You need your attorney to get involved.
No legal advice is given here. My responses to questions on Avvo are never intended as legal advice and must NOT be relied upon as if they were legal advice. I give legal advice ONLY in the course of a formal attorney-client relationship. Exchange of information through Avvo's Questions & Answers forum does not establish an attorney-client relationship with me. That relationship is established only by joint execution of a written agreement for legal services. I am only licensed in the States of California and New York and the District of Columbia
There is someone missing from this discussion: the man's attorney. Surely, the man must have one, whether privately retained or through the office of the federal public defender. It's not up to the "PO" to decide what is or is not acceptable evidence on this issue, it's up to the judge, and that judge must consider the input of the man's attorney.
If this man somehow, through some terrible twist of fate, does not actually have an attorney-- then get the man an attorney, pronto. That will go much farther to solving this crisis than posting about it here.
Any answer provided on Avvo, including this one, is a general answer about a legal question, not specific legal advice. Different lawyers may analyze this or any other matter differently, especially if there are additional facts not reflected in the question. I am not your attorney until retained by a written retainer agreement signed by both of us. I am licensed in the state of California and the Central District of the Ninth Circuit.
