A 19-year-old woman accused of arson was caught on a surveillance camera singing, "The fire department is going to be mad at me," police in a Philadelphia suburb say.
Amanda Gessner touched off 7 blazes in trash and brush between 3 a.m. and 5:45 a.m. Tuesday within blocks of where she lives in Upper Darby Township, police said.
Gessner was witnessed earlier in the evening at a local convenience store singing the ditty about the fire department. Her tune was caught on the store's surveillance camera, officials said.
One fire damaged a home where a family of four was sleeping. They escaped without injury.
Gessner is being held on $100,000 bail, charged with arson and related offenses.
Authorities said they have no reason to believe she is connected to the recent arsons in Coatesville, a few miles away.
