PARSONSFIELD, Maine -- Authorities say a man used a front-end loader to pick up and drop his son's mobile home repeatedly during a family dispute and stopped only when he learned his 7-year-old grandson was inside. The York County sheriff's department said John Bubar, 50, was involved in a dispute with his son, Michael, 27, on Sunday over rent payments and debris in the yard. The elder Bubar was arrested. His grandson wasn't hurt.
