I think as long as it’s not a crime towards a child he has a chance. They are gonna prolly gonna wanna see court details etc, and he may have to file some waiver of some sort. ( I only say this because when I went to my k1 interview in Kingston, this is what I heard the consulate telling a guy). You can do more research on the USCIS website.
also, this is not legal advice as I am not a lawyer in no way, shape or form.
