- Simpson, Walker's boyfriend, was also convicted of sexually assaulting Isabelle, while Walker was cleared of that charge.
- Cleveland Police admitted failing to execute an arrest warrant for Simpson for 18 months, which had been issued after he breached a non-molestation order, prior to Isabelle's murder.
- The force acknowledged the delay was "far from adequate" and has since implemented changes to its processes for managing outstanding warrants.
- Simpson was sentenced to life imprisonment with a minimum term of 28 years and six months, and Walker received a life sentence with a minimum of 22 years.
