Your cousin needs an attorney sooner than later. It may be tough to get a bond on these charges. Your cousin needs an attorney he can reveal the details of the case to, so the attorney can try and obtain a bond for him. It may be possible, although if a bond is granted, it is likely it will be a high bond, if a bond is set at all. It's too early to say whether he will go to jail or not. There are too many variables involved.
