HUNTSVILLE, Texas (KIAH) — The prison unit in Huntsville caught fire overnight and still burns Friday morning as fire crews work diligently to put the fire out.

CW39’s Kara Willis and Seth Kovar are bringing us updates throughout the morning. We talked with the fire chief there in Huntsville LIVE on air for an update.

“The Walls” unit caught fire about 2:30 a.m. Friday morning. Heavy smoke was reported. Crews arrived to find heavy fire coming from one unit. Units have knocked out the main body of fire.

All inmates have been evacuated from the area to another facility and are accounted for. No word on where the main fire started. As it is a state facility, the fire marshall is on the scene still investigating. On scene, a fire coming from an old tower can be seen.

This is pretty significant so it will take some time.

No word on the cause of the fire at this time.

Smoke can still be seen coming from the tower in front of the facility. Most of the heavy smoke and the bulk of the fire has been put out, which is good news for this historic building. The facility is where executions in the State of Texas take place there. It was established in 1845. That doesn’t mean this building was necessarily built then, but this is an old structure and it’s definitely taking on a lot of fire damage this morning.

The facility holds about 1,700 inmates. There were 320 inmates on-site at the time the fire started around 2:30 a.m. this morning. They have all been moved to safety. No injuries have been reported.

The Texas Department of Criminal Justice public information officer is coming in from Galveston, so stay tuned in to CW39 Houston for more on this developing story.
