Janice Nix manslaughter conviction confirmed in UK cold case of 1978 child killing after new evidence reopened investigation

A UK court on Tuesday convicted Janice Nix, a 67-year-old woman of Rodenhurst Road, SW4, in connection with the Janice Nix manslaughter conviction over the 1978 killing of her five-year-old stepdaughter, Andrea Bernard, following a landmark cold case review by Metropolitan Police investigators.

The Isleworth Crown Court found Nix guilty of manslaughter after jurors heard how Andrea Bernard died in July 1978, nearly six weeks after being admitted to hospital with severe burns covering 50 per cent of her body, caused by immersion in scalding bath water at a home in Thornton Heath, London.

At the time of the incident, a coroner ruled Andrea Bernard’s death as accidental, attributing it to sepsis arising from burn injuries. However, decades later, fresh evidence and renewed testimony led investigators to reopen the case, ultimately culminating in the conviction.

Police said the breakthrough came after Andrea Bernard’s older brother, Desmond, who was eight at the time of the incident, came forward as an adult to provide new testimony alleging a pattern of abuse within the household.

According to the Metropolitan Police, Desmond revealed that he had previously concealed the truth about the incident, saying he had been pressured into silence following repeated physical abuse and threats.

Detective Inspector Louise Caveen of the Met’s Cold Case Homicide Team described Desmond’s decision to speak out as pivotal, noting that his courage enabled investigators to pursue justice in a case that had remained unresolved for more than four decades.

The Janice Nix manslaughter conviction also included findings related to the assault and ill-treatment of Andrea Bernard’s older brother between 1975 and 1978, further strengthening the prosecution’s case.

Authorities said the ruling underscores the commitment of law enforcement to pursue justice regardless of time elapsed, particularly in cases involving vulnerable victims.
