UK knife murders linked to TikTok spark documentaries

In 2023, 17‑year‑old Charlie Cosser was stabbed to death at a summer party in West Sussex, England. His father, Martin Cosser, later turned to TikTok to share his grief and campaign against knife violence, a story now featured in a German RTL+ documentary.

Separately, 62‑year‑old veteran Stuart Crocker was found with 26 stab wounds in his Andover home. The case, involving his younger partner Winter Swan Miller, who had built a TikTok following, became the focus of the Prime Video series “Britain’s TikTok Murder.” Both incidents highlight how social‑media platforms intersect with violent crime in the United Kingdom.
