In 2019, the Offender Database recorded that Jonathan Garner, 26, was jailed for life for the murder of his partner’s 23-month-old daughter, Mia Gregson. On appearing at Sheffield Crown Court, the defendant—of Gipsyville, West Hull—was ordered to serve a minimum of 20 years behind bars. It was reported that the child’s mother, Samantha Gregson, 26, was also convicted and jailed for four years for causing or allowing the death of her daughter. The path to justice for Mia took nearly six years following the fatal incident on 13 February 2014.
The investigation established that Mia was subjected to weeks of physical and verbal abuse before she was smothered to death. Humberside Police reported that the toddler suffered bruising to her head and face, a broken ankle caused by twisting, and likely cigarette burns. The prosecution reported that Garner deliberately smothered the child because she was crying, leading to cardiac arrest and irreversible brain damage. The investigation established that Samantha Gregson was “awake and present” in the room when her daughter was killed but failed to intervene.
Judicial Findings and Investigative Detail
The court reported that Gregson had been specifically warned by social services about Garner’s violent history and the risk he posed to children, yet she chose to move in with him. Sheffield Crown Court heard that Mia had been living in an environment of constant threats and shouting in the weeks leading up to her death. The investigation established that although an initial probe in 2014 was inconclusive, new information came to light in 2015 that allowed police to bring murder charges against the couple.
Justice Goss noted that it was “highly likely” the day Mia died was not the first time she had been smothered. For his actions in Hull, Garner was found guilty of murder, while Gregson was found guilty of failing to protect her child despite knowing of the abuse since mid-January 2014. The judge acknowledged that while Gregson was herself in an abusive relationship with Garner, she had failed to take multiple opportunities to seek help for her daughter.

Monitoring and Public Protection
Garner is managed as a Category A high-risk violent offender within the prison estate. Due to the nature of his conduct in Hull, which involved the systematic torture and eventual murder of a defenceless toddler, his management is a maximum priority. Authorities state that Gregson, who was pregnant with Garner’s child at the time of the murder, went on to have two more children in the years before her conviction, which raised significant concerns for social services regarding her ability to protect minors.
As a convicted murderer, Garner’s details are permanently logged on national criminal databases. Authorities state that the “vile” nature of the injuries inflicted on Mia—including the twisting of her ankle and the smothering—requires that Garner remain under the most stringent security classifications. Any future consideration for parole after his 20-year minimum term will be subject to intense scrutiny by the Parole Board to assess the ongoing risk he poses to women and children.
