that have vacation there start to say, wait, i was in that hotel and i became violently illness long ago, there starts to be a lot of questions surrounding these. the state department isn't saying much right now, just that the fbi is -- has taken some samples from some of these people. they don't have the results of those yet. it's difficult to put them all together as time passes. what we do know is that there were four people who died in one of the hotel chains. there were two that died in another hotel chain. the seventh person we don't know. that is the brother of "shark tank" star barbara corcoran. in a couple of cases they were thought to be heart attacks, pulmonary edema or fluid in the lungs is another similarity. but those could be symptoms, of course, of something else happening initially. also, in three of the cases the people reported that there were problems only after they drank something out of the mini bar.
