Listen: Dominican authorities say tourist died of heart attack
"Authorities in the Dominican Republic have released preliminary autopsy results in three cases involving American tourists. Who died at the very same resort within five days of each other. They find that one woman suffered a heart attack a couple each had internal bleeding as well as fluid in their lungs. Final cause of death for all three is yet to be determined all of which is of great interest to a Colorado couple who say that they stayed at the very same resort last year. And believe they were also poisoned. Here's C senior investigative correspondent drew Griffin. Calin canot reached out to CNN almost immediately after learning three Americans just died at the same resort in the Dominican Republic where she believes she was poisoned, along with her boyfriend. What is your reaction blood boiling, too coincidental with the symptoms that we had for me to even begin to stay quiet about it one year ago, this month the Colorado couple traveled to the all inclusive grand Bahia Principe resort? Lau Ramana and for the first few days, it seemed a vacation of a lifetime, but on the six day canot became ill. I woke up with a headache, one morning, we had gone to breakfast to see if I could get some water get some Jews try some food feel better. And then when we came back to the room actually hit us a lot, stronger, and we the smell of chemicals, she got progressively worse than her boyfriend. Tom Schwaiger started feeling it too. They say they. Sweating, drooling dizzy nauseous. It wouldn't go away. Neither would the smell in their hotel room, we thought housekeeper outside and like called her into sif. She could come in. She walked me, five six feet into the room and turned around and said, I'm not doing that. And then got on her walkie talkie to the front desk, and said something's going on with this room. She refused to come in and clean it. Kaelin and Tom had seen someone spring plants near the air conditioner outside their room. They assumed it was pesticide, but the hotel will say what it was. They switched rooms twice. It didn't help progress over the rest of our trip. And then over the course of a couple of weeks after a couple of weeks. Yeah. The domino all the domino cramping and GIF said lasted for a few weeks. And you said, drooling, drooling wet bad sweat, tearing, dizzy, dizzy, nauseous, and the domino cramping was the worst. I was the hardest something to deal. There's so much pain back in Colorado, connotes, physician diagnosed her with organo-phosphate poisoning, sh- wanders. Doctors suspect, the same thing heavily regulated and in some cases banned in the US organo-phosphates are manmade chemicals, found insecticides exposure can cause increased saliva tear production, diarrhea, nausea. Sweating confusion and death. The couple says they still have occasional symptoms and they are most concerned about their future health even after filing a lawsuit. They still do not know what exactly poisoned them all I wanted was the chemical name that is all everyone that I could care less about the money. If I can save me on life later and him to it's, it's what happened to him. What happened to me? What, what is it that we can do at this point? And drew Griffin joins us. Now, drew you've been investigating this has a company confirmed any of this. What's their response? Their response is really no response. They have failed to answer just about all of our questions, Jim, and they will not speak specifically about this case with this couple because there's litigation involved. In the meantime, the company is chastising us, basically to not even speculate on the current death investigations happening at this same resort while those investigations continue. So we're not getting much at all from Bahia resorts"
