A man named Peter Sullivan, who spent nearly 40 years in prison for the 1986 murder of florist Diane Sindall, has had his conviction quashed, marking the longest miscarriage of justice in British history. The Court of Appeal ruled in his favor after new DNA evidence indicated he did not commit the crime, with the Crown Prosecution Service acknowledging the findings undermined their original case. Sullivan, who maintained his innocence and raised concerns over his legal representation during police interviews, was finally freed after a lengthy legal battle.
