A KENSINGTON grandmother who was the primary caretaker for her 8-year-old grandson was sentenced to 57 months in a federal lockup Monday for dealing prescription painkillers and other drugs out of her home.
Diane Donnelly, 45, whose residence was within 1,000 feet of the Henry A. Brown Elementary School that her grandson attended, was arrested in May 2011 after cops said she illegally distributed controlled substances to an undercover Philadelphia police officer. She has been in federal custody since her arrest.
