Delia Balmer’s ex-boyfriend wasn’t just a scruffy stoner with a pet tarantula and a sketchbook full of gruesome drawings: he was a murderer. The infamous ‘Canal Killer’ John Sweeney told Delia he had killed before – but after the police ignored her repeated warnings, she ended up barely escaping with her life. This is the harrowing true story behind hit ITV drama ‘Until I Kill You’: one of horror, survival, and a broken justice system that let a monster slip through the cracks.
