WASHINGTON – For hours after allegedly trying to use a bomb hidden in his underwear to blow up a Christmas Day flight to Detroit, Umar Farouk Abdulmutallab talked and talked — to Customs officers, medical personnel, and FBI agents.
He spoke openly about what he'd done and why, and provided valuable intelligence, U.S. officials told The Associated Press in a series of interviews that spell out for the first time the details of Abdulmutallab's arrest and questioning on Dec. 25.
Badly burned and bleeding, the suspect tried one last gambit as he was taken from the plane: He claimed there was another bomb hidden on board, officials said.
There was no second bomb, federal agents learned after a tense search. But the Nigerian suspect's threat set off a series of conversations that are now the subject of a fierce political debate over the right way to handle terrorism suspects.
The bomb had severely burned Abdulmutallab, but he was still conscious. As he was taken from the scene, federal agents repeatedly interviewed him or heard him speak to others. But when they read him his legal rights nearly 10 hours after the incident, he went silent.
Since the attempted bombing, several prominent lawmakers have argued he should have been placed immediately in military custody, and the nation's top intelligence official said he should have been questioned by a special group of terror investigators, rather than the FBI agents who responded to the scene.
The officials who spoke to The AP said on-scene investigators never discussed turning the suspect over to military authorities. And their accounts show that as the hours passed, the FBI turned to its own local expert counterterror interrogators, rather than seek bureau personnel to fly in from Washington or elsewhere.
The officials provided an account of the law enforcement response to the holiday bombing on condition of anonymity because they were not authorized to disclose details of the investigation.
Abdulmutallab's attorney, Miriam Siefer, did not immediately return a message left Sunday for comment.
Here is what officials say happened:
Shortly after noon on Christmas, federal agents were notified that Northwest Airlines flight 253 had arrived at the Detroit airport from Amsterdam, with a passenger who had lit an explosive device on the aircraft.
After being restrained and stripped bare by fellow passengers and crew, Abdulmutallab was handed over to Customs and Border Protection officers and local police.
The officers and an ambulance crew took him to the burn unit at the University of Michigan Medical Center.
Along the way, Abdulmutallab repeatedly made incriminating statements to the CBP officers guarding him. He told them he had acted alone on the plane and had been trying to take down the aircraft.
Abdulmutallab arrived at the hospital just before 2 p.m. Still under guard, Abdulmutallab told a doctor treating him that he had tried to trigger the explosive. The Nigerian said it didn't cause a blast, but instead began popping and ignited a fire on his groin and legs.
FBI agents from the Detroit bureau arrived at the hospital around 2:15 p.m., and were briefed by the Customs agents and officers as Abdulmutallab received medical treatment.
Shortly after 3:30 p.m., FBI agents began interviewing the suspect in his hospital room, joined by a CBP officer and an Immigration and Customs Enforcement agent.
The suspect spoke openly, said one official, talking in detail about what he'd done and the planning that went into the attack. Other counterterrorism officials speaking on condition of anonymity said it was during this questioning that he admitted he had been trained and instructed in the plot by al-Qaida operatives in Yemen.
Al-Qaida leader Osama bin Laden, in a brief recording carried Sunday by the Al-Jazeera Arabic news channel, claimed responsibility and promised there would be more attacks on the U.S.
The FBI interview with the suspected bomber lasted about 50 minutes. Before they began questioning Abdulmutallab, the FBI agents decided not to give him his Miranda warnings informing him of his right to remain silent.
While the Miranda warning — based on a 1966 Supreme Court ruling — is a bedrock principle of the U.S. justice system and a staple of television cop shows, there is a major exception which could apply in Abdulmutallab's case.
Investigators are allowed to question a suspect without providing a Miranda warning if they are trying to end a threat to public safety.
In a future trial in a federal court, prosecutors would likely justify Abdulmutallab's questioning without a Miranda warning by arguing that the FBI agents needed to know quickly if there were other planes with other bombs headed for the United States. The 9/11 attacks and other past plots have shown al-Qaida's penchant for synchronized attacks in multiple locations.
Since the incident, Republican lawmakers have argued that the Obama administration mishandled the case by not considering putting Abdulmutallab in military custody — part of a larger political argument about whether terror suspects should face military or civilian justice.
"Those who now argue that a different action should have been taken in this case were notably silent when dozens of terrorists were successfully prosecuted in federal court by the previous administration," Justice Department spokesman Matthew Miller said earlier this week.
Abdulmutallab's interview ended when the suspect was given medication and the investigators decided it would be better to let the effects of the drugs wear off before pressing him further.
The suspect went into surgery, and would not be questioned again for more than five hours.
By that time, FBI bosses in Washington had decided a new interrogation team was needed. They made that move in case the lack of a Miranda warning or the suspect's medical condition at the time of the earlier conversations posed legal problems later on for prosecutors.
There was no effort to call in the elite federal High-Value Interrogation Group, a special unit of terror specialists that the Obama administration said early last year it would create to deal with terror suspects captured abroad.
Last week, Director of National Intelligence Dennis Blair said the unit should have been called in after Abdulmutallab's arrest. But even if federal officials wanted to expand its use to domestic cases, the special team was not ready for action, FBI Director Robert Mueller told Congress last week.
Based on the instructions from Washington, the second interview was conducted by different FBI agents and others with the local joint terrorism task force.
Such a move is not unusual in cases where investigators or prosecutors want to protect themselves from challenges to evidence or statements.
By bringing in a so-called "clean team" of investigators to talk to the suspect, federal officials aimed to ensure that Abdulmutallab's statements would still be admissible if the failure to give him his Miranda warning led a judge to rule out the use of his first admissions.
Even if Abdulmutallab's statements are ruled out as evidence, they still provided valuable intelligence for U.S. counterterrorism agents to pursue, officials said.
In the end, though, the "clean team" of interrogators did not pry more revelations from the suspect.
Having rested and received more extensive medical treatment, Abdulmutallab was told of his right to remain silent and right to have an attorney.
He remained silent.
