BARRE — The Roxbury man convicted of setting the 2010 Memorial Day fire that burned the Aldrich Block has pleaded guilty to his latest crimes.

Nicholas Witham, 19, was sentenced Wednesday in Washington County criminal court in Barre to six years in jail for two violations of probation, possession of alcohol by a minor, and supplying alcohol to minors, all misdemeanors.

He will be placed on furlough and live at his mother’s home as soon as the Department of Corrections approves the residence as an acceptable place for him to live. He was on probation for arson and burglary convictions in August, but his probation was revoked at Wednesday’s sentencing.

The alcohol convictions result from a drinking party at the Highgate apartments in September 2011. Witham’s probation violations stem from not letting his probation officer know where he was living, violating his curfew, and failing to meet his probation officer as directed.

As part of the plea agreement, two charges of possessing child pornography and three charges of piercing without a license were dropped.
