anthrax the centers for disease control has just confirmed the diagnosis of anthrax in a patient in a florida hospital that was really the day one for us. >> october >> most people knew nothing about anthrax before 2001. >> anthrax has been called the poor man's nuclear bomb. >> it is only a few microns in size and has the capability to kill millions. >> anthrax is actually the disease bacillus anthracis is the we'll call it the microbe that causes the disease. so people use them interchangeably anthrax is a spore forming bacterium, easy to make, easy to weaponize, and the ability to grow up. >> anthrax in the laboratory turn it into spores and then distribute those spores as a biological weapon. it can be devastating

nature anthrax is a very uncommon human disease in the united states grazing animal, cattle you might see a farmer in a certain situation might be exposed to that but you don't typically see people working at a, you know, like the national enquirer being exposed to anthrax anthrax comes in a lot of different disease forms there's cutaneous anthrax meaning it's infected in the skin. >> and that usually presents with a very unattractive scab and scar, usually black. the second form is gastrointestinal which would be more likely if you ingested something that was contaminated with anthrax spores. >> but inhalational anthrax is the form that's used for biological weapons because that's the most deadly form of anthrax. >> because the infection that

it creates in your lungs system is very toxic and really shuts down your ability to breathe and bob stevens was very quickly identified as a pulmonary or inhalational case. >> florida man is hospitalized, infected with anthrax, i think it was 1976. >> was the last inhalational anthrax victim seen in the u.s. i don't know if there are any doctors in the u.s. who had seen an anthrax patient investigate why where, when how the pressing issue now is determining where the anthrax came from. >> we interviewed the wife at length. for many many hours. i asked her to try to do your best. going back time, place person where he went. um, where he ate, where he played, who he was with, and give me a description. he ate all kinds of different things, and he

could have gotten it from eating goat. and he did buy goat from uh, a delicatessen down the road from where he lived during the time that mr. stevens was incubating. he was traveling up to north carolina to visit his daughter. >> he had done a hike in the woods. he drank some water out of a spring there. could he had gotten it from spring water. there had been anthrax historically in north carolina so it wouldn't be impossible. that's just really unusual. >> you can't completely rule out that thought but context is everything. and in the context of 911 and what we were looking for we had to err on the side of assuming that this represented something intentional the people who flew those planes on nine over 11 learned how to fly in our county their planes you know, to

fertilize their crops mr. robert stevens, he lived an hour from one of those airports >> the fbi issued a nationwide alert indicating the possibility of attacks using crop dusting aircraft to distribute chemical or biological weapons of mass destruction as potential threats to americans. >> and i went there and actually saw white, white powder all over the place. so it didn't take too much to put two and two together. that this could be a spot where something like this could occur. >> you're still open to the possibility of this being bioterrorism. >> we're open to we're open to the possibility of anything we contacted the people who worked at the army building one of the coworkers of mr. stevens recalled that an envelope had been received in the office a few weeks before he was ill the

letter had come in addressed to j.lo and so one of mr. stevens friends brought the letter in to show him and mr. stevens he opens the ladder up and the envelope had some powder in it and some of the powder spilled on the keyboard when we examined army building, we took a swab and you swipe it along the keyboard we put it in a little device, clicked it and sent it off, and it was positive and the minute they found that, they knew that this was a bioterrorism attack

people's noses. the nose was the sniffer of the spores. >> not only did each of the employees have to be tested, all of their children had to be tested. >> we were leaving no stone unturned. >> we didn't want people to die by tomorrow, the fbi should be done collecting samples at the building where traces of anthrax were found on a computer keyboard. >> robert stevens, who worked there, died of anthrax last week but that wasn't the end of the story because we had to figure out, well, how did it get there we traced the spores back to the mailroom arnesto blanco worked in the mailroom, sorting the mail. >> and so they tested mr. blanco, and lo and behold his nasal swab was positive. and that's how we knew within five days it was in the mail. >> i always credit doctor brad perkins, who is one of the lead cdc investigative officers, because brad, he literally

traced backwards from that mailroom throughout the postal system, the vehicles that move the mail, the local postal facility and so on and so forth. >> a very small amount of anthrax was found in a post office sorting facility in boca that served the army building. >> they didn't know what other letters could have been sent where that particular letter could also have gone. >> do you think this is some sort of thing against you and what you publish? >> i think this is an attack against america and that it could happen to anybody month before nine over 11. i was opening the mail as a desk assistant for tom brokaw. >> we received love letters. we received hate mail. it ran the

gamut. but i came across this letter that looked a bit different. i opened it, you know, it said 911, death to israel allah is great. this is really creepy. and i saw this brown substance that looked like it was a cross between brown sugar and sand. and i took the substance. i dumped it in the trash, folded up the letter put it back in the stack of mail, gave the stack of mail to tom's assistant ten days later, when i woke up and my glands were enormous, i basically had no neck and i had a really high fever and it was like a super intense flu, but in a totally different way because i had lesions all over my legs. they look like dark bug bites. i'm freaked out that time span in the next week or so is when bob stephens opened his letter

learned that tom's assistant was also ill and had been out of the office and i mentioned that there had been a letter that i came in contact with. folks started to sort of put the pieces together. >> this morning we received a positive test for cutaneous anthrax for one of our colleagues who works on nightly news. >> so i'm back at work. i just had a black lesion removed on my finger. i have this little funny looking cast on the tip of my finger and there are tv monitors playing news throughout the newsroom and the nbc case broke, and nbc nightly news employee has tested positive for a skin anthrax infection. they were going over all of the symptoms. can i just

immediately, because the assumption was that the anthrax would get into the ventilation system and contaminate others as well we had to shut down the building an extremely daunting task. we then learned other senators had been targeted including senator leahy. >> it appears that the letter sent to me may contain enough spores to kill well over 100,000 people. >> a letter like that could could hold certainly billions of spores and a billion spores could kill hundreds of thousands of people if distributed properly. >> it was pure chaos i just talked to leader daschle and his office received a letter and it had anthrax in it. >> i saw the news report about daschle's letter we knew that it had to come through our building all of the official mail mail that went to

congress, the supreme court would come through brentwood. so we knew that this possibility that we're in trouble brentwood was open 24 hours a day, that moves thousands and thousands of letters through the system on a minute by minute basis. >> and it never stopped thomas morris worked in the government mail section joseph kristi noem joseph worked directly on the machine that processed daschle's letter those letter sorting machines, the lsm 17, those rollers go like 35 miles an hour they're pressurized machines all these letters that come through here drop some particles those envelopes leaked spores and that's what happened at the brentwood postal office. the daschle letter and the leahy letter came through on the 12th, the 18th. mr. carson and mr. morris

>> it was major case 184, known as amerithrax. this became the bureau's number one crime to solve. >> to date, we have 14 confirmed cases of anthrax. >> it was immediately the priority for the office of homeland security we are aggressively to find and bring to justice those responsible for these terrorist acts. >> we were seeing threats in every shadow and over the next month and a half, we would learn of a potential smallpox attack. >> we would learn that the white house detectors had detected botulinum toxin. and as the vice president put it to the president anyone who was exposed was going to die discussion about the mail. >> what do we do about mail everywhere that these letters

went, they left a trail of anthrax. >> and those spores started going around. other letters got contaminated. some of those letters were headed out around the world. >> when do you shut down a given postal facility? those were some of the really toughest decisions, because there's a big downside to shutting down the u.s. postal system. it basically shuts down our economy. >> we used to call it a weapon of economic destruction. even though postal didn't shut down the mail system, they did some procedures that effectively slowed it down dramatically. we had truckloads tractor trailer loads full of quarantined mail on the other hand, it was tragic to lose postal workers from something that had we understood better what was happening with these envelopes, we would have been able to prevent. at this point, we've got to follow the trail back to whoever sent this and we sent the letters down to the behavioral analysis units for analysis. i think the assumption was that this was most likely foreign because of the messages that had been sent

to many, including me. it was deliberately designed the wording to make us look at the al qaeda group as the perpetrators. >> given the events of nine over 11, some assume the anthrax scare is connected to osama bin laden. but what if it's not? >> we dropped that theory because the profilers down in quantico, the behavioral analysis agents said this is all intentional. what you should be looking for is what we call lone wolf. somebody very astute scientifically, fbi behavioral analysts believe it's most likely one person sent the anthrax laced letters. >> they think it's a male individual with some scientific expertise and capacity. the person who picks his targets carefully the profilers are usually right we had to find this person making bioweapons. >> so evidence was taken to paul skenes lab. >> this high security lab is one of the only places in the world where genetic fingerprinting of anthrax

bacteria is being done. >> tokheim had an identification system for anthrax, which was his own he had invented it. >> if a person started using anthrax as a we could trace it back. >> it's a fingerprint the bacterial fingerprint. and that could really give you clues used to solve a crime. >> we started analyzing the anthrax. we started running the dna fingerprint against our database. and in all of the letter cases, it came back and lined up with this one particular type of anthrax known as the ames strain. well, we knew the ames strain. really well. we had the same strain in my laboratory. it was a strain that was widely used for experimental purposes. when you're trying to develop a vaccine, you've got to have live anthrax to do it and the ames strain was the go to strain in those days for testing your vaccines. everybody who had access to anthrax from all the different laboratories across the united states was on the potential suspect list.

imperium. but power comes with a price doom prophecy. >> streaming exclusively on max is trying to murder americans by sending anthrax in the mail. >> the ames strain, from an investigative point of view is sort of a lucky break in some ways, because it was more likely came from a laboratory. so all we had to do was find those who had access because anybody who has access is a suspect. access to ames. that was the key. i sent out subpoenas to all the laboratories that maintain anthrax. >> once we figured out where the ames strain was, then what they did was they subpoenaed the actual samples. >> so we can test it against the stuff in the envelopes. by the time we were done, we

samples of ames. by may of oh four, we had eight matches out of 1056. eight of those matched the spores in the envelopes army laboratory in frederick maryland. >> fort detrick our country started a program in the 50s to grow anthrax and produce weapons, and that was done at in frederick, maryland, at fort detrick. >> the united states abandoned its bioweapons program under the leadership of richard nixon. >> so fort detrick switched gears from biological warfare development to biological threat agent research which included developing anthrax vaccines. >> sources say a scientific examination showed the anthrax used in the 2001 attacks originated here at the fort detrick army lab in maryland. >> they all focus down on one

flask, which was the rmr 1029 flask that was being maintained by a scientist named bruce ivins for his research on anthrax vaccines. >> bruce ivins is a heroic figure in biodefense. >> bruce ivins sent this photo of himself investigating anthrax to friends and colleagues shortly after the anthrax attacks, attacks which the government genetically to a flask in ivins lab over which he had sole control bruce ivins was born and raised in lebanon ohio. >> bruce was a talented scientific mind. i think from a very early age and was recognized as such and ultimately went to the university of cincinnati for his undergraduate degree and his ph.d. he was hired at fort detrick as a microbiologist to start working with anthrax inside usamriid the united states army medical research

institute for infectious diseases to help put the united states in a better position to defeat a bioterrorism attack on the surface, bruce ivins was a sort of a bubbling personality known as a sort of eccentric sort and in the environment up there at fort detrick. i mean, that kind of personality was a welcomed because they're dealing with, you know, pretty serious stuff. >> i've been working with bruce since 1998. bruce was very smart, a very smart guy but had a number of little quirks. >> bruce had been called in for more than one interview. he was anxious to help identify especially people he didn't like as the mailer i was an addictions counselor. >> bruce ivins, he was in the group. he blamed literally every single one of his other coworkers for the attack.

>> he would say, well, yeah, i'm the foremost expert on anthrax. >> and i could see why they thought it, you know, might be me. >> and but it's not it isn't me it isn't me. >> ivins is not the only person who works at usamriid, so you have to eliminate people. you have to look at even their access to the lab. each laboratory had a magnetic reader so you card in and you card out in the security office kept those records right before each of the two mailings that we knew about ivins had changed his pattern of working in the laboratory. and before each mailing, he had spent a lot of time in the middle of the night inside those laboratories. he had never done that before. so then the agents went in to interrogate him further and we began to see that. >> yeah, this, this image that we had of him was only a surface level thing. in fact bruce did have a dark side

for years. >> he had a fixation with kappa kappa gamma, a woman's sorority when he was in grad school. he was turned down for a date by one of the kappa kappa gamma sisters. he hated that sorority. when he was interviewed, he admitted burglarizing several kappa kappa gamma sorority houses. he goes, it's not an interest. it's an obsession. he admitted it. it all started to point to him as the strong candidate. >> and of course, he is the one who we know that created rmr 1029. there was no one who had greater access to it, greater unfettered access to it than bruce ivins. >> they think it's him he was starting to definitely realize that we were looking at him now. >> he was so paranoid at that point. >> he thought my office was bugged. >> he thought the group room was bugged.

>> he thought the telephones were bugged. >> he was just so worried that the whole world was out to get him he was having difficulties at home and difficulties at work drinking heavily and taking medication. and he was unraveling. i was sitting in my office and the receptionist came running into my office and she said, something's really wrong with doctor ivins tirade and he had this look on his face. that was something i'd never seen. and he just went on this rant about the fbi and how everybody wronged him and he started talking about roaming the streets of frederick, trying to find somebody to hurt. and everybody was just silent and and then he started going off about the fbi was about to indict him on capital murder and he wasn't

going down he was going to go out in a blaze of glory. he talked about having weapons. he said he was going to go to work the next day and take everybody out. i knew we had to report it. so i called the police she realized that she was under obligation to report this to the authorities patient therapist privilege no longer held because he had explicitly made death threats. i know if i hadn't made that phone call other people would have died. >> his whole life was kind of coming down all at once, and that was kind of the beginning of the end developments tonight in the investigation into the deadly anthrax attack seven years ago. >> the main suspect in the case, army scientist bruce ivins, committed suicide bruce committed suicide as the fbi

was moving in on him. >> he took a lot of secrets with him. >> i don't think we know it conclusively, but what we believe now is that the person who mailed these anthrax weapons was convinced that people were ignoring the real threat that bioterror can present. and so his attitude was, i'll prove to them how much fear and concern and threat that it really is during the summer of, oh one, the pentagon began to wind down on the anthrax research. at that point. >> what can he do to to undo that? you create a shock and awe bioterrorism event. >> if the goal was to get the government to think about the risk and how much to invest, and that was achieved. >> billions and billions of dollars of money went into this area. >> so maybe that was the cause. but we'll never know. biggest investigation in the fbi's history probably not to go to

court and to be able to show the public that we did solve it. we found out who did it and here he or she is is very unrewarding. and as a detective, you do feel cheated the bad guy wants his day in court. his or her day in court. so do we. >> so 22 people were known to have been infected with disease related to this series of letters. five of those people died but everyone was affected everyone in the country was frightened all the horror of those times. >> i think my brain doesn't want to go there. i still don't know what to make of it brentwood was the place where we went and we laughed and we joked. >> it was like family, you know i've never stepped foot back in that building. there are a lot of people who have not i

mean, i have ptsd still in many ways, you know tears and anxiety and, you know frustration it never happens again years after the anthrax attacks, the fbi closed the case. >> they named doctor bruce ivins as solely responsible for the letters that killed five people, including a 61 year old new york city hospital employee and a 94 year old widow. in connecticut. 17 more people were included in the government's list of victims, but a later study asserted that dozens more were affected by incidental infection. since the attacks, the brentwood mail facility has been renamed the kursk region maurice mail processing and distribution center in honor of the two postal workers who died. i'm jesse l martin. thanks for
