FRESNO, Calif. (KFSN) -- Fire crews are investigating what caused a house fire in Tulare Thursday morning.
It happened just after 3:00 a.m. on Bardsley Avenue near West Avenue.
Firefighters say the flames quickly consumed the abandoned farmhouse.
The roof caved in during the blaze, so firefighters worked to put out the flames from a distance to keep the fire from spreading.
Fire officials believe homeless people may have started the fire.
The cause is still under investigation.
No one was injured.
