A warrant left unexecuted
Cleveland police did not manage to arrest Harrison Simpson even though a warrant for his arrest was issued in March 2024. The warrant was issued after Simpson failed to appear in court for breaking a non-molestation order. That order had been put in place after Simpson was reported for harassing and threatening another woman. The failure to act on the warrant was highlighted during a recent court case involving Simpson’s later crimes.
A police statement explained that they tried multiple times to locate Simpson and execute the arrest. Despite their efforts, they were unable to do so. They acknowledged that the length of time Simpson went without being apprehended was far from acceptable. A full review was launched after Simpson was later arrested in connection with the murder. The review aimed to understand what had gone wrong and how to avoid similar failures in the future.
The death of Isabelle Welsh
Isabelle Welsh passed away on 14 September 2025 after enduring a lengthy period of abuse by her mother, Alexandra Walker, and Simpson, her mother’s boyfriend. The two-year-old had 21 fractured bones and her body was covered in bruises. She collapsed in her home in Teesside, where she lived with her family. The court heard that the abuse she suffered was part of a prolonged and brutal campaign that ultimately led to her tragic death.
During the sentencing hearing, Justice Norton described the toddler’s death as extremely disturbing. He said the abuse Isabelle suffered was not only cruel but also methodical. A family statement expressed deep sorrow, saying that Isabelle, who was full of life, was taken from them in a way that left them heartbroken. Her family said she should have had her whole life ahead of her, but she was denied that future.
Sentencing and reforms
Simpson and Walker were both sentenced to life in prison. Simpson was given a minimum of 28 years and six months to serve, while Walker must serve a minimum of 22 years. The sentences accounted for time they had already spent in remand. Simpson was also convicted of sexually assaulting Isabelle before her death, while Walker was found not guilty of that charge. The judge made it clear that the sentences reflected the severity of their actions.
Cleveland police admitted to making changes in their procedures to prevent similar failures. The reforms include better monitoring of outstanding arrest warrants and increased supervision. These efforts aim to strengthen their ability to respond to legal orders and protect the public. The police statement noted that improvements in data systems and oversight had already been implemented as a direct result of the case.
