IPSWICH teenager - and Britain’s youngest female double murderer - Lorraine Thorpe today lost her appeal against her conviction for killing her father.

Thorpe, formerly of Clapgate Lane, who is 17 in two days time, was found guilty of the murders of her dad, Desmond, at Limerick Close, Ipswich, and Rosalyn Hunt, who she tortured and killed.

Ms Hunt’s body was found at her home in Victoria Street, Ipswich. Mr Thorpe and Ms Hunt’s bodies were found within 24 hours of each other in the summer of 2009.

Thorpe and her alleged boyfriend Paul Clarke, 42, were found guilty in August last year of the murders following a trial at Ipswich Crown Court.

Both received life jail sentences. Thorpe’s sentencing took place at the Old Bailey in September last year.

Today the pair returned to court, where their lawyers claimed their convictions for the murder of Mr Thorpe were “unsafe” and should be overturned.

After reviewing evidence from the case, three senior judges sitting at London’s Court of Appeal rejected their arguments and upheld the convictions.
