How does Roscoe Jones describe Mickey Schwerner?

Michael Henry "Mickey" Schwerner (November 6, 1939 – June 21, 1964), was one of three Congress of Racial Equality (CORE) field/social workers killed in Philadelphia, Mississippi, by members of the Ku Klux Klan. Schwerner and two co-workers, James Chaney and Andrew Goodman, were killed in response to their civil rights work, which included promoting voting registration among African Americans, most of whom had been disenfranchised in the state since 1890.
