Notable Crime Cases


R v Katie Tidmarsh [2023] (Wall J)

Instructed by CPS to advise on reinstatement of proceedings after a decision made by CPS in 2013 not to prosecute a woman for the alleged killing of her adoptive baby in 2012. Experts in 12 areas of clinical medicine and pathology were instructed and advice given that the suspect should be charged with murder and associated sub-lethal violence. Wall J refused an application to stay the trial as being an abuse of process. The defendant was successfully prosecuted for murder and inflicting grievous bodily harm.


R v Leila Borrington [2023] (Nicklin J)

Instructed by CPS to advise on charge in a case concerning the death from closed head injury of a 3-year-old boy with autism, one feature of which was self-injurious behaviour including head-banging. Experts in 9 areas of clinical medicine and pathology were instructed. The defendant was successfully prosecuted for manslaughter and inflicting grievous bodily harm on the same child on two previous occasions.


R v Paris Mayo [2023] (Garnham J)

Instructed by CPS to advise on charge in a case concerning the death of a newborn baby born to a 15-year- old girl in secret following a concealed pregnancy. Experts in 10 areas of clinical medicine and pathology were instructed, along with two experts in forensic and adolescent psychiatry. The defendant was successfully prosecuted for murder, the jury rejecting the partial defence of infanticide.


R v Laura Heath [2022] (Dove J)

Instructed by CPS to advise on charge in a case concerning the death of a 7-year-old from uncontrolled asthma. Experts in respiratory medicine and pathology were instructed. The child’s mother was charged and convicted of gross negligence manslaughter and child cruelty.


R v Emma Tustin & Thomas Hughes [2021] (Wall J)

Successful prosecution of two defendants for the shocking abuse and killing of 6-year-old Arthur Labinjo- Hughes during lockdown. Emma Tustin was convicted of murder and child cruelty. Thomas Hughes was convicted of manslaughter and child cruelty. The Judge described the evidence as “distressing and disturbing” with the protracted cruelty amounting to “unimaginable suffering”. In an unprecedented gesture, the Secretary of State for Education publicly acknowledged Jonas’ outstanding work in this troubling case in a formal statement to the House of Commons.


R v Haroldas Bugaila [2021] (Baker J)

Instructed by CPS to advise on charge in a case concerning the death of a 2-month-old baby and life- changing brain damage sustained by his surviving twin.
