But then what? It doesn't sound like he got sentenced to prison and had the sentence suspended or anything like that so that if he did violate his parole then he'd go to jail. If he violates his parole, what does he get? Longer parole?
I don't know exactly how the procedure works in Texas, but when someone is sentenced to probation and violates that probation, they can be brought before a judge (either the judge who sentenced him or an administrative judge) for a probation revocation hearing. If probation is revoked, the person will then be brought before a judge (this time, typically the same judge who sentenced him) and re-sentenced.
