A murdered grime star has been brought'back to life' using deepfake AI technology in a new music video to warn against the dangers of knife crime. Joshua Emmanuel Ribera, performing as Depzman, was stabbed to death outside a Selly Oak nightclub in Birmingham in September 2013. His mother, Alison Cope, is a prominent anti-knife campaigner and head of the Joshua Ribera Foundation. She worked with Jamal Edwards, before his death in February 2022, and various other artists and performers to recreate the rising grime star. The video uses deepfake technology to tell Depzman's story through a new song called Life Cut Short, describing his childhood, his career and the night that he died.
