CORRECTS TO A 1997 FILE PHOTO FROM 1987 - FILE - In this 1997 file photo, Kenneth Trentadue, shown in the poster hanging in the office of Oklahoma City lawyer Scott Adams, is pictured in Oklahoma City. Prison officials maintain that Trentadue committed suicide by hanging himself. Trentadue's family and Adams claim that the bruises covering his body are inconsistent with that type of death. Starting Monday, July 28, 2014, in a federal court trial in Salt Lake City, the FBI will have to persuade a judge they’ve really done everything possible to find video tapes of Timothy McVeigh minutes before he parked a truck outside the Oklahoma City federal building in 1995 and detonated a bomb that killed 168 people. The trial is the culmination of a nearly two-decade long quest by Salt Lake City attorney Jesse Trentadue to explain his brother’s mysterious jail cell death 19 years ago in Oklahoma. (AP Photo/J.
