PRINCETON (CBS) — Lightning may have started a fire that damaged a Princeton home, said Fire Chief John Bennet.

Officials say the homeowners heard the storm around 3 a.m. Tuesday morning. A few hours later when a woman went downstairs to calm their dogs, she discovered the fire.

Crews were having a difficult time fighting the fire because there was not a water source nearby. They estimated it would take hours before the fire is completely out.

Everyone in the home at the time of the fire made it out safely and no one had been injured, according to officials.
