Una Crown was an 86-year-old woman who was murdered in her home in Wisbech in Cambridgeshire, England, in 2013. Her death was initially treated as unsuspicious, but a post-mortem concluded that she had died from stab wounds to her neck and chest. At least one suspect was arrested but no individuals were charged. The brutality of the case and admission of police failure in the murder investigation brought national attention to the case. The case remains unsolved.
