Despite there being no evidence to substantiate his claims, the killer’s stepmother told The Daily Mail: “I heard Jack had handed himself in. I will probably get my head bitten off for saying this, but I am not happy about this at all.
“She hit a log and they are blaming him for everything. So I am not very happy about it at all. But I do feel very sorry for her parents for what happened.”
Ms Brown’s father Graham rubbished both Shepherd and his stepmother’s claims, saying the speedboat killer was a “proven liar”.
Shepherd, originally from Exeter, went on the run before his trial at the Old Bailey and jurors found him guilty of manslaughter by gross negligence.
He was sentenced to six years imprisonment, but remained at liberty.
That was until Wednesday when, wearing a long beard and a smile, Shepherd walked into a Georgian police station flanked by lawyers and gave an interview proclaiming his innocence.
The CPS said prosecutors are currently “consulting with the authorities in Georgia to progress our extradition request”.
Tariel Kakabadze, Shepherd’s lawyer in Georgia, said he may still fight his extradition to the UK, where his legal team has been granted leave to appeal his conviction.
