The Simpson prosecution may conclude its rebuttal with FBI agent William Bodziak, who is back on the stand talking about shoes. The defense spent the weekend interviewing FBI agent Frederic Whitehurst. Judge Ito must decide if Whitehurst's allegations -- that another FBI agent who worked on the Simpson investigation gave false testimony to benefit the prosecution -- are relevant enough to be presented to the jury. Defense attorneys also hope to present potentially damaging evidence about Detective Phillip Vannatter. They claim Vannatter told a witness in another case that he believed Simpson to be a suspect even before police entered Simpson's estate the morning after the murders.
