Judge Sherry Stephens did not say what the reason for the questioning was, but the fact she is calling each juror in individually means it is possible she is looking into some kind of misconduct.
The announcement came after a day of questions for a key prosecution witness, Psychologist Janeen Demarte.
Dr. Janeen Demarte testified that Arias had a mental disorder, borderline personality disorder, but not a mental illness, and she knows the difference between right and wrong.
She described Arias as a stalker who could not let go of Travis Alexander, killing him, and then like any other con, tried to get away with the crime.
Dr. Demarte read e-mails Arias sent to Alexander after she'd murdered him to make it look like she hadn't been in Arizona when he was murdered, and musing in her journal about how people suspected she was the killer, but she would never do such a thing.
In a bruising cross-examination, Arias defense attorney Kirk Nurmi ridiculed Dr. Demarte, suggesting she is an inexperienced hired gun. At one point even asking "When did you become this guru of psychological certitude."
The judge read questions from the jurors. They asked how much she knew about treating domestic violence and sexual abuse, and why her tests of Arias are more accurate than the tests done by psychologists hired by the Arias defense team.
There is no trial on Tuesday, the sentencing retrial resumes Wednesday.
