A man described as an ex-lover has been charged with the murder of a New York mom who was savagely stabbed to death in her basement and whose body was later found in a duffel bag, authorities said Thursday. David Bonola, 44, was a handyman who’d done work at the Queens home of 51-year-old Orsolya Gaal and her family. Officials say Bonola not only confessed to murdering Gaal, but also said he’d had an “intimate affair” with her for two years.
