U.S. Said to Have Tapes of Alleged 9/11 Mastermind Plotting With Co-Conspirators

The tapes featuring Khalid Shaikh Mohammed and 3 of his accused co-conspirators were made between April and October 2001, prosecutors say.

Military prosecutors say they have tapes of telephone calls between the alleged mastermind of the Sept. 11 attacks, Khalid Shaikh Mohammed, and 3 of his accused co-conspirators talking in code about the plot months before it took place, a defense lawyer disclosed on Monday.

The lawyer, Jay Connell, revealed the existence of the tapes as part of a protest over plans to use them as evidence at the death penalty trial of the alleged conspirators. More than 17 1/2 years after the attacks — in which 19 hijackers commandeered 4 commercial airplanes and crashed them into the World Trade Center, the Pentagon and a Pennsylvania field, killing nearly 3,000 people — there is still no date set for the trial in the proceedings at Guantánamo Bay.

Prosecutors gave defense lawyers the original audio and transcripts of their translation on Sept. 30, 2016, Mr. Connell said, and made clear they planned to use them at trial. Defense lawyers sought to investigate their origins and later discovered that the original trial judge, Army Col. James L. Pohl, had issued a secret order preventing them from knowing about the phone call collection system or asking questions about it.

Mr. Connell, who is representing Mr. Mohammed’s nephew, Ammar al-Baluchi, said that prosecutors secretly obtained a ruling in August 2018 from Colonel Pohl forbidding defense lawyers from learning how the phone calls were collected or investigating that question. The phone calls in at least two languages were made between April and October 2001.

Mr. Connell said the restriction on investigating the origins of the tapes violated a defendant’s basic right to challenge the evidence being used against him. He argued in court on Monday that the evidence should be suppressed or that the case should be dismissed. He said the constraints the defense faces regarding the tapes violate the Sixth Amendment, which sets out the rights of defendants in a trial.

The military trial judges have yet to decide, however, which aspects of the Constitution apply at the military commissions, the war court established by President George W. Bush after the terrorist attacks.

A prosecutor, Clayton Trivett, responded that defense lawyers would be allowed to question an F.B.I. linguist who compared samples of the voices of the defendants to the voices on the tapes to confirm they were Mr. Mohammed, Mr. al-Baluchi and 2 other alleged plotters.

Mr. Trivett said defense lawyers would be allowed to question an F.B.I. analyst who decoded the conversation. The only restriction, he said, is on defense lawyers trying to investigate “how the United States government got those calls,” something prosecutors persuaded the judge would endanger national security.

Colonel Pohl had said prosecutors could describe the evidence as having been acquired from “telephone calls from between April and October 2001 that were later determined to pertain to the planned attacks on Sept. 11, 2001.”

Terry McDermott, co-author of “The Hunt for KSM,” said his research found that United States satellites “randomly scooped up” calls between Mr. Mohammed and an alleged deputy, Ramzi bin al-Shibh. “The N.S.A. intercepted calls but didn’t listen to them or translate them until after 9/11,” he said. “Afterward, they went through this stuff and found out what it was.”

Mr. Trivett did not disclose how or when the F.B.I. got voice samples of the accused plotters. Mr. Connell questioned in court whether they were recorded during the years that Mr. Mohammed and the other the defendants were held in the C.I.A.’s secret prison system.

Mr. Trivett announced that the samples were not from the C.I.A. black sites where the five alleged plotters were held before they were brought to Guantánamo for trial in 2006.

This week a new military judge, Col. Keith Parrella of the Marines, is hearing lawyers and prosecutors argue in the 34th round of pretrial hearings since the 5 men were arraigned in 2012.

Georgia parole board suspends scheduled execution of Cobb County death row prisoner

The execution of a Georgia man scheduled for Wednesday has been suspended as the State Board of Pardons and Paroles considers a clemency application.  Stacey Humphreys, 52, would have been the state's first execution in 2025. As of December 16, 2025, Georgia has carried out zero executions in 2025. The state last executed an inmate in January 2020, followed by a pause due to COVID-19. Executions resumed in 2024, but none have occurred this year until now. Humphreys had been sentenced to death for the 2003 killings of 33-year-old Cyndi Williams and 21-year-old Lori Brown, who were fatally shot at the real estate office where they worked.

Oklahoma board recommends clemency for inmate set to be executed next week

A voting board in Oklahoma decided Wednesday to recommend clemency for Tremane Wood, a death row inmate who is scheduled to receive a lethal injection next week at the state penitentiary in McAlester.  Wood, 46, faces execution for his conviction in the 2001 murder of Ronnie Wipf, a migrant farmworker, at an Oklahoma City hotel on New Year's Eve, court records show. The recommendation was decided in a 3-2 vote by the Oklahoma Pardon and Parole Board, consisting of five members appointed by either the governor or the state's top judicial official, according to CBS News affiliate KWTV. Oklahoma Gov. Kevin Sitt will consider the recommendation as he weighs whether to grant or deny Wood's clemency request, which would mean sparing him from execution and reducing his sentence to life in prison without the possibility of parole.
