Jodi Arias' history of lying was a well-known to the prosecutor who put her behind bars for life without the possibility of parole.
Juan Martinez, author of Conviction: The Untold Story of Putting Jodi Arias Behind Bars, told acid-tongue HLN host Nancy Grace that Arias' attempt to spin the meaning of the vulgar slur she used against a guard was typical of the convicted criminal.
Radar exclusively revealed that Arias was found guilty of calling a Perryville Prison guard a "c**k blocker," and lost her contact visitation privileges. But the woman who spent hours having X-rated phone sex with Travis Alexander claimed that she didn't know the phrase had a sexual connotation.
"That's what she says," Martinez told Grace. "She said a lot of things during the trial."
A jury did not buy Arias' version of events that led to the brutal slaughter of Alexander, and Martinez said her penchant for lying was evident during her trial.
"That's the problem with dealing with her. Whatever she says always has to meet her criteria. What she says doesn't really mean much."
Martinez sparred with Arias when she took the stand in her own defense, and told Grace he knew she was being dishonest.
"Most of the time she has a problem with the truth."
He also revealed why Arias was so vindictive toward him.
"I was the person that actually was holding her accountable," he explained. "It didn't seem in her past that many people had held her accountable for what she had done. It appeared that I was probably the first person who had brought her deeds out to light so we could discuss them."
