SCARBOROUGH — Kelly McVan and Caitlyn Farrell got an early glimpse of what they would experience over the next 48 hours. Soon after arriving at Gosnell Memorial Hospice House for a rare educational experience, the two University of New England medical students sat by a window and witnessed a deceased patient being removed from the facility by a funeral director. Several hospice staff members lined the snowy walkway as the body was wheeled out to a dark hearse.
