A New York woman was recently arrested with her husband on charges of trying to laundered $4.5 billion worth of stolen digital currency.
The talks were cited in a request by prosecutors asking a judge to delay the status hearing for the woman.
Prosecutors said in a court filing that the postponement would facilitate plea discussions between the parties, as well as give them time to assemble and share evidence that could be used against Morgan with her attorneys.
Morgan and her husband were arrested in their Manhattan apartment. On the same day that the arrests were made, the Justice Department said it had seized more than $3.6 billion worth of the virtual currency.
The couple is accused of trying to hide the source of almost $120,000 worth of bitcoin that was stolen during the Bitfinex hack. The defendants are not charged with the hack itself.
At the time of the hack, it was worth $70 million. Since then, the value of the virtual currency has gone up.
According to Monday's filing by the U.S. Attorney's Office for the District of Columbia, Morgan's lawyers do not oppose the postponement of her hearing.
The prosecutors said in court that they were discussing a possible resolution of the case to avoid a trial.
They did not use the words "plea discussions" to describe them.
Morgan's lead attorney did not respond to the request for comment.
It is common for prosecutors and defense attorneys to discuss possible plea deals in criminal cases, and for those discussions to lead to postponements of court hearings.
Morgan's case is unusual for the short time between her arrest and the disclosure of plea talks.
Morgan is free on a $3 million bond.
Lichtenstein has been in jail since his arrest.
Chris Smith, who was executive producer of the company's Covid smash hit Tiger King, will be directing a series on the couple.
