On the face of it Jack Grant appeared to be something of a web genius, with vast experience at companies such as Apple not to mention the directorship of his own digital business.

Yet, as has transpired with many aspects of this sorry tale, nothing was quite as it seemed.

Grant, it is understood, was actually Jack Shepherd, the speedboat killer who compounded his crime by spending ten months on the run in Georgia, accusing his victim’s father of threatening him and vowing to avoid extradition.

This latest twist means the 31-year-old could face fresh prosecution and further jail time over claims he used a false identity in a company set up before he fled the country.

Documents filed with Companies House suggest that Shepherd was operating under the pseudonym for several months in the UK as he sought work after being charged with the manslaughter by gross negligence of Charlotte Brown, 24, and his real identity was widely publicised, the Telegraph understands.

It is an offence to file false information on the register and anyone found to have knowingly done so could be jailed for up to two years.
