The fire broke out around 4 a.m. Sunday in the Big Oaks subdivision near Lake Conroe.
When fire crews arrived at the home on Lakeway Drive, they saw flames shooting from the roof.
While putting out the flames, firefighters found a body. Family members confirmed to Local 2 that the homeowner, Estanislao "Sam" Torres, died in the fire.
