Arson investigators look into fire in SW Houston
HOUSTON
Flames broke out before 6am at the Forest Green apartment complex at Fonville and Fondren.
Investigators believe someone started the fire on the outside of the building and it quickly took over the first and second floors. They don't think it was started by coals from a BBQ pit or even fireworks.
