Dutch police have received dozens of leads after using deepfake technology to virtually bring to life a teenager almost two decades after his murder. Sedar Soares was shot dead in 2003 while throwing snowballs with friends in the parking lot of a Rotterdam metro station. Now, with the permission of Sedar's family, they have made a video in which the teen asks the public to help solve the cold-case crime. In what Dutch police believe could be a world first, an eerily lifelike image of Sedar appears in the video as he greets the camera and picks up a football. Accompanied by stirring music, he walks through a guard of honour on the field, comprising his relatives, former teachers and friends.
