Speedboat Killer Jack Shepherd Pleads Guilty to Violently Assaulting Girlfriend, Used Tongs

The 2015 River Thames incident involved Shepherd's champagne-fuelled date on a speedboat that capsized after clipping a partially submerged tree trunk, with the boat described as defective and Charlotte Brown dying as a result.
Shepherd was convicted of manslaughter by gross negligence in his absence after fleeing to Georgia to avoid the Old Bailey trial; he was later extradited back to the UK to serve the sentence.
He was released on licence in January 2024 but was recalled to prison for breaching that licence following an alleged act of violence toward a girlfriend, with recall reported in the following months.
In Isleworth Crown Court, Shepherd pleaded guilty to two counts of assault occasioning actual bodily harm and criminal damage, with prosecutors dropping two other charges (controlling or coercive behaviour and intentional suffocation).
The assaults occurred in February 2025 and June 2025, including an incident in which barbecue tongs were used against the girlfriend; Shepherd appeared via videolink from HMP Swaleside with a sentencing hearing set for September 4.
Jack Shepherd, known as the "speedboat killer," has pleaded guilty to violently assaulting a new girlfriend — including hitting her with barbecue tongs. The 38-year-old appeared via video link from HMP Swaleside at Isleworth Crown Court to admit two counts of assault occasioning actual bodily harm and one count of criminal damage, according to Metro and The Mirror.
Shepherd was already back behind bars after being recalled to prison for breaching the licence terms of his 10-year sentence for manslaughter. A sentencing hearing for the new offences is set for September 4, Devon Live reports.
The assaults took place in February 2025 and June 2025. In one incident, Shepherd struck his girlfriend on the chest with a set of barbecue tongs, Yahoo News reported. He also punched her and damaged property during the attacks. Prosecutors dropped two additional charges — controlling or coercive behaviour and intentional suffocation — which will remain on file.
Shepherd admitted the offences via video link. He did not appear in person. Prosecutors told the court the case continues to develop as more details emerge, according to AOL News.
Shepherd's notoriety began on the River Thames in 2015. He took Charlotte Brown, then 24, on a champagne-fuelled speedboat date he had arranged on Tinder. The boat capsized after clipping a partially submerged tree trunk. The vessel was later found to be defective. Brown drowned. Shepherd earned the tabloid nickname "Captain Jack" for his role that night.
He was convicted of manslaughter by gross negligence at the Old Bailey — but was not there to hear it. Shepherd had fled to Georgia to avoid the trial. He was later extradited back to the UK and began serving a 10-year sentence, The Mirror reported.
Shepherd was released on licence in January 2024. Licence release means a prisoner is freed early under strict conditions. He was recalled to prison by September of that year after allegedly committing an act of violence toward a girlfriend — a breach of those conditions, Devon Live reported.
The February and June 2025 assaults were committed while he was back in custody awaiting resolution of those new allegations. His pattern of offending has raised fresh questions about risk management for prisoners released on licence after violent convictions.
Shepherd faces sentencing on September 4 at Isleworth Crown Court. The two assault charges he admitted to carry a maximum of five years each. Prosecutors indicated that further details may still emerge before that date, AOL News reported. He remains held at HMP Swaleside on the Isle of Sheppey in Kent.
