The time has come for the public to learn who at least some of the alleged customers of the Greater Boston brothels when the first of three sets of hearings take place today at Cambridge District Court.

The court clerk’s office released a notice in late January that show-cause will take place on three consecutive Fridays in March, with the first being today. No information was provided in the notice so the courtroom will be the first place the public learns of their identities.

“No continuances will be granted, absent extraordinary circumstances,” the hearing order stated.

On Nov. 8, 2023, the U.S. Attorney for the District of Massachusetts announced the arrest of three people accused of running a high-end brothel out of the suburbs around Boston and Washington D.C.

The leader, or madame, of the operation, Han “Hanna” Lee, of Cambridge, pleaded guilty last September and her errand boy and “booker” Junmyung Lee, of Dedham, followed suit the next month. The third operator, James Lee, of Torrance, California, pleaded guilty late last month to his role in the operation. Prosecutors say he secured a number of false identities to rent the apartments where the sex took place.

The trio, who are not related according to prosecutors, were arrested in November 2023 and indicted by a federal grand jury the following February.

But the clients of the illicit trade have never been identified.

Prosecutors said clients included “elected officials, high tech and pharmaceutical executives, doctors, military officers, government contractors that possess security clearances, professors, attorneys” and others, and a Homeland Security investigator filed applications for criminal charges against 28 alleged johns in December.

“Pick a profession, they’re probably represented in this case,” then-U.S. Attorney Joshua Levy said in November 2023 while announcing the case. “They are the men who fueled this commercial sex ring.”

The alleged customers fought hard to keep their charges private, but ultimately the Massachusetts Supreme Judicial Court ruled in November that the show-cause hearings would be public.

The court found that the “the clerk-magistrate acted reasonably and within the proper scope of her discretion” when she decided to grant public access to the hearings. That the U.S. Attorney’s office provided public notice that the defendants were powerful “raised legitimate public concerns about potential favoritism and bias if such hearings were held behind closed doors, and that these concerns outweighed the interests in continued anonymity for the Does.”

This is a developing story.
