He also named himself the Scalp Serial Killer because he beheaded his victims. He murdered an American woman Melissa Halstead who had moved to England to start a new life. He also murdered a British woman Paula Fields. Sweeney murdered Melissa Halstead in Amsterdam where they had moved in 1990, he abused her throughout their relationship. Melissa Halstead’s torso was discovered in 2008. He was also accused of murdering American actress Dominique Dunne of Poltergeist fame and the daughter of famous writer Dominick Dunne. Sweeney met Dunne when he was in California working as a sous chef. He was convicted of their murders in 2011. Sweeney was given a whole life term, which in London, England means life in prison without parole. John Sweeney died in August of 2026.

The Early Childhood of John Sweeney

John Sweeney was born October 13, 1956, in Liverpool, England. He spent much of his early childhood living with his mother and was born into a working-class family. His early years were marked with signs of behavioral issues. He left school at an early age and began to work in the construction industry. Sweeney began to use aliases, a pattern that would later help him evade police. Sweeney married and had two children, but the relationship ended because of his abusive behavior. His former wife reunited with him, but the abusive behavior continued. The marriage ended in divorce once again. It was at this point that Sweeney moved to London, England and began a life of crime.

The Less Dead

A term coined to refer to many serial killers’ victims, who belong to marginalized groups of society. They lack prestige or power and generally come from lower socioeconomic groups or members of their neighborhoods and are generally not missed when they are gone. Examples are sex workers, the homeless, vagrants, migrant farm workers, homosexuals, the poor, elderly women and men, and runaways. They are often vulnerable in locations they frequent, and easy to lure and dominate. Most do not come from rich backgrounds or prominent families, which makes them easy targets for predators.

The Victims of John Sweeney

• Paula Fields, 31

The Survivors of John Sweeney

• Anne Bramley
• Delia Balmer

Upon Sweeney’s arrest, the authorities found hundreds of violent paintings and poems at Sweeney's home, including artwork depicting a bloodied axe and references to himself as the "Scalp Hunter". Police suspected he had murdered other former partners who had not been seen for years. He had previously been jailed for attempting to murder former girlfriend Delia Balmer in 1994 in an axe attack in London. The families of the victims tried to get the authorities to intervene to no avail. These women were in the less dead category.

Lady Justice

Sweeney’s children were appalled to find out that their father was a serial killer. John Sweeney, 69, was serving a whole-life sentence after being convicted in 2011, for his former girlfriend’s murder. He has been accused of other murders which he failed to acknowledge before his death on August 14, 2026. Because Sweeney is dead does not mean that his suspected murder cases will be closed. With DNA technology there is still hope that his victim’s families will find justice. It is a stain on society that the victims themselves did not find justice while they were alive.
