According to the Missouri Highway Patrol, the bodies of 66-year-old Frank Wevers the third, and his 58-year-old wife Mary, died from asphyxiation from carbon monoxide poisoning.
Their bodies were found in a camper trailer near Buckhorn, Mo. on May 28. Officers found a portable generator near the trailer, which was the primary source of power. Investigators believe the exhaust from the generator filtered in to the trailer and killed the couple. Officials say the deaths were accidental.
