RICHMOND, Va. (WRIC) — Investigators are trying to determine what sparked a house fire in Forest Hill that left a family homeless Thursday morning. 

Fire crews were called to the house — located on Forest Hill Avenue near Fairlee Road — at around 6 a.m. after someone walking by the home noticed smoke. 

Crews responded to find nothing showing from the home, but later located flames underneath the floor. It took firefighters roughly 30 minutes to mark the blaze under control.No one was home at the time of the fire, but the homeowner’s sister told 8News that it’s an emotional time for their family, and that Thursday’s fire was also a painful reminder of a tragic incident that occurred two years ago.

“I have to be strong for her right now,” said the homeowner’s sister, who was too emotional to go on camera. “They’re telling us that there’s smoke damage, but that is all that we know right now.”

The homeowner’s sister explained that she lost her 26-year-old son two years ago in a fire at St John’s Woods Apartments. ​​​​​​​”It’s a little bit much for her right now. I’m just trying to be tough for my sister, I’m trying to hold up for her.”

Staying strong, while also wondering how the flames started. During Wednesday’s thunderstorms, a large tree came crashing down in the backyard of the home, knocking out all of the power.

“There’s no electricity, we are baffled right now,” she added. “We don’t know how it happened, but no one was home and that’s a good thing.”​​​​​​​The living room suffered extensive damage, and it is unclear when the family will be able to return to their home. 

Investigators are still working to determine what caused the blaze.
