PORTLAND — A New Hampshire resident convicted of robbery and brandishing a firearm during a January 2016 home invasion in Lyman has received a 10-year prison sentence.

Xavier Watson, 24, of Brentwood, New Hampshire, was sentenced Wednesday in U.S. District Court by Judge Jon Levy to 121 months in prison and three years of supervised release following convictions for robbery and brandishing a firearm in furtherance of a crime of violence, according to a press release from Acting U.S. Attorney Richard Murphy.

Watson pleaded guilty to the charges last October.

According to court records, early on Jan. 15, 2016, Watson and four other men drove from New Hampshire to Lyman to commit a home invasion robbery of a licensed medical marijuana caregiver.

Police say that Watson and three of the men broke into the home, brandishing two firearms – a pistol and a shotgun. Watson possessed the pistol and co-defendant Vincent Casazza allegedly possessed the shotgun.

Five victims were present in the residence and during the altercation. Watson was accused of physically assaulted a male victim.

According to records introduced by the government at the sentencing, Watson also sexually assaulted a 17-year-old female during the robbery. He and his co-conspirators also were accused of stealing three firearms from the residence, as well as cash, marijuana, various electronics, and other items of value.

Watson’s co-defendants, Casazza, Reynan Mora, and Andre Thomas, have pleaded guilty in federal court to their involvement in the robbery, but have not yet been sentenced.
