All three died of respiratory failure and pulmonary edema.
overdose of fentanyl?
Is Legionnaires’ disease a possibility?
Sounds like cyanide or Ricin....
Well not ricin anyway since it takes longer for ricin to do its damage. Even flu doesn’t take you out suddenly the way this lady died. Someone poisoned her...
...All three died of respiratory failure and pulmonary edema.
I bet it’s methanol poisoning
Cyanide, maybe? It's quick, so much so that the victims might not have time to seek help, and I believe I recall reading that it's hard to detect post-mortem.
Respiratory failure and pulmonary edema are both listed as possible signs of Glyphosate Poisoning (Roundup). I wonder if some of the rooms had bug infestation problems and were sprayed with roundup. Or if something more sinister like poisoning the drinks in the mini-bar is possible?
