Description
Abuse of Power includes updated Marilyn Monroe murder probe, and 2025 JFK and RFK assassination records release analysis.
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 shocking audio-taped confession, based on the motive of revenge per FBI files released in early 2025, 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 three years later.
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 expose where the connection between three of America's most puzzling deaths is exposed for the first time. Shaw reveals a common sense account regarding what really happened when JFK, Kilgallen, and RFK died with the latter involving an apparent miscarriage of justice where Sirhan Sirhan may have been wrongfully convicted.
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. Each was caught in the snare of this deadly mastermind when he eliminated JFK, Kilgallen, the most credible reporter to have investigated JFK's death, and RFK while J. Edgar Hoover hid the truth by protecting Marcello from any possible investigation. Regarding Sirhan, the new evidence proves that he deserves a retrial, one that could rock the nation's perception of historical truth.
Without question, 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.
