Robert Smith KC and Tom Storey successfully prosecute baby-shaking murder trial at Sheffield Crown Court.

30/01/2023

On 30th January 2023, Leon Matthias was convicted of the murder of his 9 week-old son, Hunter, following a trial before Mrs Justice Lambert at Sheffield Crown Court which lasted for three months .

Robert Smith KC and Tom Storey prosecuted this complicated case which involved the calling of multiple expert witnesses in order to prove the cause of Hunter’s death.

The jury found by their verdict that Hunter had been shaken and/or thrown against a hard surface by his father in a moment of frustration, causing multiple severe injuries to his brain and eyes, bruising to his scalp and fractures to the bones of his leg.  The defence at trial involved a challenge to virtually every aspect of the medical evidence; several defence expert witnesses from other jurisdictions were called in an ultimately unsuccessful attempt to cast doubt on the opinions of the experienced mainstream medical practitioners called on behalf of the prosecution.

The defendant was sentenced on 2nd February 2023 to life imprisonment.  Mrs Justice Lambert ordered that he should serve a minimum term of 16 years before his case was eligible for consideration by the Parole Board.
