Two families were displaced by an early Wednesday morning fire in Killeen.

A Killeen Fire Department spokesman says the alarm was turned in shortly after 2:30 a.m. by a neighbor for the fire in a duplex at 3207 Baldwin Loop.

Smoke and flames were seen coming from the roof of the “A” side of the duplex by firefighters as the first units arrived.

A Fire Marshal says the inside of the ” A “side was gutted, with fire entering the attic and burning through the roof.

Two adults and four children who lived in the unit were out of town at the time, but neighbors in the “B” side were home and got out safely.

While the fire was confined to the “A” side, the “B” side suffered heavy water and some smoke damage and both families were displaced.

Fire investigators say the exact point of origin for the fire was impossible to determine and the cause is under investigation.

The last firefighter left the scene at 8:30 a.m.
