Reporter so you dont lose consciousness. Elizabeth is a registered nurse. Her training kicked in. There was no sign of external bleeding at that point, so that kind of freaked me out, too.

The. 9millimeter bullet had torn through his bladder and intestines. They had to place him in a druginduced coma to save his life. He was unconscious for a month. Local Law Enforcement initially assumed the shooting was a botched robbery, but Elizabeth Joyal believed otherwise. I didnt want to seem like this crazy Conspiracy Theory woman, but i knew that, you know, it was not a carjacking. It just there is just no way that it was just some random guy. It had to have been a planned attack. Reporter because nothing was stolen and the assailants had clearly been lying in wait.

He traveled with us to london to tell us what happened to an important contact of his just a few months before joyal was shot. It was a Law Enforcement officer. Worked for the equivalent of the fbi . Yeah. In anticorruption . Anticorruption is what really he was most interested in. His name was leak Litvinenko Sasha to his friends. But his interest in fighting corruption had made him a lot of enemies including in his own agency the kgb, which was renamed the fsp. Litvinenko was forced to flee russia with his wife and son and seek asylum in london where he quickly caught the attention of agents of the British Intelligence service mi6. Glen moore trainer harvey was a retired and charming mi6 analyst who was asked to befriend litvininko. The british wanted find out what he knew about his former colleagues in the russian secret services. It was of great interest for us to know who these people were. So naturally, he was debriefed to talk about any of his russian contacts that came in. Was he incredible single in. Yes he credible . Yes he was. Credible enough that mi6 began paying him a monthly salary. Trading information for money of one way for a former russian eighth to make a living in his new home in london. Suddenly in 2006 [ siren ] litvinenko, who had always been fit and healthy, got very sick. It was just incredibly strong and heavy sickness just suddenly and not stopping. Litvinenkos wife, marina watched him waste away in a matter of just days. It was awful. His hair started to be to fall out . Yes, and he started to look like cancer patient treated by chemotherapy. I knew he was going through unspeakable torment. Finally they found, in his blood. He might be have uh, be poisoned. Reporter poisoned. Doctors suspected maybe hed injected thallium, commonly found in rat poison, and treatable with an antidote. Finally. Finally, we know what happened to sasha. And now we all under control and he will be safe. Reporter but it wasnt under control. The antidote didnt work. Litenvenko didnt get better. He got worse. Before long, even close friends, like andrei nerasov, who directed a documentary about litvinenko, which included this rare footage, could barely recognize him. At some point, i said to myself, why should this be happening to this young, healthy handsome athletic man . Whats going on . Hes fighting for his life. Reporter a fight litvinvenko would lose. Were sorry to announce that Alexander Litvinenko died at University College hospital at 9 21 on the 23rd of november, 2006. Reporter but in the days just before his death, litvinenko did something remarkable. He knew he was dying and decided to help Scotland Yard detectives solve his murder. He gave them a series of deathbed interviews. The transcripts provide a remarkably detailed account of his movements on the day he was poisoned. Litvinenkos account starts at 10 00 a. M. When he received a phone call from an italian contact, mario scaramella, whod just arrived in london and insisted he needed to meet litvinenko immediately. He said he had urgent news. They agreed to meet that afternoon. At 12 29, litvinenko caught this bus to the East Finchley station. From there, he caught a subway to central london. This is the statue of eros in piccadilly circus. Its a london landmark and this is where litvinenko met scaramella. Litvinenko liked to meet all of his contacts here. Its a wide open area with many entrances and exits and he would sit back and watch to see if people were being followed. Reporter at 3 10 p. M. , litvinenko and scaramella were spotted on a Security Camera walking west on piccadilly street. They came to this sushi restaurant where litvinenko ate lunch. Scaramella said he wasnt hungry. Litvinenko and scaramella parted ways after lunch. At 3 48 p. M. , litvinenko was caught on another Security Camera talking on his cell phone. Litvinenko then walked about a mile to the millennium hotel, which is literally right across the street from the u. S. Embassy. Its that modern looking building over there. This is one of the most secure neighborhoods in all of london. Reporter one of the hotels Security Cameras recorded litvinenko arriving in the lobby at 3 59 p. M. He was there to meet Andrei Lugovoy, another former fsb agent, seen here wearing a black leather jacket. Lugovoy had his own Security Consulting firm. He and litvinenko had been talking about doing some business together in london. The two had met several times over the past year. This time lugovoy brought along a buddy, a man named dimitry kovtun. Hes the one in the black turtleneck. It was a quick meeting. Litvinenko drank just half a cup of tea then left. Around 5 00 p. M. , he caught a ride home. That night, he fell ill. And three weeks later, he was dead. So, who so slipped litvinenko poison that day, putting his murder into motion . Litvinenko told Scotland Yard detectives before he died he didnt know when or who had poisoned him. But he had no doubt that one or more of the men he met that day. The two russians or the italian was his killer. Naturally, we wanted to talk to all three. Coming up we track down the first suspect named. Are you frightened for alexander litvenenko, the former russian agent, the man friends called sasha, died without knowing what killed him. The results from a battery of tests came in too late. But they did come in. It turned out he was killed by something far more lethal than common rat poison. Its polonium reporter polonium 210 to be exact, a rare and deadly radioactive isotope. The news shocked the world, even though most people werent exactly sure what polonium was. But paul joyal knew what it was and what it could do. That his friend effectively burned to death from radioactivity. Its a horrible death. Its a gruesome death. He lived longer than he than any man normally would under those circumstances. And he lived just long enough, within 12 hours long enough, for them to finally determine that it was polonium versus something else. Why if he had died 12 hours earlier, would it have made any difference . Because they wouldnt have found out. They would have marked the death certificate as death unknown. He would have been put in the ground and it would have been just a mystery. Unknown unknown assailants. Turn the page, move on. Its the key of this murder. Polonium 210 was discovered and now we exactly sasha was killed by polonium 210. Reporter its an almost perfect murder weapon. Polonium has no smell, little taste, and without specialized equipment, its undetectable. If you not looking particularly for polonium, you not able to discover it. Do you know . It will be everywhere, but you dont know this. Reporter the amount that killed litvinenko, slipped into something he ate or drank, was no larger than a grain of salt. But thats still a thousand times the lethal dose. And that tiny bit of polonium would have been enormously expensive. Eight to 12 million to be able to get the portion that went into him. Reporter but who could get a hold of such an expensive and exotic weapon . And just how did they deliver the fatal dose . When detectives went step by step with litvinenko through the day he was poisoned, he named three potential suspects the two russians and the italian. The first one we found was the italian. So now in rome were on our way to see mario scaramella, who hopefully can shed some more light on who killed Alexander Litvinenko and why. Scaramella has been a hard man to pin down. First, he wanted to meet us in naples, then new york, then london. He finally agreed on rome and were about to find out why hes been so skittish. [ speaking italian ] reporter how to describe scaramella . Hes a lawyer, an academic, a security analyst and also someone litvinenko never completely trusted. Scaramella, youll remember, is the contact litvinenko met at the sushi bar on the day he was poisoned. Litvinenko thought you poisoned him . Yes. You didnt poison him . Absolutely not. From his perspective, it does make sense. Uhhuh. No, sure, everything is very strange. Reporter scaramella had been working for the Italian Government and sometimes used litvineko as a source for an investigation into russian mob and spy rings. So, he was giving you names of russian mafia members yes, names, dates. Who were connected to the Intelligence Service . Exactly. Reporter something that was sure to upset both the mobsters and the fsb. Scaramella told us that in october 2006, the month before litvinenko was poisoned, he began receiving frightening emails. The final message arrived on the very day of his last meeting with litvinenko. And what did that message say . Look there are people ready to kill you. The emails amounted to a hit list. The next name up alexander. Alexander as in litvinenko. Scaramella says thats why he met with litvinenko in london, to tell him about the hit list, to warn him. But, he says, litvinenko didnt buy it. He said, mario, dont care about that. He says, its b. S. . I think its just a provocation, but please check whats happening. But after what happened to litvinenko, scaramella says he takes the hit list seriously. Are you frightened for your life . Well do you have another question . Scotland yard questioned scaramella and eventually cleared him. Why . Because if youre looking for it, polonium is traceable. Using specialized equipment, investigators were able to track it in people and places. Once polonium 210 had been identified, then across europe, like the slime from a slug all the way across, polonium was popping up everywhere. Reporter but not in scaramella. No polonium in his body or anywhere hed been. So, Scotland Yard took a hard look at the two russians, lugovoy and kovtun. When detectives retraced their steps, they found polonium contamination everywhere. We see the same fingerprints of the polonium in multiple places where they were. Reporter business offices, hotels, a hookah bar, a strip club, a soccer stadium. And the Millennium Hotels pine bar where they last met litvinenko . Thats were investigators hit the jackpot. These 3d graphics, put together by Scotland Yard, show the entire pine bar was contaminated with polonium, with extreme hot spots on a table and chair. And the levels found inside this teapot . Off the charts. Paul joyal wonders how many people were unwittingly exposed. Do we know, ultimately, what the final cost of this use of polonium is . Someone who was washing dishes in the pine bar or in a hotel, cleaning crew, do we know, ultimately . Reporter five months after litvinenkos death, Scotland Yard issued an arrest warrant for lugovoy. Kovtuns would come later. The two responded with a press conference in moscow stating their innocence. [ speaking russian ] reporter russia refuses to extradite them, so we travelled to moscow to find the men who are now officially wanted in connection with litvinenkos murder. Coming up the stakes get even higher as we confront a cop russian official. He had been speaking out aggressively against russian officials for years. How is it that all of this evidence doesnt point to russia . children laughing hes so cute what should we name him . gasps can we keep him . Please . Mom, can we keep him . Ahh both pleaaaase .
