Firefighters in Bell County were kept busy Sunday battling house fires.

First, a father and son were without a home after their house caught on fire in Holland. The fire happened at the intersection of Landfill and Mills Roads.

Nobody was home when the fire started and the cause remains under investigation.

However, when Channel Six spoke with Bell County Fire Marshal Steve Casey, he said something is not adding up and he will likely have to bring an arson dog to the scene Monday.

A next door neighbor said she was leaving her house when she saw a thick cloud of smoke. She described the situation as “heartbreaking.”

“It's a sad thing because the house is pretty much destroyed. So, you know their contents are destroyed,” she said. “Him and his son's so it is especially this time of year is heartbreaking to see something like that happen.”

Casey said the man and his son will stay with family.

The investigation will resume Monday.

Later on around 4:30 p.m., Harker Heights firefighters were dispatched to the 2300 block of Creek Drive regarding a structure fire.

Firefighters found extensive damage to the master bedroom and smoke damage throughout the home. Two people and their pet reportedly lived in the home.

No injuries were reported and the cause of that fire is under investigation as well.
