<P> As the rescue effort wound down, the media interest shifted to the investigation, arrests, and trials of Timothy McVeigh and Terry Nichols, and on the search for an additional suspect named "John Doe Number Two ." Several witnesses claimed to have seen a second suspect, who did not resemble Nichols, with McVeigh . </P> <P> Those who expressed sympathy for McVeigh typically described his deed as an act of war, as in the case of Gore Vidal's essay The Meaning of Timothy McVeigh . </P> <P> The Federal Bureau of Investigation (FBI) led the official investigation, known as OKBOMB, with Weldon L. Kennedy acting as Special Agent in charge . Kennedy oversaw 900 federal, state, and local law enforcement personnel including 300 FBI agents, 200 officers from the Oklahoma City Police Department, 125 members of the Oklahoma National Guard, and 55 officers from the Oklahoma Department of Public Safety . The crime task force was deemed the largest since the investigation into the assassination of John F. Kennedy . OKBOMB was the largest criminal case in America's history, with FBI agents conducting 28,000 interviews, amassing 3.5 short tons (3.2 t) of evidence, and collecting nearly one billion pieces of information . Federal judge Richard Paul Matsch ordered that the venue for the trial be moved from Oklahoma City to Denver, Colorado, citing that the defendants would be unable to receive a fair trial in Oklahoma . The investigation led to the separate trials and convictions of McVeigh, Nichols, and Fortier . </P> <P> Opening statements in McVeigh's trial began on April 24, 1997 . The United States was represented by a team of prosecutors led by Joseph Hartzler . In his opening statement Hartzler outlined McVeigh's motivations, and the evidence against him . McVeigh, he said, had developed a hatred of the government during his time in the army, after reading The Turner Diaries . His beliefs were supported by what he saw as the militia's ideological opposition to increases in taxes and the passage of the Brady Bill, and were further reinforced by the Waco and Ruby Ridge incidents . The prosecution called 137 witnesses, including Michael Fortier and his wife Lori, and McVeigh's sister, Jennifer McVeigh, all of whom testified to confirm McVeigh's hatred of the government and his desire to take militant action against it . Both Fortiers testified that McVeigh had told them of his plans to bomb the Alfred P. Murrah Federal Building . Michael revealed that McVeigh had chosen the date, and Lori testified that she created the false identification card McVeigh used to rent the Ryder truck . </P>
