Oklahoma City bomber Timothy McVeigh, 33, was executed on Monday morning in the death chamber at the federal penitentiary in Terre Haute, Ind. The man responsible for killing 168 people in the single worst act of terrorism on American soil was pronounced dead at 7:14 a.m. CDT, according to warden Harley Lappin. McVeigh made no final statement, said Lappin, who described McVeigh as "calm" and "cooperative" throughout the procedure. Some 250 witnesses, including survivors and family members of victims, watched the execution over live closed-circuit TV. McVeigh reportedly had spent a calm final night in a small, windowless cell not far from the execution room and had ordered two pints of mint-chocolate-chip ice-cream as his final meal. Post-execution plans called for his body to be cremated and the ashes turned over to his lawyers, who apparently will scatter them in a secret location. In a letter published Sunday in the Buffalo Evening News, McVeigh professed that he had once considered having his ashes scattered near the memorial in Oklahoma City, where he blew up the Alfred P. Murrah Federal Building on April 19, 1995. But, he said, such a decision would be too vengeful, raw and cold. "He doesn't want to do anything to cause any further pain," one of his attorneys, Nathan D. Chambers, told The New York Times.
