SPEEDBOAT killer Jack Shepherd is back behind bars again – this time after stabbing his partner in the chest with hot BBQ tongs.

The 38-year-old – who married and moved to an isolated cottage in Llangattock Lingoed between Monmouth and Abergavenny just weeks after the December 2015 River Thames death of 24-year-old Tinder date Charlotte Brown – admitted assault and criminal damage in his latest court appearance at Isleworth Crown Court.

After being jailed for six and a half years in 2018 for manslaughter, having previously gone on the run to Georgia, he was then jailed for another four years at Exeter Crown Court in 2019 for a drink-fuelled attack with a vodka bottle on a barman at a Devon hotel.

He was released on licence in January 2024, but faced recall to prison in September 2025 after he was accused of violence towards the woman, who was only named in court documents as 'X'.

Isleworth Crown Court heard Shepherd started dating her in August 2024, but in an argument in February 2025 pinned her down "punching her several times, causing bruising to her arm and top of leg".

Then in June 2025, he accused her of burning a pizza on the BBQ and "proceeded to hit her with the tongs on her left breast which caused a permanent scar".

George Payne for Shepherd told the court he was "genuinely very ashamed of his behaviour... driven by his abuse of alcohol".

But Judge Martin Edmunds, jailing him for another 20 months, said he had "sought to shift blame anywhere but yourself”.

Self-styled Casanova Shepherd was driving Charlotte Brown in a late night speedboat ride on the Thames in December 2015, when they capsized near Wandsworth Bridge and she died.

Later charged over the tragedy, the website designer then went on the run for 10 months and failed to appear at his trial.

The trial heard that his 14ft-long speedboat was defective, he drove at high speed and there were no lifejackets on the craft, which he launched late at night in the middle of winter.

Shepherd had carried out his speedboat seduction routine on a string of women, it was also revealed.

Having wined and dined Charlotte at the upmarket Shard restaurant, where he bought vodka and two bottles of wine, he then opened champagne on the boat.

But disaster happened when the boat flipped, throwing both into the freezing Thames.

Witnesses said he appeared drunk, but tests on Ms Brown's body showed she had only drunk a moderate amount.

Within weeks, Shepherd had moved to the hidden rural cottage in the Monmouthshire countryside after marrying his childhood sweetheart the day after a second police interview under caution.

They had a child together within a year of the accident, but in September 2017 he was charged with manslaughter and bailed to appear for trial at the Old Bailey in April 2018.

Shepherd failed to appear, and it later transpired that he had split from his newly-wed wife and child and gone on the run to Tbilisi, where he had been living the high life enjoying drunken nights out and ski trips.
