The brother of slain civil rights worker James Chaney said Tuesday that he has felt anger and frustration for the past 40 years.
No one has ever been prosecuted for the 1964 murders of Chaney, a Meridian native, and Andrew Goodman and Mickey Schwerner of New York.
Each was involved in voter registration and other civil rights work during freedom summer 1964 in Mississippi.
At a news conference Tuesday in Washington, D.C., Ben Chaney announced a series of events that will mark the 40th anniversary of the tragedy.
A 20-bus caravan will leave New York on June 9 and later include a memorial service in Neshoba County.
Along the way, participants will do door-to-door voter registration, as others did during freedom summer 1964.
