Deputy State Fire Marshals have charged a Mechanicsville man with setting his home on fire early Monday morning and later connected him to setting his parents' car on fire Saturday morning. Michael Robert Guy, 47, was arrested shortly after the fire with the assistance of the St. Mary's County Sheriff's Office.
Just after 1:00 a.m. on June 23, 2025, the Mechanicsville Volunteer Fire Department was dispatched to 27099 Morganza Turner Road for a dwelling fire. Upon arrival, firefighters discovered heavy fire from inside the attached garage, quickly spreading to the remainder of the home. The home is considered a complete loss, and the Office of the State Fire Marshal was requested to determine the origin and cause.
During their investigation, Deputy State Fire Marshals concluded that the fire was intentionally set and identified Guy as the suspect.
The St. Mary's County Sheriff's Office assisted in taking him into custody, and he was transported to the Maryland State Police Leonardtown Barrack.
As the investigation continued and during their interview with Guy, he told investigators that he had set his parents' 2003 Cadillac on fire Saturday morning near the intersection of Ted Drive and Ted Circle in Avenue. Coincidentally, that fire was also under investigation by the Office of the State Fire Marshal.
Guy was charged with first and second-degree arson and transported to St. Mary's County Detention Center, where he is currently being held without bond.
