Firefighters responded to a large house fire in Brentwood.
The fire broke out at a home in the 900 block of Elmington Court around 7:20 p.m. Thursday.
Brentwood's Fire Chief said a neighbor called police when he saw flames coming from the home.
No one was inside the home at the time, but a pet was not able to escape the flames.
It was possible the fire was due to a live Christmas tree that had its lights on inside the home, but the exact cause had not been determined.
Officials said crews were on the scene for several hours. They were there overnight battling hot spots.
The investigation into the fire remained ongoing.
