A man was found dead in his home Thursday morning after a tornado tore through overnight, according to the fire chief in Rock Ridge, North Carolina.
"The tornado had completely leveled the house. ... We were initially unable to locate the victim," Fire Chief Walt Williamson said. "We called in the FEMA rescue team, which brought in a canine unit to help us find and locate the individual."
"The victim was likely asleep in his bedroom when the tornado struck," Williamson said.
"This was an incredibly challenging task, both logistically and emotionally. It's a lot of destruction to witness," he said.
The tornado also caused major damage to a school in the area, Williamson said.
"The school's roof was torn off," Williamson said. "Thankfully, this happened in the middle of the night when no one was there. If it had been during school hours, it could have been much worse."
