Everyone inside the home made it out before it became fully engulfed in flames. Deputies spoke to the residents, and learned that the fire started after a fight broke out between two people who did not live there.

The homeowners told detectives that they hired a mechanic to fix one of their vehicles, and allowed him to stay there for a few days. This morning, the mechanic's girlfriend came to the house and started banging on the windows.

He told deputies she was upset about him staying there, and she threatened to burn down the garage.
