The 999 call on September 13 reported a sick child; paramedics arrived within one minute and found Isabelle lying on her back at the foot of the stairs with no pulse, in Thornaby, Teesside.
A two-year-old girl named Isabelle Rose Welsh died from a massive head injury after suffering 21 bone fractures and sexual assault, prosecutors told a jury at Teesside Crown Court on June 23, 2026. Her mother, Alexandra Walker, 25, and Walker's boyfriend, Harrison Simpson, 22, are accused of carrying out a "prolonged campaign of violence" against the child in their small two-bedroom home in Thornaby, Teesside.

Paramedics arrived within one minute of a 999 call on September 13, 2025, finding Isabelle pulseless at the foot of the stairs, covered in bruises, with blood in her nappy and vomit on her face. She was transferred to Great North Children's Hospital in Newcastle, where she died in the early hours of September 14. Manchester Evening News
21 Fractures and a Fatal Blow to the Head
Doctors found 21 bone fractures in varying stages of healing when they examined Isabelle after her death, according to Lancs Live. Those injuries included broken ribs and limb fractures. The fractures at different stages of healing indicate the abuse happened over a period of weeks, not in a single event.
Prosecutors say the fatal injury was a massive head injury — likely caused by violent shaking or by striking her head against a hard surface. Lead prosecutor Richard Wright KC told the jury this was the "end point" of sustained abuse. Isabelle also showed signs of sexual assault. Her private parts were bruised, and bruising covered her head, neck, abdomen, and back. ITV News
Hospital Discharged Isabelle Just 11 Days Before She Died
Isabelle suffered a leg fracture on August 29, 2025. Walker took her to a GP and then a hospital on September 2 — eleven days before the fatal 999 call. Doctors were told the injury was accidental. Despite concerns raised by some medical staff, Isabelle was sent home with her mother, according to Sabras Radio.
The decision to discharge Isabelle is now a major point of scrutiny in the trial. The case is expected to trigger a National Child Safeguarding Practice Review to examine whether doctors or social services missed a chance to intervene. Wright KC argued that her pre-existing medical history — she was born with bilateral hip dysplasia and had surgeries in her first year — made the new injuries even harder to explain as accidental.

Simpson Moved Into the Home Within Four Months of Meeting Walker
Walker and Simpson had known each other for less than four months when Isabelle died, prosecutors said. Simpson quickly became a regular visitor to the family home on Hartington Close, Thornaby, spending long stretches of time with Isabelle. Lancs Live reported that prosecutors argue this rapid, unsupervised access gave Simpson ample opportunity to harm the child.
Wright KC told the jury that in a small two-bedroom home, both defendants must have known what was happening. Even if only one person struck the fatal blow, he argued, the other is legally responsible for failing to stop it. Walker is charged with murder, allowing the death of a child, and child cruelty. Simpson faces murder, rape, sexual assault, and child cruelty charges. Both deny all charges. ITV News
Community Mourns as Six-Week Trial Gets Underway
After Isabelle's death, around 200 residents gathered for a candlelight vigil and balloon release in Thornaby to support her biological father, Josh Welsh, who called her his "princess," according to The Independent. Her funeral was held on January 13, 2026, at St Paul's Church in Evenwood — the same day an inquest was opened and suspended pending the criminal trial.
The jury was sworn in on June 22, 2026, and the prosecution opened its case the following day. The trial at Teesside Crown Court is expected to last approximately six weeks. Key upcoming testimony will focus on medical experts explaining the dating of the 21 fractures — evidence that could prove or undermine the prosecution's claim of a sustained, weeks-long campaign of abuse.
