Alexandria , Virginia -- Two suspects charged with having served as deep-cover Russian agents living in the United States have told investigators they are Russian citizens and have been living under false identities , according to a court document released Friday . A letter from prosecutors opposing bail for the suspects said that the man known as Michael Zottoli is really a Russian named Mikhail Kutzik . The government also said the woman known as Patricia Mills is a Russian citizen named Natalia Pereverzeva . Prosecutors said that the couple waived their rights to remain silent and made the admissions soon after being arrested at their Arlington , Virginia residence over the weekend . The two were living as a married couple and have two small children . The government document also said searches of the couple 's home and two safe-deposit boxes they rented revealed that they contained cash , passports and other identity documents bearing their false identities . Investigators said they found $ 80,000 in one of the safe-deposit boxes . It was divided into eight unmarked envelopes , each of which contained $ 10,000 in what appeared to be new $ 100 bills , they said . The document said another safe-deposit box rented by the two held $ 20,000 along with passports and other documents bearing their fake identities . Prosecutors said a laptop found in the couple 's home had been brought from Russia to the United States by a co-conspirator and given to Zottoli , as court papers referred to him , in March . The revelations are contained in a letter from federal prosecutors opposing bail for the couple and for another suspect named Mikhail Semenko . The pair and Semenko remain in custody in Northern Virginia . They waived their rights to ask for bail in hearings at U.S. District Court in Alexandria , Virginia on Friday afternoon . Zottoli and Mills , as court papers called her , appeared in court wearing dark-green jail jumpsuits emblazoned with `` prisoner '' on the back of each . They did not speak to each other in court . They spoke only to give their assent when the judge asked if they realized they were waiving their rights to ask for bail . Prosecutors had hoped to get the suspects moved quickly to New York to stand trial with seven others arrested in the case . But attorneys for the three requested a preliminary hearing a judge scheduled for July 7 . Semenko appeared at a separate hearing afterward . He too was dressed in a green jail jumpsuit . He spoke quietly with a slight Russian accent when asked if he understood he was relinquishing his right to ask for bail . Magistrate Judge Theresa Buchanan ordered that the three continue to be held in jail and cited the government 's contention they are dangers to the community and a flight risk . Following the court proceedings , CNN asked Semenko 's attorney Daniel Lopez why he wanted a preliminary hearing for his client . `` He 's entitled to a preliminary hearing , '' replied Lopez . The defense attorney indicated the government would be expected to reveal more of its case against his client at the preliminary hearing on Wednesday .
