A 58-year-old woman was in extremely critical condition Wednesday night after her home was intentionally set on fire by a mentally disturbed man in North Philadelphia, police said. The blaze started in the 1700 block of West Girard Avenue shortly after 9 p.m. when the 30-year-old man, who may be the woman's son, set her apartment on fire with lighter fluid, authorities said.
