Overview

• Toxicology tests revealed a carboxyhemoglobin saturation of 64% in Miller Gardner's blood, far exceeding the lethal threshold of 50%.
• Authorities identified a machine room adjacent to the family's hotel room as the probable source of carbon monoxide contamination.
• The Arenas Del Mar Beachfront & Rainforest Resort denies lethal gas levels in the guest room, attributing contamination to the machine room only.
• Initial theories of food poisoning and asphyxiation were ruled out following autopsy and toxicology findings.
• The investigation, supported by the FBI, continues as the Gardner family requests privacy and encourages donations to the Make-A-Wish Foundation in Miller's memory.
