A Riverdale volunteer firefighter pleaded guilty Tuesday to sneaking into a vacant home and setting a sofa on fire with a flare so that he and other firefighters could return to help put out the blaze.

Jerome Engle, of Bowie, faces up to 10 years in prison but is more likely to receive a penalty closer to the guideline recommendation of one year in jail at his sentencing next month, said Prince George’s County State’s Attorney Glenn F. Ivey. Prosecutors will seek $200,000 restitution from Engle.
