What was not contested throughout the trial, however, was the severity of the injuries inflicted on Isabella.

Bone pathologist Prof Anthony Freemont said he had never before seen such a degree of pelvic injury in a child in his 40-year career.

It was also said that the toddler had died with injuries usually seen in “high-velocity traffic accidents” or when “being kicked by a horse”.

But, even after she died, Gleason-Mitchell and Jeff opted against reporting it to the police, instead choosing to pretend she was still alive.

They wheeled her dead body around Ipswich in a pushchair while they shopped, drank and took cocaine.

Toxicology reports even revealed traces of the drug, as well as cannabis, in Isabella’s body, understood to be ingested second-hand as a result of the couple’s own drug use.

The alarm was only raised when, on 29 June, Gleason-Mitchell admitted to friend Joanne Gardner online that Isabella had been dead in her pushchair for around three days.

She said she had not contacted the authorities out of fear she would “get done” because of the bruising on her daughter’s body.
