Aaron, Devastated,
I appreciate you both taking the time to respond. I found both replies to be helpful. I am planning on speaking directly with my son's probation officer on Monday.
I have drafted an "Eviction Notice" and was advised to discuss it with his PO before presenting it to him. I would like to make sure I have covered all bases just in case he does not react appropriately.
Thanks again... I can post results if anyone's interested.
