It is impossible to answer your question from the facts you have provided. It appears as though the individual in question has not yet been tried. The most likely outcome is that the case will be resolved through some kind of plea bargain, which is how nearly all criminal cases are disposed of. It is also possible that the charges will be dropped if the witnesses are uncooperative. It's anybody's guess.
