If the information is not posted online, you can contact the Clerk of the Courts where the sentence was imposed and apply to receive all of the public filings on the case. You can even petition the judge for that information. If that is not a route you want to take, you might try calling the facility and ask to speak with the case manager, counselor or unit team secretary to get more information.
