Jack Shepherd, infamously known as the “speedboat killer,” has been sentenced to an additional 20 months in prison after assaulting his girlfriend with sharp barbecue tongs. The 39-year-old was found guilty of violently attacking the woman while intoxicated, including pinning her down and punching her, as well as stabbing her in the chest with the tongs.
During sentencing at Isleworth Crown Court, Judge Martin Edmunds KC highlighted Shepherd’s ongoing danger, particularly to any new partners, stating that his inability to control his drinking only increases the risk he poses. The judge described the offenses as “snapshots of inexcusable violence” and acknowledged the lasting impact on the victim.
Shepherd’s violent history began in 2018 when he was convicted of manslaughter after a tragic speedboat crash claimed the life of 24-year-old Charlotte Brown on their first date. He received a ten-year sentence, including additional time for assaulting a hotel bartender. Shepherd fled to Georgia ahead of his Old Bailey trial but was eventually extradited back to the UK to serve his sentence.
Released on license in January 2024, Shepherd quickly found himself back in trouble after new allegations of violence surfaced in September 2025. He pleaded guilty to assault charges related to his girlfriend, admitting to the attacks which left her with bruises and a permanent scar.
Prosecutor Katherine Lloyd detailed how Shepherd had started dating the victim in August 2024. Their relationship turned violent by February of the following year, culminating in the stabbing incident during a drunken evening when he repeatedly struck her with barbecue tongs after she commented on burnt pizzas.
Shepherd initially denied the violence, blaming the victim and suggesting she was unstable. However, he later apologized, attributing his behavior to alcohol abuse. His defense lawyer noted that Shepherd is currently undergoing alcoholism treatment while imprisoned and expressed remorse on his client’s behalf.
Judge Edmunds, however, was skeptical of Shepherd’s remorse, pointing to a pattern of offending followed by excuses and blame-shifting. Shepherd was sentenced to 20 months behind bars, with an extended license period that means he will remain under supervision until May 2032.
Charlotte Brown’s family continues to grieve her loss. Her father, Graham Brown, has spoken publicly about the pain of losing his daughter and the emptiness left by Shepherd’s actions. Shepherd’s case remains a stark reminder of the dangers posed by repeat violent offenders, particularly when substance abuse is involved.
