Speedboat killer Jack Shepherd is due to be released from prison in January 2029, after Isleworth Crown Court confirmed his latest 20-month sentence for attacking his girlfriend will be served concurrently with his existing term.

Judge Martin Edmunds KC explained that the law did not allow him to add any further time to the sentence Shepherd was already serving following his recall to prison, according to reports from the BBC and other media.

Shepherd, who is 38—we previously reported his age as 39—pleaded guilty in July to two counts of assault occasioning actual bodily harm and one count of criminal damage. Alongside the 20-month custodial term, he was given an extended licence period of four years.

The court heard that Shepherd began dating the victim, a woman in her 50s referred to as AB, after being released on licence in January 2024. In February 2025, during an argument, he pinned her down and punched her repeatedly, causing bruising to her arm and leg.

The second assault occurred in June 2025 following a row over dinner. After the victim remarked that Shepherd had burned a pizza, he struck her on the left breast with a pair of hot barbecue tongs, leaving a permanent scar. These incidents triggered his recall to prison in September.

Mitigating for Shepherd, who appeared via videolink from HMP Swaleside in Kent, defence counsel George Payne said his client was "genuinely very ashamed" and that his behaviour was driven by a long-standing alcohol abuse problem. Judge Edmunds dismissed this mitigation, stating he had "no faith" in Shepherd's remorse and remarking that his pattern was to commit offences, apologise, and produce prepared statements seeking to shift the blame.

A victim personal statement read to the court detailed the lasting physical and emotional trauma AB suffered, including scarring, severe anxiety, and a loss of personal safety and friendships, aggravated by Shepherd's public notoriety.

Shepherd was originally jailed for six years and six months—previously reported as six years—for manslaughter by gross negligence after 24-year-old Charlotte Brown died when his speedboat overturned on the River Thames in December 2015. After fleeing to Georgia, he was extradited back to the UK and subsequently received an additional four-year sentence in 2019 for striking a hotel barman with a vodka bottle in Devon.
