Ruby was arrested immediately after shooting Oswald, and he told several witnesses that he had been distraught over President Kennedy's death and had helped the city of Dallas "redeem" itself in the eyes of the public, and that his motive for killing Oswald was "saving Mrs. Kennedy the discomfiture of coming back to trial". He also claimed he shot Oswald on the spur of the moment when the opportunity presented itself, without considering any reason for doing so. Ruby told the FBI he was "in mourning" Friday and Saturday. He said he cried when he heard the President was shot, "cried a great deal" Saturday afternoon and was depressed Saturday night. He explained that this grief was caused by his great love for the President and his sympathy for the Kennedy family. The anguish over the assassination, Ruby stated, finally "reached the point of insanity", suddenly compelling him to shoot when Oswald walked to the police ramp that Sunday morning. At the time of the shooting, Ruby said he was taking phenmetrazine, a central nervous system stimulant. Ruby broke into tears at his bond hearing in January 1964, as he talked to reporters regarding the assassination of President Kennedy. His voice breaking, Ruby said that he could not understand "how a great man like that could be lost". According to an unnamed Associated Press source, Ruby made a final statement from his hospital bed on December 19, 1966, that he alone had been responsible for the murder of Lee Harvey Oswald. "There is nothing to hide ... There was no one else," Ruby said.
