Two week after his arrest Adis Medunjanin, the Queens College grad and friend of alleged subway bomber Najibullah Zazi, has told Feds all about his own terrorist actions and those of his co-conspirators. A letter filed by prosecutors says the loose-lipped suspect—who is himself charged with getting Qaeda training and conspiring to murder American soldiers—provided investigators with “very detailed information” about “terrorist-related activities.” Meanwhile, Medunjanin’s lawyer Robert Gottlieb continues to argue that the FBI held and questioned his client illegally.

According to the court letter from Assistant Brooklyn US Attorney James Loonam, Medunjanin spoke freely to investigators, waiving his right to a lawyer and telling them he no longer wished to be represented by Gottlieb. It wasn’t the first time he’d given up his rights: on January 7 and 8 he waived his Miranda rights and signed a waiver that said he was being charged with receiving Qaeda training, the NY Times reported. “The defendant made clear to the agents that he desired to cooperate with the government, and provided very detailed information about terrorist-related activities of himself and others in the United States and Pakistan,” Loonam wrote.

But after Medunjanin was indicted by a grand jury he was asked to sign another waiver—this time it added a charge of plotting murder to the training allegation. The letter says Medunjanin “expressed concern” about the murder charge and “stated, in sum and substance, ‘Maybe I should talk to Mr. Gottlieb.’” Gottlieb, who wants his client’s statement to be suppressed, says the letter supports his argument. “Finally, the government has conceded that my client wanted to speak to his lawyer,” he said.
