Investigators are calling an early morning house fire in Crawford County suspicious.

The first calls for a fire came in around 3 a.m. Wednesday, at 622 West Central Ave. in Titusville.

It's a vacant home, just west of the Moose Lodge parking lot.

Crews at the scene say it looks like the fire started in the back of the home, and extended to the second floor.

There was no power in the home at the time of the fire, so a State Fire Marshal is being called in to investigate.

They say they'll be checking cameras from nearby businesses.

Parts of Route 27 remain closed.
