NASHVILLE, Tenn. (WKRN) – Nashville firefighters are working to determine what caused a home south of downtown Nashville to go up in flames early Monday morning.

Fire crews were dispatched to a structure fire call at the intersection of Wharf Avenue and Timble Street just after 5 a.m. to a house that was engulfed in flames.

The Nashville Fire Department’s chief told a News 2 crew on scene that it appeared the house was vacant and had large equipment outside the residence preparing for demolition.

After the fire was extinguished, a neighbor informed fire personnel that they heard someone screaming from inside the residence.

Fire investigators took over the scene to conduct a full search of the residence and concluded no one was inside.

The cause of the fire remains under investigation.
