After a hearing, Judge Matsch independently ruled the evidence concerning a larger conspiracy to be too insubstantial to be admissible. In addition to arguing that the bombing could not have been carried out by two men alone, Jones also attempted to create reasonable doubt by arguing that no one had seen McVeigh near the scene of the crime, and that the investigation into the bombing had lasted only two weeks. Jones presented 25 witnesses over a one-week period, including Frederic Whitehurst. Although Whitehurst described the FBI's sloppy investigation of the bombing site and its handling of other key evidence, he was unable to point to any direct evidence that he knew to be contaminated. A key point of contention in the case was the unmatched left leg found after the bombing. Although it was initially believed to be from a male, it was later determined to be that of Lakesha Levy, a female member of the Air Force who was killed in the bombing. Levy's coffin had to be re-opened so that her leg could replace another unmatched leg that had previously been buried with her remains. The unmatched leg had been embalmed, which prevented authorities from being able to extract DNA to determine the leg's owner. Jones argued that the leg could have belonged to another bomber, possibly John Doe No. 2. The prosecution disputed the claim, saying that the leg could have belonged to any one of eight victims who had been buried without a left leg. Numerous damaging leaks, which appeared to originate from conversations between McVeigh and his defense attorneys, emerged. They included a confession said to have been inadvertently included on a computer disk that was given to the press, which McVeigh believed seriously compromised his chances of getting a fair trial. A gag order was imposed during the trial, prohibiting attorneys on either side from commenting to the press on the evidence, proceedings, or opinions regarding the trial proceedings. The defense was allowed to enter into evidence six pages of a 517-page Justice Department report criticizing the FBI crime laboratory and David Williams, one of the agency's explosives experts, for reaching unscientific and biased conclusions. The report claimed that Williams had worked backward in the investigation rather than basing his determinations on forensic evidence. The jury deliberated for 23 hours. On June 2, 1997, McVeigh was found guilty on 11 counts of murder and conspiracy. Although the defense argued for a reduced sentence of life imprisonment, McVeigh was sentenced to death. In May 2001, the Justice Department announced that the FBI had mistakenly failed to provide over 3,000 documents to McVeigh's defense counsel.
