The trial of a reputed Ku Klux Klansman (search) in the 1964 slayings of three civil rights workers was postponed Thursday to April 18, in part to give the defense time to review tips received as part of the reopened investigation.

Edgar Ray Killen (search), an 80-year-old part-time preacher and former lumber mill operator, had been scheduled to go on trial March 28 in the killings of James Chaney (search), Michael Schwerner (search) and Andrew Goodman (search), volunteers helping blacks register to vote.

Defense attorney Mitch Moran asked for time to look into information received via a tip line that was set up by a church organization after prosecutors reopened the case.

Circuit Judge Marcus Gordon said the three-week delay would also allow more time to prepare a questionnaire for prospective jurors.
