(Thursday May,25) Investigators say they now know who set a fire 12 days ago that heavily damaged a home in Jessup. The arrest came just after three Thursday afternoon at the State Police Barracks in Dunmore. Troopers say 48-year-old Mary Beth Malewicz set fire to her own house in the 500 block of Third Street back on May 13th. Investigators tell us Malewicz set the fire because she wanted to collect insurance money from the damage. One firefighter was hurt while trying to put out the flames.
