VERSHIRE — Investigators believe a man lit his ex-wife’s house on fire in Vershire and then shot himself.

Police found 53-year-old Collin Barry collapsed outside the home Wednesday morning with a gunshot wound to the head and burns on parts of his body.

No one else was injured.

WCAX-TV reported that Barry is being treated at a Boston-area hospital.

Investigators expect criminal charges to be filed against him.
