Mike Gilbert is a retired sports agent for athletes including former NFL players Marcus Allen and O. J. Simpson. Gilbert is also the author of "How I Helped OJ Get Away with Murder: The Shocking Inside Story of Violence, Loyalty, Regret and Remorse." The book, published by Regnery Publishing in May, 2008, discusses Gilbert's 18-year-long relationship with O. J. Simpson, including the influence of their personal and professional relationship in the lead up to, during, and following the trials surrounding the murders of Nicole Brown Simpson and Ron Goldman. In May 2008, Mike Gilbert, one of O.J.'s former sports agents, released his book How I Helped O.J. Get Away with Murder, in which he revealed that the gloves did not fit because, on his advice, Simpson had stopped taking his arthritis medicine, which made his hands swell. In May 2008, Mike Gilbert, a former agent and friend of Simpson, released his book How I Helped O.J. Get Away with Murder, which details Simpson confessing to the killings to Gilbert. Gilbert describes how Simpson, having smoked marijuana, taken a sleeping pill, and while drinking beer, confided to him at his Brentwood home weeks after his trial what happened the night of the murders. Simpson said, "If she hadn't opened that door with a knife in her hand... she'd still be alive." This, Gilbert said, confirmed his belief that Simpson had confessed.Mike Gilbert was also alleged to be the source of some of the memorabilia items that Simpson tried to recover from two memorabilia dealers at the Palace Station Hotel Casino in Las Vegas, Nevada. O. J. Simpson was later convicted of all charges and sentenced to serve 9 to 33 years in a Nevada State prison.
