Luxury Mexican hotel suspends operations after deaths of American couple.

A luxury hotel in Mexico owned by Hyatt has temporarily suspended normal operations following the deaths of a California couple due to "intoxication by an undetermined substance." The hotel will not resume normal operations until the investigation is complete. The couple had been treated for what they thought was food poisoning days before their deaths. The sibling paramedics who responded to the incident are now receiving medical care at a private hospital and have medical bills, according to a fundraiser for the pair.
