The Justice Department says an investigation into the killings of three civil rights workers in Mississippi in 1964 will continue despite the death of a key suspect. Billy Wayne Posey died Thursday at the age of 73.
Federal investigators say they were looking into his possible involvement in the June 1964 killings of James Chaney, Andrew Goodman and Michael Schwerener -- who had come to the state to register black voters.
The Justice Department says the cold-case investigation will continue. Federal authorities are assisting state investigators who could bring state charges.
The slayings shocked the nation, helped spur passage of the landmark Civil Rights Act and were dramatized in the 1988 movie "Mississippi Burning."
