Three firefighters have been slightly hurt battling a Houston-area apartment complex blaze that destroyed 19 units.
Investigators are trying to determine whether the fire late Friday afternoon was sparked by someone cooking food.
Two Cypress Creek firefighters were injured when a stairway collapsed. Officials say another firefighter hurt his arm trying to rescue the other two firefighters during the blaze in northwest Harris County.
Authorities say all three firefighters were transported to a hospital to be checked out.
