If my boyfriend violated felony parole with three weeks left, he got caught with fake pee, what is he looking at?

This is up to the parole board but yes they could send him back.

If his probation is revoked he will probably serve his original jail sentence. I am assuming that he had fake pee b/c his real pee would be positive for drugs. Most people on probation were sentenced to a jail term which was suspended and put on probation. So whatever that suspended jail time was is what he is looking at.

More prison time
