A massive fire destroyed an apartment complex under construction Wednesday morning in west Harris County. At least one firefighter was injured. Flames turned the morning sky orange just before sunrise. Heavy smoke could be seen from miles away. Two four-story apartment buildings were leveled by the 3-alarm fire off the Grand Parkway near Katy. There were 50 to 60 apartments in each one. A fire department spokesman said the fire was so big, they maxed out the water system early on and couldn't stop the flames from spreading to the second building. “The guys that could get close to the fire were driven back by raging heat so they couldn't get hose lines on the fire," he said. The complex had been under construction for six or seven months and appeared to be completed on the outside but the interior wasn't finished.
