Robert F. Kennedy assassination conspiracy theories
The conspiracy theories relating to the assassination of Robert F. Kennedy, a United States Senator and brother of assassinated President John F. Kennedy, relate to non-standard accounts of the assassination that took place shortly after midnight on June 5, 1968, in Los Angeles, California. Robert F. Kennedy was assassinated during celebrations of his successful campaign in the Californian primary elections while seeking the Democratic nomination for U.S. president.
The perpetrator was a 24-year-old Palestinian immigrant named Sirhan Sirhan, who remains incarcerated for the crime as of 2015[update]. However, as with his brother's death, Robert Kennedy's assassination and the circumstances surrounding it have spawned various conspiracy theories, particularly regarding the existence of a supposed second gunman. Such theories have also centered on the alleged presence of a woman wearing a polka dot dress claiming responsibility for the crime and the purported involvement of the Central Intelligence Agency. Many of these theories were examined during an investigation ordered by the United States Senate, and were judged to be erroneous by the Federal Bureau of Investigation, which investigated on the Senate's behalf.
The location of Kennedy's wounds suggested that his assailant had stood behind him, but some witnesses said that Sirhan faced west as Kennedy moved through the pantry facing east. This has led to the suggestion that a second gunman actually fired the fatal shot, a possibility supported by coroner Thomas Noguchi who stated that the fatal shot was behind Kennedy's right ear and had been fired at a distance of approximately one inch. Other witnesses, though, said that as Sirhan approached, Kennedy was turning to his left shaking hands, facing north and so exposing his right side. As recently as 2008, eyewitness John Pilger asserted his belief that there must have been a second gunman. During a re-examination of the case in 1975, the Los Angeles Superior Court ordered expert examination of the possibility of a second gun having been used, and the conclusion of the experts was that there was little or no evidence to support this theory.
In 2007, analysis of an audio recording  of the shooting made that night by freelance reporter Stanislaw Pruszynski appeared to indicate, according to forensic expert Philip van Praag, that at least thirteen shots were fired even though Sirhan's gun held only eight rounds. Van Praag alleged that the recording also revealed at least two cases where the timing between shots was shorter than humanly possible. Van Praag also alleged that an analysis of the Pruszynski tape reveals the firing of more than eight shots was independently corroborated by forensic audio specialists Wes Dooley and Paul Pegas of Audio Engineering Associates in Pasadena, California, forensic audio and ballistics expert Eddy B. Brixen in Copenhagen, Denmark, and audio specialist Phil Spencer Whitehead of the Georgia Institute of Technology in Atlanta, Georgia. Some other acoustic experts, through their own independent analysis, have stated that they believe no more than eight shots are recorded on the audio tape.
On November 26, 2011, Sirhan's defense attorneys William F. Pepper and Laurie Dusek filed a 62 page brief in Los Angeles federal court which asserts that a bullet used as evidence to convict Sirhan was switched with another bullet at the crime scene. The brief claims that this was done because the bullet taken from Kennedy's neck did not match Sirhan's gun. Pepper and Dusek claim that the new evidence presented in their brief is sufficient to prove Sirhan innocent under the law.
The security guard
Thane Eugene Cesar has been consistently cited as the most likely candidate for a second gunman in the RFK assassination. Cesar had been employed by Ace Guard Service to protect Robert Kennedy at the Ambassador Hotel. This was not his full-time job. During the day he worked as a maintenance plumber at the Lockheed Aircraft plant in Burbank, a job that required a security clearance from the Department of Defense. He worked there from 1966 until losing his job in 1971. Dan Moldea wrote that Cesar began working at Hughes in 1973, a job he held for seven years and a position Cesar said required the second highest clearance level at the plant.
When interviewed, Cesar stated that he did draw a gun at the scene of the shooting but insisted the weapon was a Rohm .38, not a .22, the caliber of the bullets found in Kennedy. He also claimed that he got knocked down after the first shot and did not get the opportunity to fire his gun. The LAPD, which interviewed Cesar shortly after the shooting, did not regard Cesar as a suspect and did not ask to see his gun.
Cesar stated that he did own a .22-caliber Harrington & Richardson pistol, and he showed it to LAPD sergeant P. E. O'Steen on June 24, 1968. When the LAPD interviewed Cesar three years later, however, he claimed that he had sold the gun before the assassination to a man named Jim Yoder. William W. Turner tracked down Yoder in October 1972. Yoder still had the receipt for the H & R pistol, which was dated September 6, 1968, and bore Cesar's signature. Cesar therefore had sold the pistol to Yoder three months after Kennedy's assassination despite Cesar's claim in 1971 that he had sold the weapon months before the murder. Author Dan Moldea wrote that Cesar submitted years later to a polygraph examination performed by Edward Gelb, former president and executive director of the American Polygraph Association. Moldea reported that Cesar denied any involvement in Kennedy's assassination and passed the test with flying colors.
Manchurian candidate hypothesis
Another conspiracy theory relates to a Manchurian candidate hypothesis, that Sirhan was psychologically programmed by persons unknown to commit the murder, that he was not aware of his actions at the time, and that his mind was "wiped" in the aftermath by the conspirators so he would have no memory of the event nor of the persons who "programmed" him. This theory was supported by psychologist and hypnosis expert Dr. Eduard Simson-Kallas after 35 hours of work with Sirhan in San Quentin prison in 1969 after his conviction. Sirhan claimed then, and has continued to claim since, to have no memory of the assassination or its aftermath.
The woman in the polka-dot dress
Some witnesses stated that they observed a woman in a polka dot dress in various location throughout the Ambassador Hotel before and after the assassination. One witness, Kennedy campaign worker Sandra Serrano, reported that around 11:30 pm she was sitting outside on a stairway that led to the Embassy Ballroom when a woman and two men, one whom she later stated was Sirhan, walked past her up the stairs. Serrano said that around 30 minutes later she heard noises that sounded like the back-fire of an automobile, then saw the woman and one of the men running from the scene. She stated that the woman exclaimed, "We shot him, we shot him!". According to Serrano, when she asked the woman to whom she was referred, the woman said "Senator Kennedy." For conspiracy advocates, Serrano's account has persisted as proof of a conspiracy.
Another witness, Evan Freed, also saw the girl in the polka dot dress. This report was connected by alternative theorists such as with another report of a girl wearing a polka dot dress who was supposedly seen with Sirhan at various times during the evening, including in the kitchen where the assassination took place. Serrano stated that preceding her supposed encounter with the polka-dot dress girl, she heard a series of shots that sounded like a car backfiring. However, following this claim, LAPD criminologist DeWayne Wolfer conducted tests to determine if Serrano could have heard the shots from her location. He found that there would have been a change in sound level of 1/2 decibel at Serrano's location resulting from a shot being fired in the kitchen of the hotel, and concluded that she could therefore not have heard the shots as she claimed. Additionally, Kranz commented in his report that Serrano admitted to fabricating the story following further interviews with investigating officers and that he was unable to find evidence to corroborate any aspect of the original account.
In November 2006, BBC Television's Newsnight aired a twelve-minute screening of Shane O'Sullivan's documentary RFK Must Die. O'Sullivan stated that while researching a screenplay based on the Manchurian candidate theory for the assassination of Robert Kennedy, he "uncovered new video and photographic evidence suggesting that three senior CIA operatives were behind the killing". He claimed that three men seen in video and photographs of the Ambassador Hotel immediately before and after the assassination were positively identified as CIA operatives David Sánchez Morales, Gordon Campbell, and George Joannides.
Several people who had known Morales, including family members, were adamant that he was not the man who O'Sullivan said was Morales. After O'Sullivan published his book, assassination researchers Jefferson Morley and David Talbot also discovered that Campbell had died of a heart attack in 1962, six years prior to the assassination of Kennedy. In response, O'Sullivan stated that the man on the video may have used Campbell's name as an alias. He then took his identifications to the Los Angeles Police Department whose files showed the men he identified as Campbell and Joannides to be Michael Roman and Frank Owens, two Bulova sales managers attending the company's convention in the Ambassador. O'Sullivan stood by his allegations stating that the Bulova watch company was a "well-known CIA cover".
