and outraged on facebook, we look inside the mind of the fort hood shooter. him to be their ambassador to the united nations, believe it or not. >> you know, it's dismaying and even more dismaying is this is yet another indication of just how radical, how extreme, how anti-american iran is. >> why won't the obama administration deny this guy a visa to the united states? that is the big question on this friday morning. >>> and many liberals claim to be tolerant. so why did a high profile ceo just have to resign for believing in the sanctity of marriage from a company he created? we report. you decide. final hour of the week because mornings are better with friends. >> hi, this is sarah palin. you're watching "fox & friends." my favorite show. >> really? >> she's in the news today. >> sure is. >> how is she in the news? >> because dave letterman is calling it quits. now she's got some advice for congress. >> i know she started the week on jimmy fallon on the "tonight show." >> first a fox news alert for you. did an argument with another soldier -- did that argu

. >> reporter: including ambien, for sleep. and while he saw that psychiatrist, as recently as last month, no signs of what was to come. and even though lopez was being tracked for signs of posttraumatic stress, he had not been diagnosed and fully treated. >> there's not a diagnosis that you make on one appointment. >> reporter: even if he had, it's unclear whether he would have stood out. the military, today, dealing with a staggering number in its ranks. one in five, with mental issues. more than double the civilian population. almost always, it's about depression, not violence. >> depression, anxiety, ptsd, those are kind of on the mild end of the scale. >> reporter: this happens just as a time when the army is trying hard to destigmatize those who report symptoms of posttraumatic stress. but the military is struggling to keep up with the number of cases. a number that is sure to grow. diane? >> thank you so much, martha raddatz. >>> and abc senior justice correspondent, pierre thomas, is also standing by, with the latest on

he was on medication for anxiety and depression, ambien to help him sleep. also they are looking at clues from social media. as we know that is something they look at closely in this day and age. on his facebook page, the 34-year-old army specialist posted this. back at the very beginning of march, quote, i was robbed last night by two flacos. guys, the translation there. green light and finger ready. as easy as that. he went on to say i have just lost my inner peace, full of hatred. i think this time the devil will take me. some of his friends have also alluded to the fact he started to resent the army in november of last year when his mother died in puerto rico and lopez claimed he could not get sufficient time off to go there and pay his respects. he also lost his grandfather as well. all of this information, things investigators are looking at trying to put the pieces of the puzzle together, gretchen. >> thank you. >>> looks like march's weather didn't have much of an impact on job. u.s. employers added 192,000 last month, less than what economists are p

including ambien. he is a principle investigator and a ten year study, funded by the department of defense. he is also the director of the moods disorder clinic. good to have you with us. according to the veterans administration, between 11 and 20% of returning iran and afghanistan war veterans have come home with ptsd, and close to one quarter million have been treated over the past ten years. i think you would agree that people that have ptsd are rarely violent toward other people? >> antonio, the real message here, is that the -- when someone someone suicide, and almost all instants, 85% of people whod is, they have a psychiatric illness. and it's not necessarily ptsd. you know ptsd is rarely occurred by itself. in almost all instances ptsd is accompanied by other things. like depression, or anxiety, or alcohol abuse. so this kind of complexity is usually not a part of the story here. and people to have to understand that this is much more complex situation than is being talked about. >> well, in fa

he was described a number of drugs to address those, including ambien.seen just last month by a psychiatrist. he was fully examined, and as of this morning, we had no indication on the record of that examination that there was any sign of likely violence, either to himself or to others. >> dr. lieberman, who does that sound to you? that someone who ended up doing this showed no indication in any of the diagnoses that were going on or any of the treatment procedures going on that this might happen. >> someone who does this isn't in their right mind. but on the other hand, there was no pyre indication by virtue of past psychiatric history or abnormal or unusual behavior, much less tendency towards violence that suggested he was capable of this. so it's a little mysterious, and one could say the military did everything that one would expect and is appropriate, and this was just one of these rare accidents or happens of hate. on the other hand, this is another de ja vu all over again, because this has happened repeatedly. so we have to understand that someth

we know he was on many different medications, antidepressants, taking the drug ambien, a sleep medication also have to remember, he was being evaluated for ptsd, not officially diagnosed. all will be taken into consideration, wolf, as investigators try to understand what led up to the shooting. one interesting thing that they will be looking into is a verbal altercation that happened just before the shooting. they will try to understand how that played into this, if it might have been an escalating point leading up to the shooting. >> and they have identified the three someters soldiers shot and killed by lopez, right? >> reporter: wolf, i want to read these names. they have learned them. timothy owens, carlos rodriguez, danny ferguson. and we know something about mr. ferguson. we have heard from his fiancee. she spoke with affiliate wtsp, and she described him as a person who loved sports. he loved football, loved basketball, also loved serving his country. and in the moments when this happened, two days ago, when lopez came on post, and fired his weapon, killing three people, injuring 1

. >> what cities do you have, though, that address prescription drugs and ambien and valium, and ally can't i ever finish, sean? you know, you address how it is marijuana, but we have a prescription drug problem in this country. you can watch the front page. >> so all of those two go together. >> they're not separate. we have a prescription drug problem in the country. >> all right, real quick, medical. >> here is what they're missing. it is called epigenetics. each generation that smokes pots with animals gets fatter, less brain cells, you can end up generation after generation. it is a behavior. when you're a bad boy and you eat junk food you don't get fat in a day. the reasoning that is here is blinded and shallow and nonmedical. you -- just because you smoke pot once and you get away it and smoke pot in a year and get away with it means nothing. long-term usage. >> long-term. >> all right -- >> sean, you have to have some political reasoning here. just like slavery destroyed a country in terms of its freedom, just like in new york, new york city voted for mclellan. you talk about

ammunition, his reported mental health issues, and the medications he was prescribed like the sedative ambien. on capitol hill, army officials told congress that while lopez, an iraq war veteran, had a spotless service record, he also appeared to have an unstable psychiatric condition. >> he was seen just last month by a psychiatrist. he was fully examined. and as of this morning we had no indication on the record of that examination that there was any sign of likely violence. >> reporter: sources tell cnn police searched the apartment where lopez has recently moved with his wife and young daughter but have found no evidence such as a suicide note to explain the shooting. >> and pamela brown with us again. pamela, today for the first time we heard from lopez's family. what are they saying? >> reporter: that's right. lopez's father breaking his silence for the first time in a statement, john. he said he is astonished, he is saddened by what happened, and said "my son must have not been in the right mind. he was not like that". he also talked about his son's medical treatment for his mental hea

we know that he had multiple prescription medications, including ambien. this will be just the beginning of the medical history that they will look at because the question on the table will be, did military mental health care potentially, possibly miss some sign that this man was headed for such trouble? we know that he bought a weapon on march 1st. we don't know the last time that he saw a military health care provider but that health care provider, if they knew he had a weapon, did they miss some signs? did they miss any indications that this might be about to happen? this is going to be just one area of the investigation. >> he had a four-month tour of duty in iraq. four months. usually for soldiers it's at least a year. often it was 15 months when the u.s. deployed tens and thousands of troops in iraq. that raised some red flogs, in my mind, and i know that you've been looking into this. were there any signs of mental instability then? >> well, we don't know if he had mental issues that far back but he did serve -- you're right, the last four months of

. >> reporter: lopez had been described powerful antidepressants and sleep drug ambien. he was getting help. >> he was seen just last month by a psychiatrist. he was fully examined. and as of this morning we had no indication on the record of that examination that there was any sign of likely violence either to himself or to others. no suicidal. >> reporter: major hassan killed 14 people here in 2009. mental health issues, he says, must be aggressively treated, particularly when antidepressants are given. >> you have to be very cautious and take care to be aware of which symptoms are improving more quickly than others. people's motivation comes back and their ability to sleep comes back and they feel more energy, but still feeling hopeless and suicidal. >> reporter: now the other thing we learned that mr. lopez purchased his gun legally in a store called guns galore and the same store where nidal hassan perched his gun for the killings here in 2009 and another man bought gun powder and ammunition there, but never got to carry out a plan. he was trying to copy cat that of

there was arguments and some evidence he was on ambien. at the end of the day, this isn't just a military problem. this is our country set these men and women in harm's way. it's our responsibility collectively to answer it. i do want to say congressman carter is absolutely right. the va funding is gone before president obama got in there, just under $100 billion a year now it's about $150 billion a year so, basically a 50% increase, which is tremendous. i should say $100 billion. but it takes more than that, alex. it takes all of us coming together and making sure we're aggressive about this. >> congressman murphy, to go back to the events of yesterday for a moment, there are many persons of interests here but one of the people i think we'll be discussing more in the coming weeks and days is the female military police officer who apparently engaged in small arms fire with the presumed shooter. she was apparently not wounded. sounds like she is one of the heroes, probably one of many heroes we have not heard about but she is one of the maj
