He should not do anything without seeing a solicitor that practices in criminal law.
Because of his condition he may not go to jail but this has to be handled carefully.
He should contact the law society in your state and get a referral to a solicitor that practices in Criminal law and get very details advise on how this should be handled.
Also a medical report will have to be obtained from his treating doctor.
I hope this makes sense and is of assistance, If there is nothing further
thank you for using my services.
If I have missed anything, or you have any further questions please let me know
If there is anything else in the future please do not hesitate to ask.
