Long-secret security tapes showing the chaos immediately after the 1995 bombing of the Oklahoma City federal building are blank in the minutes before the blast and appear to have been edited, an attorney who obtained the recordings said Sunday. The real story is what's missing," said Jesse Trentadue, a Salt Lake City attorney who obtained the recordings through the federal Freedom of Information Act as part of an unofficial inquiry he is conducting into the April 19, 1995, bombing that killed 168 people and injured hundreds more. The tapes turned over by the FBI came from security cameras various companies had mounted outside office buildings near the Alfred P. Murrah Federal Building. They are blank at points before 9:02 a.m., when a truck bomb carrying a 4,000-pound fertilizer-and-fuel-oil bomb detonated in front of the building, Trentadue said. "Four cameras in four different locations going blank at basically the same time on the morning of April 19, 1995. There ain't no such thing as a coincidence," Trentadue said. He said government officials claim the security cameras did not record the minutes before the bombing because "they had run out of tape" or "the tape was being replaced." "The absence of footage from these crucial time intervals is evidence that there is something there that the FBI doesn't want anybody to see." Trentadue said he is seeking more tapes along with a variety of bombing-related documents from the FBI and the CIA. An FOIA request by Trentadue for 26 CIA documents was rejected in June. A letter from the National Geospatial-Intelligence Agency, which reviewed the documents, said their release "could cause grave damage to our national security."
