The bitter courtroom war of words between prosecutor Juan Martinez and expert defense witness Alyce LaViolette got even more nasty on Tuesday as the sharp-tongued attorney sarcastically called her "a human lie detector."

The scathing comment was a direct response to his opinion that Jodi Arias blatantly lied to LaViolette from the onset of their interviews about the violent death of Travis Alexander in June 2008.

It set the theme for the day's testimony of "truthfulness."

To prove his point, Martinez played a clip in the Maricopa County Courtroom of the police interrogation interview of Jodi's father, William Arias, where he revealed his daughter hadn't been honest with him since age 14, according to the Arizona Republic.

To which LaViolette, a domestic violence counselor, replied she wouldn't make a decision based on a soundbite. Instead, LaViolette insisted she would evaluate.
