Gas leak and 'undetermined substance' suspected in deaths of 2 Americans at Mexican resort.

Current and former employees at a luxury hotel in Mexico where two Americans were found dead this week said managers of the resort ignored repeated signs of a possible gas leak and disabled carbon monoxide detectors to stop their alarms from disturbing guests. The bodies of John Heathco and Abby Lutz, both of California, were discovered Tuesday night inside their room at Rancho Pescadero, which reopened after extensive renovations about a year ago in the beach community of El Pescadero, an hour north of Cabo San Lucas. Autopsies suggest the two died of “intoxication by an undetermined substance,” prosecutors in Mexico’s Baja California Sur state told the Associated Press.
