More than a decade after a Bustleton man's body was found floating in the Schuylkill River, a woman allegedly involved in his death has been arrested, the Philadelphia District Attorney's Office said Wednesday. Melanie Morat, 30, was taken into custody this week at her Frankford home after police developed new information in the unsolved killing of 69-year-old Vito Maglio.
