MT. VERNON – Officials believe an early Monday morning fire that heavily damaged a garage in Mt. Vernon may have been intentionally set.

Firefighters were able to quickly knock down the blaze that was discovered around 3 a.m. Monday morning in the 400 block of South 19th Street and prevented it from spreading to the nearby home.

The State Fire Marshal’s office was called to help Mt. Vernon Fire Investigators determine the cause of the fire.
