It didn't take as long as I thought it might to put the info together.
   In December 1993, Lloyd Jowers appeared on ABC's Prime Time Live and
   related the details of an alleged conspiracy involving the Mafia and
   the U.S. government to kill King. According to Jowers, James Earl Ray
   was a scapegoat, and was not responsible for the assassination. Jowers
   said that he hired Memphis police Lieutenant Earl Clark to fire the
   fatal shot. The existence of such a conspiracy, and Jowers'
   involvement, was supported in the verdict of a 1998 court case which
   was brought against Jowers by the King family. The allegations and the
   finding of the Memphis jury were later rejected by the United States
   Department of Justice in 2000.
   In 1998, the King family filed a wrongful death lawsuit against Jowers
   and "other unknown co-conspirators" for the murder of King. The King
   family was represented by attorney William Pepper, who had previously
   served as the attorney of James Earl Ray, King's formerly accused
   assassin. After four weeks of testimony and over 70 witnesses in a
   civil trial in Memphis, Tennessee, twelve jurors reached a unanimous
   verdict on December 8, 1999 after about an hour of deliberations that
   Dr. Martin Luther King, Jr. was assassinated as a result of a
   conspiracy which also involved "others, including governmental
   agencies."
   Mrs. Coretta Scott King commented on the verdict, saying, “There is
   abundant evidence of a major high level conspiracy in the assassination
   of my husband, Martin Luther King, Jr. And the civil court's unanimous
   verdict has validated our belief. I wholeheartedly applaud the verdict
   of the jury and I feel that justice has been well served in their
   deliberations. This verdict is not only a great victory for my family,
   but also a great victory for America."
