The state Fire Marshal's office is investigating whether a string ofrecent barn and vacant building fires in the county is the work of an arsonist.
A fire in Waterloo on Tuesday is the fourth suspiciousfire in three weeks involving vacant buildings, county fire records show.
Tuesday's fire occurred at a vacant house on Old Waterloo Road near Port Capital Drive.
The fire began at approximately 8 p.m., directly across from the site where someone set fire to a vacant barn onSunday.
Firefighters say the barn was a total loss; a damage estimate on
the two-story home was not available.

On March 10, a county Department of Recreation and Parks barn was set afire and destroyed in the 10500 block of Boones Lane in Ellicott City.

Fire marshals have not determined whether the fires are related and are continuing the investigation, said Bob Thomas, deputy chief fire marshal.
