Millions watched in horror as popular and sexy ‘vlogger’ Brooke Marks was murdered on-camera during one of her live webcasts. Her body was never found. But what happened in the weeks before might be the most depraved crime of all. These are the days and nights leading up to Brooke’s brutal death: her casual hook-ups with various guys, cruel insults to other women and, perhaps most gruesome, the faceless cyber-stalker who forced Brooke to watch as those closest to her were systematically tortured, slaughtered, and defiled. It's a merciless wake-up call for the viral video generation.
