Arson was the cause of fires over the weekend in two vacant houses and a barn in northern Harford County, the state fire marshal's office says.
The fires occurred two days after deliberately set fires destroyed a home and a Boy Scout cabin in the same area. In the past five months, there have been about a dozen suspected or determined cases of arson in northern Harford, and all probably were set by the same person or persons, says Bob Thomas, spokesman for the fire marshal's office.
On Saturday about 11:20 p.m., firefighters were called to a fire at a two-story frame home on Castleton Road in the Darlington area. The fire destroyed the house, which was worth about $20,000 and had been vacant about five years, Mr. Thomas said yesterday.
