ARDMORE, OK - Ardmore firefighters are investigating what caused a vacant home to go up in flames early Wednesday morning.

Firefighters responded to the fire on the 1200 block of Mary Niblack Rd. around 5 a.m.

Ardmore Fire Marshal Cylde Ellis said since the home is vacant, the structure had been burning for a while before a call came in about the fire.

Ellis said the listed home owner passed away some time ago so they aren't sure who's currently responsible for the property.

The structure is a total loss.

Ellis said they are also investigating another house fire in Ardmore that happened Saturday.

No one was injured in either fire.
