KILLEEN, Texas (FOX 44) – UPDATE: The fire that closed a part of East Rancier Wednesday morning remains under investigation.

Officers had temporarily closed both eastbound and westbound lanes on Rancier Avenue between Alexander Street and Stewart Street while firefighters were working to control the blaze.

The fire department got the call at 5:37 a.m. about a fire in the 1400 block of East Rancier. A resident driving by reported seeing dark smoke in the area near a commercial building.

An initial alarm sent three engines, a ladder truck, rescue truck and ambulance with a total of 20 personnel. The first units arrived in about five minutes and determined that the smoke was coming from a one-story vacant commercial office building. Because they were having difficulty locating the seat of the fire, a second alarm was pulled and two more engines with additional help were called to the scene.

The fire was then brought under control in about fifteen minutes with a crew remaining on the scene an additional two hours dealing with heavy charring and fire damage throughout the structure.

No one was found in the building and there were no injuries.

The road closure was made necessary because the closest fire hydrant was across the street.

Fire investigators reported there had been no utilities connected before the fire and the cause of the fire remained unknown and under investigation.

Travelers were urged to seek alternate driving routes as first responders worked the scene.

This is a developing story. FOX 44 News will have more information as it becomes available.
