A 288 is a very serious crime and requires the services of an attorney experienced in "sex crimes" defense. And even before they choose whether to formally charge your husband, you need to obtain qualified counsel ASAP! The truth is that if your husband was already arrested, then "probable cause" for the arrest must have come from somewhere! So, you need to take steps to try to protect your husband from making any statements while in custody, which only a lawyer can do once retained!
I would also be more than happy to consult with you on this matter as well. Simply follow the links to by website for my full contact information! And if retained, I would immediately contact the police to determine what is specifically happening here and advise the police NOT to speak to him without an attorney being present!
Either way, time IS truly of the essence here. As an aside, if you found my direction helpful, and if you feel appropriate; could you be so kind as to designate my answer as the “best” answer to your question? I truly wish you the best of luck in this matter and please feel free to call me toll free at (800) 200-4384 if you wish to discuss this further!
