Jack Shepherd, 38, has been sentenced to 20 months in jail with an additional four years on extended license for assaulting his girlfriend in February and June 2025. The assaults included hitting her chest with hot barbecue tongs, which caused a permanent scar. Previously jailed for manslaughter after the fatal speedboat crash that killed Charlotte Brown in 2015, Shepherd also served time for an attack on a barman in 2018. His most recent sentence will run concurrently with his ongoing manslaughter sentence, and he is expected to be released in January 2029.

Why this leaning score
This article does not take a side on a contested political
question, so it has no leaning score. That is an
answer rather than a gap: a match report or a rescue can be warmly
or critically written without being left or right, and scoring it
anyway is how approval of a subject gets recorded as a political
position.
