Two Americans, Abby Lutz and John Heathco, were found dead in a hotel room in El Pescadero, Mexico on Tuesday. Initial forensic examination indicated intoxication by a substance, though authorities are still determining what it was. The family of Abby Lutz has set up a GoFundMe page to help return her body and cover the cost of a funeral, believing the couple may have died from carbon monoxide poisoning due to improper venting at the resort.
