SUMMARY

On Christmas Eve 2023 in Llandaff, Cardiff, 23-year-old William Bush was brutally murdered by his childhood friend Dylan Thomas. Thomas stabbed Bush 37 times, including 21 wounds to the neck, in a frenzied attack at the home they shared.

The night before the killing, Thomas stayed at his grandmother’s home in Rhoose before returning to Llandaff, claiming he needed to check on his dog. Evidence later revealed he had searched online for “anatomy of the neck” before the attack.

At trial, Thomas admitted manslaughter under diminished responsibility but denied murder. In November 2024, a jury found him guilty of murder. He was sentenced in January 2025 to life imprisonment with a minimum term of 19 years.

William’s family described him as a “loyal, funny, and caring” young man with a promising future — a life cut short by senseless violence that left a community reeling and a family shattered.
