Overnight house fire in Limestone County

The Limestone County Sheriff's office is investigating a home that has caught fire twice within three days. The first fire started Tuesday night on Oak Crest Drive. At that time, only the garage was damaged and fire investigators ruled it suspicious. Overnight around 11pm, the same home caught fire again, and this time the house sustained quite a bit of damage.  Deputies spent much of the night searching for the homeowners. This morning the case has been handed over to investigators with the Limestone County Sheriff's office.
