This is an uncorrected and unedited transcript of the "20/20" broadcast which first aired June 14, 2000.
Good evening. And welcome to 20/20 WEDNESDAY. Diane and Charlie are off. Tonight, we are devoting most of this hour to a special report. Explosive new developments in a continuing investigation. Three murders that have never been solved. They occurred during one of this country's darkest chapters when bigotry bred violence and the law looked the other way. Two black teen-agers offered a ride and then killed in cold blood. An elderly black farmhand shot to death at close range. Decades have passed and their stories have faded. But now, our investigation has brought these cases back to life and just maybe justice will prevail at last.
(VO) THOMAS MOORE visits the grave of his brother Charles who was murdered along with a friend 36 years ago. There was evidence, informants, even two arrests, but nobody was ever convicted of murder.
(OC) What kind of men would do that to someone like your brother?
Hate. Ignorant. Not being able to accept a person as who they are.
(VO) He owns only a single image of his younger brother, a college student. Of the other victim, Henry Dee, there isn't even a photo. Thomas has been plagued by the murders. When he returned from Vietnam, he earned a second college degree and dedicated it in the name of his brother and in the name of justice.
I will pursue this as far as I can until I die trying to find out who did this and why.
(VO) It was May 2nd, 1964, Charles Moore and Henry Dee, both 19, were offered a ride in Meadville, Mississippi, taken deep into the nearby Homochitto National Forest and beaten, their bodies dumped into the Mississippi River. Two alleged Klansman, James Ford Seale and Charles Marcus Edwards were arrested.
When they made the arrests on those people, I didn't have any doubt in my mind that that's the one that done it. I didn't.
(VO) J.T. Robinson was police chief in nearby Natchez.
(OC) You think that Charles Marcus Edwards killed those two men?
I think he was part -- he was with James Seale and they done it.
(VO) Both suspects were soon freed. An FBI investigation petered out. And as we learned in a surprising response to our inquiry, the entire FBI file on the case was destroyed in 1977 or so they thought. Until this headline appeared recently in the Jackson-Clarion Ledger over a story by reporter Jerry Mitchell.
And so then I was able to go back to the FBI and go, 'Wait a minute, you know, those files weren't destroyed, here are copies.'
(VO) From a different source, 20/20 obtained an unredacted copy of the FBI file. Nearly a thousand pages of reports, notes, diagrams, maps and photographs. But most revealing was the fact that the FBI had one very important informant. An informant who remained anonymous, refusing to testify in open court for fear of retaliation from the Klan. Retired FBI assistant director Jim Ingram was at the time a special agent assigned to the case. He remembers the informant code name JN-30.
JN-30 was so important to the FBI that the agents themselves did not know his identity, except two agents that worked or handled him.
