The mother of a woman who died in a speedboat crash has issued a direct appeal to her daughter's fugitive killer to return and face justice.

Jack Shepherd has been at large since July last year when he was convicted over the death of 24-year-old Charlotte Brown, who was originally from Welling.

The web designer was found guilty of manslaughter by gross negligence in his absence having fled his Old Bailey trial. His whereabouts remains a mystery to police.

On Sunday, more than three years after her daughter's death, Roz Wickens pleaded for the convicted killer to resurface.

"She was everything to me and I think about her almost every second of the day," the 53-year-old from Clacton-on-Sea, Essex, told the Mail on Sunday.

"Life will never be the same without her. So please return and face the justice that was dealt to you."

Police on Friday conceded they have know clue where in the world the 31-year-old is, and said he may be using bank accounts belonging to friends to fund his life on the run.

Ms Wickens added: "I want to tell anyone who is helping him, 'Think about what you are doing, and do the right thing by talking to the police.'

"I mean, if someone thinks they are not guilty, why would they run away to another country and hide?"

Shepherd, originally from Exeter, was sentenced to six years in jail over the death of Ms Brown, known to her friends as Charli.

She died after the shabby speedboat, which the court heard Shepherd bought from Gumtree to "pull women", capsized in central London's icy waters in December 2015.

While on the run, Shepherd has contacted his lawyers to appeal against the conviction.
