HOULTON — A Mars Hill man has been sentenced to 10 years in prison for trying to hire someone to kill his ex-wife.

Mark Stetson was sentenced Wednesday in Aroostook County Superior Court. He had pleaded guilty in January to solicitation of murder, solicitation of robbery, and solicitation of kidnapping.

Authorities say the 43-year-old Stetson was already in jail on charges connected to a dispute with his ex-wife early in 2011 when he offered to pay another inmate to kill his ex-wife and, if necessary, tie up their autistic son. The plan was to make it look like a robbery.

Stetson was also sentenced to four years of probation.

Stetson expressed remorse in court.
