Until I Kill You: The True Story of Delia Balmer & Serial Killer John Sweeney

Delia Balmer survived an axe attack by serial killer John Sweeney , the "Scalphunter", but her hardest fight was against a system that refused to listen.

Before John Sweeney made headlines as the dismemberment killer responsible for the murders of Melissa Halstead and Paula Fields, Delia Balmer handed law enforcement his murder confession, his bloody sketchbooks, and a blueprint of his violence. Despite surviving a four-day hostage ordeal in her Camden flat, institutional failures left Sweeney free on bail leading to a terrifying ambush on December 22, 1994.

In this episode of When Killers Get Caught: The Survivors, host Brittany Ransom details Delia Balmer's unbelievable grit, the psychological reality of coercive control, the decade-long fight to secure a Whole-Life Order, and how Delia reclaimed her narrative through her memoir Until I Kill You.
