A two-year-old girl died after sustaining fatal injuries in an incident involving her mother and the mother’s boyfriend, a court has heard. Alexandra Walker, 26, was sentenced to life imprisonment at Teesside Crown Court on Thursday after being found guilty of the murder of her daughter, Isabelle Welsh, and child cruelty. Walker’s boyfriend of four months, Harrison Simpson, 22, also received a life sentence with a minimum term of 28 and a half years following convictions for murder, child cruelty, and sexual abuse of a child.
Isabelle suffered an unsurvivable head injury on the morning of September 13, 2025, and died in hospital less than 24 hours later. According to Ms Justice Norton, the child’s injuries were consistent with being violently shaken and either hitting her head against a hard surface or being swung by the legs into a wall or piece of furniture. The judge criticised medical professionals who, influenced by Walker’s falsehoods, did not initiate safeguarding procedures that might have saved Isabelle’s life.
Walker repeatedly misled medical staff to conceal a pattern of assaults, presenting false information about her education, health, and drug use. She delayed seeking emergency medical help, initially believing Isabelle to be dead and attempting to devise a plan before calling 999. The call was reportedly made only after Walker’s stepfather insisted that Isabelle required urgent medical attention. Paramedics found the toddler covered in blood and bruises upon arrival.
The court was told that Walker lied “from start to finish,” including fabricating claims of having breast cancer and denying drug use despite evidence to the contrary. Both she and Simpson were arrested shortly after Isabelle was admitted to hospital.
In a statement released by the family, Isabelle’s relatives expressed profound grief over the loss, saying the child “should have had her whole life ahead of her” but was “taken from us in the most heartbreaking way.” The case highlights concerns about child protection and the challenges faced by medical personnel in identifying and responding to abuse when caregivers provide deceptive information.
