A mother who killed her baby daughter with heat from a hairdryer after a night out partying has been jailed for just six years. Courtney Gartshore, 28, used the appliance to subject three-month-old Dahlia-Rose Gartshore to 'significant and sustained heat' at an address in Peterhead, Aberdeenshire in September 2023. Dahlia-Rose suffered burns to approximately 18 per cent of her body surface – particularly to her head, neck, upper body and one of her arms.The injuries were so severe that a paramedic thought her body was decomposing and experts said they had never encountered a similar case.Gartshore was convicted of culpable homicide following a trial at the High Court in Aberdeen in July.Sentencing her at the High Court in Edinburgh today, judge Simon Collins KC ruled that while Gartshore had not intended to harm or kill her baby, she was culpable in the 'highest degree' of carelessness.He added that it 'should have been obvious' that Dahlia-Rose was in 'severe distress and pain'.'You will have to live the rest of your life with the knowledge that you were responsible for her death,' he said. 'This was a gross breach of the most basic duty as a parent.'Judge Collins said Dahlia-Rose's likely cause of death was hyperthermia and heat stroke.

'The death of any child is particularly harrowing, but a child's death at the hands of a parent is incredibly disturbing. Gartshore pictured outside the trial in Aberdeen.
