Your brother-in-law could be looking at two potential punishments. He could be punished by DOC for breaking the terms of probation and he could be punished if he is convicted of the new charge. Criminal impersonation in the first degree is what's called an unranked felony. That means that if he's convicted he could get anywhere from 0 to 365 days in jail. In the end, his sentence will depend on his criminal history, the recommendations of the parties and the judge's decision.
