Isabelle suffered her fatal injuries on the morning of 13 September while alone with Simpson, when Walker was upstairs in bed following a drink and drugs binge, the court heard.
Walker called 999 later that afternoon to say her daughter had collapsed at their home, with the two-year-old dying in hospital the following day.
The previously “happy and mischievous” girl was found to have a fractured skull and catastrophic brain injury, with doctors also discovering she was covered in bruises and suffered 21 broken bones in the weeks before her death.
Prosecutors said Isabelle’s abuse started shortly after Simpson arrived in her life, with the extent of her injuries so obvious her mother must have known what was going on.
They said Walker prioritised her new relationship over the safety of her daughter, allowing Simpson to spend time alone with Isabelle despite suspecting he was a paedophile.
Simpson claimed he had no motive for harming Isabelle, while Walker said she did not hurt her daughter and was unaware of any abuse.
