PHOENIX (AP) - The prosecutor pounded his hand on the table to make his point and alternated between a loud demeanor and a soft-spoken, cordial tone as he told the jury time and time again: Jodi Arias is a manipulative liar and a killer.
    
The dramatic closing argument by prosecutor Juan Martinez came as family members of the victim sobbed in the front row and an unemotional Arias meticulously scribbled notes with a pencil. People lined up at 2 a.m. to get a seat in the courtroom for the spectacle with only two rows in the gallery available for the public.
    
"It's like a field of lies that has sprouted up around her as she sat on the witness stand," Martinez said of Arias, who previously spent 18 days testifying. "Every time she spat something out, another lie."
    
Arias, 32, is charged with first-degree murder in the 2008 stabbing and shooting death of her on-and-off-again boyfriend Travis Alexander in a case that has become a tabloid and cable TV sensation.
    
Authorities say Arias planned the attack on Alexander in a jealous rage after he wanted to end their relationship and prepared for a trip to Mexico with another woman. Arias initially denied any involvement in the killing then later blamed it on masked intruders. Two years after her arrest, she said she killed him in self-defense. Her lawyers will present their closing arguments Friday.
