She was in a lot of pain. Excruciating pain. Spirit like a zombie. I knew she was gone. What was happening to this young mom . Someone said, could this be a poison . This was the stuff used by russian kgb agents. Who would even think of this . Need to search the computers and phones. This was done on purpose. This evil came into our lives. How can this be . Welcome to dateline. Brigida uto love to run and was hardwired to go the extra mile in everything she did. Then, suddenly, her health collapse. Doctors were baffled as her symptoms multiplied and grew more alarming. Then, this Kind Pending Mystery took a sinister turn. Someone wanted her dead and thought they hatched a foolproof plan. Could a physician and the fbi stop it in time . Here is natalie with the Prussian Blue mystery. From the moment the ambulance arrived at the san diego Emergency Room in march 2018, the situation was frightening. And desperate. Triage nurse Laura Comstock took one look at the young woman on the gurney and knew something was terribly, terribly wrong. She was losing her vision. She couldnt feel her extremities her hands. She could not see the water i was giving her. The patients name was brigida uto. She had just turned 28 yet she seemed to near death. At that point, she was very sick. Probably the sickest patient in the er at that time. I told my coworker she my code on me. Whatever was Killing Brigida was not evident. There were no bruises. No wounds. No obvious signs of infection. And yet, when the doctor examined her she was critically ill. So began an unusual detective story. The doctors had to unravel a medical mystery. Soon enough, real detectives would be on the case too. At that moment. We saw someone almost did not have a personality. She could barely talk or tell us anything. Looking for clues, the doctor dove into her medical records. They were extensive. Brigida had been suffering for months. Nausea, fatigue. She had been in and out of Doctors Office and ers repeatedly. Her sister said that illness would come on suddenly. She was violently sick. Had to call out from work. Sick for days. Various doctors came up with their is from fibroids to cancer. There was one doctor who told her that, you have really bad menstrual cramps. She felt one of her symptoms that her ovaries were about to fall out of her body. She called me and told me this and she was crying. She said, i dont know what to do. I am frustrated because no one can tell us what is wrong with her. She had wondered if stress could be making her sick. She had a toddler to chase around. A husband in the navy trying to find a new career. A new job teaching special ed. It was thrilling but overwhelming. Doctors put her on medication for depression. Then, she got sick again. She kept going to the doctors, and she kept feeling worse and worse and worse. She started losing a lot of weight. Her mom felt helpless as her daughters illness progress. Were you getting more worried seeing your daughter waste away . Yes. She was tired of going to the doctors and them finding nothing. She says, mom, i give up. Im not going to doctors anymore. I said no, you cant. You have to go back. You cannot give up. She was not even walking normally anymore. When it seemed things could not get worse, a disturbing new symptom. I went to see her. She her Kitchen Floor and she was crying to me. She said she pulled out a chunk of her hair. Just in the shower. It came out. Brigidas Beautiful Lock started falling out by the fistful. When you see her lose her hair, you think that was her most beautiful trade . How concerned were you . We were beautiful can we were very concerned. She said, mom, i need to go to the hospital. She said i can hardly breathe. She lived in a house next to her parents, and yet that morning, she couldnt see her way to their place. The pain in her legs so bad she could barely get into her mothers suv. I tried to help her by raising her like, but even the touch was painful. She screamed. Her mom raced her to the naval hospital. She said drop me off his clothes as you can to the entrance. [ crying ] i still remember i saw her walking. She walked like, you know, the walking dead. Like a zombie . Like a zombie. The navy doctors could not figure out what was wrong. Her husband took her back to the Family Doctor who called an ambulance when he saw how sick she was. At Kaiser Hospital she was a Doctor Mystery Painton patient. He saw her and said its not right. From there the team was called. The doctor has Board Certification in medical toxicology. A rare thing in an er. As it happened, his expertise would prove critical. I am a little more of a detective role. What was causing brigida s here to follow not to mention the severe pain, vision loss, and weakness . The doctor said it could be lupus. She had this chronic, with the ring slow course. Autoimmune stuff was on the list. Cancer does not make you lose your hair. Its the chemo. The doctor knew we had to solve the mystery fast. Brigida was fading. The clock was ticking. When i saw her and knew she was dying, she was in excruciating pain. I remember being in the Hospital Room and she was like, i want to be close to my sister. She put herself through and insane amount of pain to turn her body so she could look at me. How close was she to dying . Iwatch my sister almost die. I knew she was gone. A familys anguish deepens and the race to unravel this mystery shifts into overdrive. Coming up. Your daughter is getting weaker. She was losing her vision. She was losing everything.

Natalie morales here at Kaiser Permanente hospital in san diego, brigida uto was so weak she couldnt even conjure up the energy to care about what here at Kaiser Permanente hospital in san diego, brigida uto was so weak that she could not conjure up the energy to care about what was happening to her. Doctors have a term for patients in this apathetic state. You have lost your hair and you cannot walk and you are wasting away. You are so sick to have the insight to say im really sick. That tells you she was as sick as she could get and possibly was near death . I think so. Dr. Lapoint did not know what was making brigida sick, but to his toxicologist mind, her symptoms indicated she might have been exposed to a toxic chemical. He realized she might not be the only one. There are so many moving pieces. Theres a child in the equation and a spouse. Lets make sure we are observing them. Make sure the child the safe and they have not been exposed. He had her husband and son admitted to a separate hospital for testing and for safety sake, he banned all visitors from brigidas Hospital Room. Even immediate family. There was a time you did not know what was happening to your sister. Did you think this might be yet . She might be gone already and they are not telling us . I was like a zombie. Going through the motions. Hoping she is okay. Knowing if they had not call me to tell me shes gone, its because she is still here. Olga is two years younger and they had always been close. We shared a bedroom when we were little. Every night was like a sleepover. We did everything together. We were literally there for everything that happened. Through our childhood, teenage years, delay. She was my go to person. Their dad worked for u. S. Customs at the border. They had grown up in rural san diego county. Its a safe, idyllic upbringing for your daughters . Everyplace has dangers. Over the years, we had a rattlesnake here or there or somebody came through and stole a pickup truck. There is danger but that goes with anywhere. You cant protect them from everything. From their dad, they learned caution. From their mom, they learned the importance of faith. I put them in catholic school. They teach moral values and things important to life. Brigida would beg to go to church during the week . Yes. The little girl who beg to go to church grew into an accomplished young woman who ran crosscountry and excelled in school. Did she put pressure on herself to be perfect . She has always been that way. Evening kindergarten, they would get a lot of homework. If she made a mistake, she didnt want it to show she had he raised something. She would start all over. Near the end of her senior year in high school, she met a young man named race uto. A runner like she was. A great behind her but ambitious and determined to go to the naval academy. When did you first hear about race . I was 16 years old. She met him at a car show. She was doing it for the graduating class. He did not go to our high school, but he was there. I remember her saying, i met this guy. I said, okay. I didnt think much of it because my sister did not take that much. As olga got to know him better, she thought race maybe the guy brigida needed. She was always into her books. She stuck to the rules. He took her to the adventurous part of her life. Kind of got her out of her shell . I saw a different side of her when she was with him. Race made it to the naval academy, but he suffered a hernia that never healed properly, and eventually, he had to withdraw without graduating. He did join the navy. In 2014, brigida and race married and very soon, she was pregnant with her son. Everyone was thrilled when the baby came. We were all excited. We had a little doll. I would hold my nephew. We would take turns. I would take care of him when she was sleeping. Watching her learn and experience being a mom for the first time as she wanted to be, it was beautiful. Then, just before her son turned two, brigida got sick. Soon, she could barely pick up her child. Your daughter is getting weaker and weaker . And she can barely walk . She was losing her vision . She was losing everything. In the hospital, toxicologist dr. Lapoint developed a chilling suspicion about what was wrong with brigida. Do you think . Oh, my god. Coming up.

Jeff lapoint was keeping his mind open, letting the clues lead him to a theory about what like any good detective, dr. Lapoint was keeping his mind open. Letting the clues lead him to a theory about what might be Killing Brigida. Ive got to figure out whats wrong and get the treatment started. The symptoms couldve been caused by range of toxic chemicals like arsenic, cadmium. But to the dr. Lapoint one particular symptom stood out. Sudden hair loss. Thats the telltale sign. Any medical toxicologist, if you have a young woman who has lost her hair and now cannot walk because her feet hurt so bad, thallium will be on the list. Its straight out of the books. Thallium is a heavy metal. Atomic number 81 on the periodic table of elements. It was discovered late 1800s and quickly began being used medically early 1900s. Its a depilatory agent. If you had lice and you wanted them to lose their hair, you would give them thallium. For decades, thallium had another use. As an ingredient in rat poisoning. It was good for that. That was in the 1970s. It is good at killing things at the end of the day. Highly toxic. You never treated anybody else for Thallium Poisoning so this was your first case in front of your eyes. Yeah. There was no quick way to confirm his suspicion. Hospitals rarely see patients with Thallium Poisoning and do not have a way to test for it. No hospital will have a drop of blood to come back, thallium. You have to send them away. Im looking at a two or three day delay. Days he knew brigida might not have. We have a scary situation where i have a test infrequently ordered that i need now. Thats a send out. It is serious and infrequently done and it is exotic. You are in a race against time. I am trying to advocate two different people. Lots of hours on the phone to get somebody, this woman will die. When we sent the test, we said how do we get the antidote . He wanted to get ready to give it to her when the results came in. It is called Prussian Blue. Youve probably seen Prussian Blue and paint. Its a pigment since the 1700s. You can see it in Vincent Van Goghs starry night. It was not until 1965 that scientist discovered Prussian Blue could be used as an antidote. It works by speeding up elimination of certain poisons such as valium. While you can buy blue paint in any art shop, Pharmaceutical GradePrussian Blue is nearly impossible to find. We started calling pharmacies around town. We called the navy. We called the local Public Health people. We got in touch with the cdc and found they are confidential Storage Sites and we found one. Prussian blue is so hard to get because its an antidote for radiation poisoning. The u. S. Government keeps it under close guard. Stockpiled in case of a nuclear attack. No one wants to give an antidote before we prover. We do not throw around pressure him blue. We have trip where set up and this patient was in san diego. We were notified immediately of a prussian order. John gill is a Special Agent with the fbi. s focus is weapons of mass destruction. A request for the antidote to Thallium Poisoning put his office on alert. The past several decades, there been instances for thallium has been used as an Assassination Weapon against former speiser dissidents. Thats what you get this call is what is happening in san diego . That is something we were concerned about in the united states. All this just as trump is days away from a trip to san diego to talk about the border wall. You triggered all kinds of alarm bells. I triggered alarm bells. Coming up. When you are seeing this. A deadly substance in brigidas system. But how . Him proceeding the kids intentional. So am i. Because im at risk for pneumococcal pneumonia. Come on.
