Martin Luther King's assassination led to riots in more than 100 US cities. James Earl Ray was convicted of his murder and sentenced to 99 years in prison. But he later retracted his confession and said he had been only a minor player in a conspiracy. However, his appeals for a new trial were rejected and he died in prison in 1998. Ray was supported by some members of Martin Luther King's family who believed the US Government may have been involved in Dr King's death. Their case was strengthened in December 1999 when a jury in a wrongful death case brought by the King family, decided the civil rights leader was the victim of a murder conspiracy.
