Assuming that the shoplifting case is in San Diego, I would contact the court and let them know he is being held. You could also gather the information regarding his mental health issues and why he was not compliant. Ideally, he should clear up the criminal matters here before moving out of state so warrants are not following him. That could make it difficult for him to obtain housing or obtain services. If you can get a conservatorship because he is not competent to handle his own affairs, that may be the best bet but that will be something else for you to determine. Such a difficult situation, good luck.
