After later leaving Isabella’s body in the flat the couple headed to Ipswich town centre to visit shops, McDonald’s and a pub.
They then caught a train to the Corn Exchange pub, in Bury St Edmunds, where CCTV footage captured them swigging drinks and going about life as “normal”.
“As a parent I just couldn’t fathom what we could see on the CCTV cameras, in no way did they appear to be showing any grief or emotion,” added Det Ch Insp Powell.
“It was disgusting. Their actions and their reactions at that time I still struggle with today – there was very little emotion.”
Then, during the early hours of 1 July, they were both arrested, with bodycam footage showing Jeff claiming: “I never murdered her.”
But the court heard how the toddler was subjected to sustained violent attacks borne out of Jeff’s “evil temper” and frustration over her struggles with potty training.
Bone pathologist Prof Anthony Freemont told the trial he had never before seen such a severe pelvic injury in a child in his 40-year career.
Jeff would kick and stamp on the toddler and punish her with cold showers, all while her mother “stood by and did nothing”.
It was also said how the couple had previously been in a relationship in 2019, during which Gleason-Mitchell’s family said she had “changed” and drank more.
Gleason-Mitchell acknowledged she “didn’t do anything to protect” her daughter from Jeff but “thought it was just a phase he was going through”.
