This is an all-too-frequent phenomenon because the availability of local resources are severely restricted.
Art 46B.071(b) would prohibit restoration commitment - which is good because that would cost the county roughly $35k and accomplish nothing.
Stictly civil commitments will result in too speedy release. Instead, look at 46B.102/103, or consider a guardianship and placement. If you call, I have protocols, forms, checklists for the court, etc. etc. etc. -- all were given to the judges in Region 2 earlier in 2012 by Brian Shannon and myself. NOte if you do a 102 commitment the court will control release and charges are not dismissed and will buy time equivalent to the max sentence (if a Class A, one year).
