Jackson served as treasurer of the Natchez, Mississippi branch of the NAACP (National Association for the Advancement of Colored People) until his assassination by a car bomb, which was placed on the frame of his truck under the driver-side seat.
The scene of his death was six blocks away from the site where he was employed,[1] at Armstrong Rubber and Tire Company.
The culprit was never found, and while the FBI suspected the involvement of the Silver Dollar Group, an offshoot of the Ku Klux Klan, there was no investigation that came up with a conclusion or a culprit, despite the ten thousand pages of FBI documentation and evidence.
After receiving a promotion at Armstrong Rubber and Tire Company, Metacalfe got into his car and started the ignition, triggering a similar explosion which severely injured him.
