Larry Potts was the FBI supervisor who was responsible for the tragedies at Ruby Ridge in 1992, and Waco in 1993. Potts was then given responsibility for investigating the OKC bombing. Terry Nichols claimed that McVeigh—who allegedly had been recruited as an undercover intelligence asset while in the Army—had been working under the supervision of Potts.
Terry Yeakey, an officer of the OKC Police Department, was among the first to reach the scene and he was heralded as a hero for rescuing many victims. Yeakey was also an eyewitness to conversations and physical evidence that convinced him that there was a cover-up of the bombing by federal agents. Yeakey was committed to getting to the truth about what happened but a year after the bombing he was found dead off the side of a rural road. His death was ruled a suicide despite overwhelming evidence that he was murdered. Authorities reported that Yeakey, “slit his wrists and neck… then miraculously climbed over a barbed wire fence… walked over a mile’s distance, through a nearby field, and eventually shot himself in the side of the head at an unusual angle.” No weapon was found, no investigation was conducted, no fingerprints were taken, and no interviews were conducted. His family continues to fight for the truth about his death.
