Respectfully, any specific answer would need more information then you posted. The sentence would depend on the grade of the offenses that he pled to or he was convicted of, the prior record of the perpetrator, and other case specific facts that you may not be aware of. The best way to get a more specific answer is for you to contact the prosecuting authority and ask to speak to the person prosecuting the case. Good luck.
