Ghislaine Maxwell, the late Jeffrey Epstein’s girlfriend who was convicted of securing underage girls for him and others, returned to the Florida prison where she’s serving her sentence carrying a “mystery box.”

CNN’s Erin Burnett noted the strange occurrence during a show segment on Thursday, showing a clip of Maxwell holding the box and entering the prison following what was reportedly a meeting with Deputy Attorney General Todd Blanche.

Another user posted a clearer photo of a figure purported to be Maxwell holding a box as a guard opens a door for her.

“Today, I met with Ghislaine Maxwell, and I will continue my interview of her tomorrow,” Blanche said in a social media post. “The Department of Justice will share additional information about what we learned at the appropriate time.”

Blanche said he would be meeting with Maxwell again on Friday, according to CNN. Blanche and Maxwell met at the US attorney’s office in Tallahassee, Fla., the outlet added.

Maxwell’s attorney David Oscar Markus called her meeting with Blanche “productive,” adding that she answered all of his questions “honestly.”

“Looking forward to another productive day,” Markus told CNN Thursday night. “Ghislaine honestly answered every question that Mr. Blanche asked. And she will continue to do so.”

The meetings follow the Department of Justice’s recent outreach to Epstein’s former associate. Blanche said in a statement on Tuesday that if “Ghislane Maxwell has information about anyone who has committed crimes against victims, the FBI and the DOJ will hear what she has to say.”
