Abuse of Power: Connecting Robert Kennedy's Assassination with the Murders of JFK and Dorothy Kilgallen Exposes Who Was Responsible and Why Sirhan Sirhan Deserves a New Trial

On December 15, 1985, powerful mafia don Carlos Marcello, referring to JFK's death, told a fellow Texas prison inmate, in part, that, "Yeah, I had the son of a bitch killed." This changes everything about not only the president's assassination but also reveals Marcello's complicity in the deaths of journalist Dorothy Kilgallen in 1965 and the assassination of Robert F. Kennedy.

The credible audiotaped admission by Marcello validates fifteen years of research by noted historian and bestselling author Mark Shaw in his last four books as true crime meets murder mystery in this groundbreaking historical exposé where the connection between three of America's most puzzling deaths is exposed for the first time.

To that end, Shaw’s evidence, which may be covered up by a recent governmental investigation even though those involved are aware of Marcello’s confession, points to his use of three patsies, Lee Harvey Oswald, Kilgallen's romantic interest Ron Pataky turned Judas, and Sirhan who served as decoys.

Abuse of Power will stand the test of time as the definitive source for those seeking logical, primary source accounts of the life and times, and the deaths of three prominent American icons.
