A mother, Alexandra Walker, 25, is on trial accused of sexually abusing and murdering her two-year-old daughter, Isabelle Welsh. Prosecutors say Walker waited before contacting emergency services after Isabelle became injured and was dying. The court hears that, at the time Isabelle was suffering, Walker was smoking a cigarette. It is also alleged that she then used Google to search a question about why her toddler was bleeding. The case centers on what Walker did and when she did it during the period leading up to the emergency call, as well as the circumstances of Isabelle’s injuries. The evidence described in court relates to her actions shortly before the call to 999 and the focus on whether there was a delay. The report also references the presence of a new boyfriend, though the specific role attributed to him is not detailed in the provided excerpts. The trial proceeds as the court weighs the allegations against Walker.
