Nearly 50 Years Later, Stepmother Convicted in Scalding Bath Death of 5-Year-Old Girl

In a case that stretched across nearly five decades, a London woman has been found guilty of manslaughter for the death of her 5-year-old stepdaughter, who was placed in a scalding hot bath back in 1978.

Janice Nix, now 67, was convicted Tuesday after a jury in London deliberated on charges stemming from the death of Andrea Bernard. The child died in July 1978 from sepsis, about six weeks after suffering severe burns to half her body at the family home in Thornton Heath. At the time, authorities ruled the death accidental. But that finding unraveled in 2022 when Andrea's older brother, Desmond, walked into a police station and told officers that Nix had killed his sister and forced him to lie about it.

The case highlights the quiet persistence of cold-case investigations and the heavy weight of childhood trauma. Desmond, who was 8 when his sister died, told police that Nix routinely beat the children and made them eat cat food as punishment. He said she instructed him to claim Andrea's death was an accident, promising that if he lied, "she would never beat me again."

For decades, the truth remained buried. Then, in September 2022—44 years after Andrea's death—Desmond came forward, setting off a painstaking review by the Metropolitan Police's cold case team. Detectives found that hospital records had not been retained, and many potential witnesses had died or moved away. But a short coroner's report from 1978 contained an account from Nix that, according to Det. Constable Fran Homer, had "startling differences" from the story she told decades later.

Nix had claimed the bathwater overheated because of a broken boiler and that Andrea was able to hold a conversation after being scalded—claims experts later discredited. At trial, Nix admitted giving a false account at the time, saying she was gardening and not supervising the 5-year-old, and that she had panicked. But Desmond testified that on June 6, 1978, Nix told Andrea she was in trouble for not cleaning the house. He recalled hearing his stepsister say the bath was too hot, followed by Nix shouting, "Get in the bath," then splashing and screams.

Nix, who had previously written a memoir about her past as a drug dealer known as "Mama J" and spoken about reintegrating after prison, was arrested at a London airport in February 2025 upon returning from Antigua and Barbuda. The same day, she was charged with manslaughter and child cruelty relating to Desmond between October 1975 and June 1978. She remains in custody and will be sentenced at a later date.

Prosecutors acknowledged the unusual challenge of pursuing a homicide case from the 1970s. "Dealing with homicide cases in the modern day is very, very different," said David Malone, deputy chief crown prosecutor for the Crown Prosecution Service in London. "We look at all of the data we have in our telephones, CCTV, the audio. There's that wealth of documentary evidence. And of course, when you go back such a long time, witnesses pass away."

Police said Nix would not have been brought to justice without Desmond's courage. Homer described it as "heartbreaking" to hear of the guilt he carried, and added that he seemed determined to be "the voice of Andrea she didn't have."
