In a setback for Joran Van der Sloot, Luz Marina Romero Chinchay, the mysterious attorney who appeared with him when he gave his confession, has surfaced after being sued by his current attorney (background on lawsuit here.)

In an interview to CNN's "In Session," she insists Joran retained her, promising payment from his mother, and that his confession was voluntary.

She also maintains Joran and she conversed in "perfect Spanish," and questions his truthfulness:

She also questioned the truthfulness of van der Sloot. For instance, when he signed some documents after talking to his mother, Romero noticed that he signed very differently than what he signed on the police statement, she said.

"I told him, 'you signed differently' and he winked his eye and made a silence signal with his hands," Romero said.

She denies she was working with the authorities, but doesn't say who arranged for her to meet Joran in the first place.
