FLORENCE, Ky. -- From Firehouse.com

Fire crews spent much of Sunday afternoon examining a home heavily damaged by a gas explosion.

Firefighters said they were called about 3:25 p.m., when an explosion reported at the vacant home near the intersection of Dixie Highway and Main Street.

Commanders said the leak was blowing into a nearby doctor's office when firefighters arrived, and both buildings sustained serious damage.

"The first suspicion is going to be natural gas. There's a natural gas leak somewhere in the building. What caused the leak, why the building exploded -- at this time those are the things we need to investigate," said Florence Fire Chief Marc Mumech.
