Was Jodi Arias an obsessive stalker who struck fear into the heart of the victim long before she stuck a blade into it?

That is the portrait that was painted by prosecutor Juan Martinez on day 44 of her death row murder trial.

Once again, defense witness Alyce LaViolette, a domestic violence expert, faced a brutal cross examination from Martinez, who presented  an email saying that victim Travis Alexander was "extremely fearful" of his Arias, 32, who he described as a stalker.

The defense expert witness disagreed and at one point, even told Martinez he was "asking me very incomplete questions."

"You see the world as good or bad, Mr. Martinez... I see lots of shades of gray," she told him.

Following a number of antagonistic sidebars , Martinez asked again: "Isn't it true Mr. Alexander was extremely afraid of the defendant... because of her stalking behavior?"
