The one thing that I know is it is expensive for a police department to expedite an inmate from one state to another. His attorney should be able to work out an agreement with Oklahoma for him to complete his sentencing there since he clearly violated probation on his felony drug conviction. However, jake.brown answered below, this will be based on his GOOD BEHAVIOR while in Oklahoma. You stated that he does not have any family and friends in Oklahoma and he lost his fiancee. This will be tough on him, because a part of being able to survive treatment, is to have family and friends you can depend upon in times of need. However, being that the drug offense was a felony and a dui is a misdeamenor, they may require him to return to Texas to complete his sentencing because a felony is a more serious charge than a misdeamenor. The question to ask is, you are his parent, do you live in Texas where he could complete his treatment and sentencing is probation is revoked? This could give him the family support he needs to complete his treatment program........
