A New Hampshire man who pleaded guilty to setting fire to a Baptist church building has been sentenced to a quarter-century in prison.

Anthony K. Boisvert appeared in Grafton Superior Court in North Haverhill, New Hampshire Monday pleading guilty to nine charges of arson, assault and witness tampering, according to The Valley News.  He apologized to the church, but denied some of the accusations made in a probable cause affidavit, according to a report from the Union Leader.

Boisvert’s sentence is related to crimes committed in 2016 including arson at the First Baptist Church of Lebanon.  Prosecutors say he stabbed two people in an attempt to stop them from testifying.

The Church had been at the location for 145 years. The Associated Press reports the remains of the church were demolished following the fire.

Family members in January told WMUR they believe Boisvert suffers from mental illness and he needs help, not prison.
