Two Americans who were on vacation in Mexico were found dead in their hotel room on Tuesday, 13 June after apparently being “poisoned” by an unknown substance. The couple, identified as 28-year-old Abby Lutz and 41-year-old John Heathco were staying at the luxury hotel Rancho Pescadero in Baja California Sur. Paramedics were called to the couple’s hotel room after receiving a report that they were unconscious, according to ABC News. However, once paramedics checked they determined Lutz and Heathco were unresponsive and did not have vital signs. Now, Lutz’s family is speaking out, believing the two suffered from carbon monoxide poisoning. Here’s everything we know so far. What happened Lutz and Heathco were on vacation together in Baja California Sur, according to a statement in a GoFundMe started by one of Lutz’s family members. The two were staying at the Rancho Pescadero, a luxury hotel and Hyatt property located in El Pescader, approximately 40 miles north of Cabo San Lucas. Lutz and Heathco began to experience symptoms they thought were consistent with food poisoning and went to the hospital for treatment during the trip, according to Lutz’s GoFundMe. The couple started feeling “much better” several days later. However, their families received a phone call later saying Lutz and her boyfriend had “passed away peacefully” in their hotel room in their sleep. Paramedics in the area responded to a report of two unconscious people in the hotel and arrived around 9pm on Tuesday 13 June. The Baja California Sur attorney general’s office said in a statement that the two died of poisoning by an unknown substance and had no signs of physical violence. They said the two had been dead between 10 and 11 hours by the time they arrived. Lutz’s family said they were told the deaths were “due to improper venting of the resort and could be carbon monoxide poisoning”. Henar Gil, the general manager of Rancho Pescadero said in a statement provided to The Independent: “We are truly heartbroken by this terrible tragedy. Our hearts are with the impacted families and loved ones during this unimaginable loss.” “Local authorities are still actively investigating the situation, and the safety and security of our guests and colleagues remains a top priority, as always. We can confirm there was no evidence of violence related to this situation, and we are not aware of any threat to guests’ safety or wellbeing,” Ms Gil said. She added “We are working to care for those who have been impacted and we are working closely with authorities as they conduct their investigation to understand the cause of death. Further inquiries should be directed to local authorities.” Who are the victims? The victims are Abby Lutz and John Heathco. According to the GoFundMe description, they were dating at the time of their deaths. Lutz, 28, was from Newport Beach, California but grew up in Idaho, her aunt, Karen Lutz, told The Daily Beast. According to Karen, Lutz loved travelling and had previously visited Europe, Asia and Mexico. “Abby was supposed to meet up with her dad this week for Father’s Day,” the GoFundMe description for Lutz says. “Abby was the most beautiful soul and we will miss her so much.” Her family is asking for assistance in bringing her home so they give her a funeral. Heathco owned a health supplement company in Newport Beach, according to his LinkedIn profile. It is unclear where he is from originally.
