Thomas Lee Elkins, 58, was last seen around 2:45pm at the Southeast Texas Transitional Center on 10950 Beaumont Highway, where he was living and electronically monitored, according to the Texas Department of Public Safety.
Authorities believe he escaped on foot but could ask other drivers for a ride.
Elkins has been convicted of kidnapping, aggravated battery, aggravated sexual assault and sexual battery and is considered violent by law enforcement. Now, he's wanted on a felony charge of failure to comply with civil commitment requirements.
Elkins has worked as a long-haul truck driver and would fit in around any truck stop.
He is 6 feet 3 inches tall and weighs about 200 pounds. He has blue eyes, gray hair, a distinctive Fu Manchu moustache, wears silver glasses for reading only, and walks with a limp. He has also been known to shave his head.
Anyone with information is asked to call local police immediately.
