Frederick County fire investigators are looking into three separate fires, including a car that was intentionally set ablaze in a motel parking lot.
The county fire marshal's office says the fires occurred during a span of six hours. The first happened late Friday night in Emmitsburg, where a detached garage caught fire. The cause is undetermined.
The burning vehicle was found early Saturday morning in the parking lot at the Travelodge in Frederick. Investigators determined it was a case of arson.
The third fire was accidental and damaged a house in Frederick. No one was injured.
