Oklahoma City bombing: 28 years later, key questions remain unanswered Timothy McVeigh and Terry Nichols faced three trials and a vast FBI investigation – but many details of their attack remain unexplained Rescue workers stand in front of the Alfred P Murrah Federal Building, following an explosion on 19 April 1995, in downtown Oklahoma City. Photograph: David Longstreath/AP Twenty five years ago, on 19 April 1995, a disaffected veteran namedTimothy McVeigh drove a Ryder truck stuffed with explosives into downtown Oklahoma City and destroyed a federal office building, killing 168 people, including 19 children, and maiming hundreds of others. That much we know. We also know that, within 90 minutes of the bombing, McVeigh was pulled over near the Kansas border and arrested, alone, at the wheel of a glaringly improbable getaway car, an ancient, spluttering rust bucket of a Mercury sedan with no licence plates, which made him a sitting duck for any passing highway patrolman.
