A new documentary explores the mystery of who was responsible for the death of George Polk, a CBS News reporter. Construction workers in Thessaloniki, Greece, stumbled upon a mass grave containing 33 sets of bones believed to be victims of executions during the country’s Civil War. The discovery has prompted descendants to visit the site, leaving flowers and requesting DNA testing to identify and retrieve the remains of their relatives. The excavation sheds light on the brutal conflict that claimed thousands of lives and left behind a legacy of repression and societal divisions. The finding has sparked a debate on how to address the past, with some preferring to confront the country’s ghosts while others choose to ignore them. The city officials are planning to conduct DNA testing on the remains to identify the victims and return them to their families.
