The 1960s Ku Klux Klan leader who was convicted over the infamous deaths of three civil rights workers in MS has died.
Killen, 92, died on Thursday in the state penitentiary in Drew, Miss. The case was reopened decades later, and Killen was convicted in 2005 of three counts of manslaughter.
The slayings of James Chaney, Andrew Goodman and Michael Schwerner in Philadelphia, Mississippi, on June 21, 1964, at the hands of the Klan, local law enforcement officers and others was one of the most shocking and galvanizing moments of the USA civil rights movement.
The slayings were among the most notorious of the civil rights era and were the subject of the 1988 movie "Mississippi Burning".

After their release from the county jail in Philadelphia, a Ku Klux Klan mob tailed their vehicle, forced it off the road and shot them to death.
Killen's cause of death was not released, but officials say no foul play is suspected.
Their bodies were found buried in a red-clay dam in rural Neshoba County.
In June 2016, the state of MS finally officially closed the case.

After federal intervention, 18 men were trialled in 1967 on civil rights violation charges. None served more than six years in prison.
He was a farmer, preacher and sawmill operator in MS during the height of the civil rights movement of the 1960s.
Killen, a former Baptist preacher, was accused of orchestrating the killings, but his trial ended in a hung jury after a juror said she could not convict a preacher.
The three men had been taken into custody on a speeding charge and while they were detained, Killen assembled the mob that later would chase them down and kill them, prosecutors said at his 2005 trial.
Almost 40 years later, he was retried after the state reopened the murder investigations.More news: Supreme Court will weigh letting states collect tax on e-commerce sales
