According to The Daily Sentinel, an investigation is now underway into other factors that could have caused Romero’s death.
“We’re looking at all possible causes,” the Colorado Department of Labor and Employment spokeswoman Cher Haavind explained.
“This is extremely rare, which is why the investigation is taking longer.”
The indoor recreation company, Get Air, said it “feels deep sorrow and profound sympathy for (Romero’s) family and friends in their loss, and expresses its sincere condolences to them”.
“We are fully cooperating with the Grand Junction Police Department, the Occupational Health and Safety Administration and Colorado State regulatory agencies in their investigations of the incident,” the company added in a statement.
