Man with severe learning difficulties has murder conviction quashed after 34-year fight

Oliver Campbell was convicted of murder in 1991 for the killing of a shopkeeper. Campbell suffered a brain injury as a baby and was jailed for life. However, a recent ruling by three judges deemed Campbell's 1990 conviction "unsafe". Campbell has maintained his innocence throughout the years, confessing to the crimes during police interviews, but his lawyer has suggested that the confessions were coerced. Campbell's conviction was based partly on these admissions, which he now claims were obtained unfairly.
