Day 10 - Toddler murder and sexual abuse Trial.
Over 100 internal and external injuries on toddler explained to the jury
Court hears how toddler Isabelle Welsh was beaten, sexually violated and killed, say prosecutors
Teesside Crown Court sat in stunned silence as jurors were shown a macabre body-map of tiny Isabelle Welsh:
- Twenty-one bones snapped at different times;
- Ninety-seven cuts, bruises and scratches blotched across her face, torso and limbs;
- A vicious tear to her genital area;
- A fatal skull fracture that left the two-year-old’s brain bleeding and her heart stuttering to a stop on 14 September 2025.
Home Office pathologist Dr Sam Hoggard told the jury the child’s “catalogue of trauma” could only have come from “repeated, deliberate violence” visited upon her “over at least three separate assaults in the weeks before she died.”
Specialist eye-doctor Dr Jo McPartland added that the toddler’s eyes were riddled with so many haemorrhages “I lost count,” a classic sign, she said, of ferocious shaking.
Prosecutors allege that violence—and a final, murderous assault—came from the very people sworn to protect her: Isabelle’s mother, Alexandra Walker, 25, of Hartington Close, Thornaby, and Walker’s new boyfriend, Harrison Simpson, 22, of Greenham Close, Thorntree, Middlesbrough.
Both stand accused of murder. They also face charges of causing or allowing the death of a child, two counts of assault by penetration committed between 10 and 14 September, and cruelty to a child under sixteen.
Each defendant denies every allegation, insisting Isabelle’s catastrophic injuries were accidental.
From the witness box, Dr Hoggard painted a picture of sustained torture. Isabelle’s arms, legs, spine—even her skull—had been broken and re-broken as the weeks ticked by.
The fatal blow, he said, almost certainly occurred on the day emergency services were called: Isabelle was “gripped and shaken with vigour”, then slammed, head-first, against “a wall or floor”, causing her skull to crack and her brain to haemorrhage.
Earlier, jurors heard that the toddler’s genital injuries included a laceration to her mole. “The only plausible explanation,” Dr Hoggard declared, “is that she was sexually assaulted before she died.”
Simpson, seated in the dock beside Walker, occasionally shook his head; Walker stared at the floor.
Their defence teams argue that Isabelle’s injuries were the tragic result of clumsiness and a series of unfortunate tumbles.
But lead prosecutor Imogen Eastham-Brown scoffed at the suggestion. “Ladies and gentlemen,” she told the jury, “children aged two do not rack up twenty-one fractures—at different stages of healing—by falling out of bed.
They do not sustain intimate injuries by accident. Isabelle was brutalised, sexually violated and, ultimately, murdered.”
Judge Mr Justice Adams reminded jurors that the defendants are “entitled to the presumption of innocence” until the prosecution proves its case beyond reasonable doubt.
The trial continues, with harrowing medical testimony expected to dominate the week ahead.
