Some websites have the sentencing information. For the MCI facilities, use this link and enter your inmate's name: http://www.mass.gov/eopss/agencies/doc/locate-an-offender.html.
Another avenue is to call the Clerk of the Court where he was charged. You can actually talk to the judge's secretary and get all of the court documents (might have to pay for the printing) regarding the case.
