The Annaville and Bluntzer volunteer fire departments were called in to assist the Robstown Fire Department with a large house fire Monday, which left a Robstown couple without a home.

Patrolman Anthony Jewell, with the Robstown Police Department, said he responded to a call around 2:35 p.m. about smoke coming from a home on the corner of East Avenue D and North Fourth Avenue.

"The owner was inside at the time of the fire," Jewell said. "She was walking out (of the home) when we arrived."

Fire Chief Richard Gonzalez said passerbys noticed smoke coming from the home and knocked on the front door to alert the woman, who was the only one in the home at the time of the fire.

Officers said they made sure no one else was inside the home before the woman walked to a neighbors home a few houses down from the scene of the blaze. She was not injured in the fire, Jewell said.

Police and fire personnel, as well as Robstown Emergency Medical Services, blocked off the streets leading to the fire for more than an hour while fire fighters battled the blaze and large plumes of black smoke.

Gonzalez said some firefighters had to be assisted by Robstown EMS after being overcome by the heat and smoke while trying to extinguish the fire, though no serious injuries were reported at the scene.

The home and a second structure behind the house, as well as two vehicles in a carport at the rear of the primary residence, were heavily damaged in the blaze and may be a total loss, officials said.

The cause of the fire is still under investigation.
