The massive nationwide investigation aimed at establishing the guilt of those responsible for the Oklahoma City Bombing is continuing at this time. While the investigation has been intense and vigorous, much remains to be done. The vast amount of evidence to be gathered and analyzed makes this investigation one of extraordinary complexity. Thousands of investigative leads have been followed to their conclusion, but many remain to be pursued. As of the date of this Motion, records of more than 100,000 phone calls have been analyzed, but tens of thousands more await analysis.
Agents are in the process of analyzing thousands of business records.
Moreover, forensic analyses of hundreds of pieces of evidence obtained over the life of the investigation is underway but not complete. From the bomb scene alone, approximately 7,720 pounds of evidence have been collected, which are presently being subjected to myriad chemical and physical tests designed to detect the presence of explosive residue. Frequently, six or more hours must be devoted to the testing of a single piece of bomb scene evidence. Such evidence is being subjected to gas chromatography and liquid chromatography tests, X-ray tests, and microscopic analyses, among others. In addition, fingerprinting and handwriting analyses are presently being performed on a considerable number of items.
