Three men died and two more were taken to the hospital after the travel trailer they were staying in filled with carbon dioxide overnight while they attended a three-day country music festival in southern Michigan, CNN reports.
A friend of the men’s called authorities after he hadn’t seen them during the final day of the Faster Horses Festival in Lenawee County. Medical crews found three dead and worked to revive two of the men, who were transported to a local hospital in critical condition.
The county sheriff’s office believes the source of the carbon monoxide was a portable generator located too close to the travel trailer. “First responders stress the importance of keeping generators away from camping areas, tents, travel trailers, etc. as well as exhaust fumes from running vehicles,” police said.
