The jury in the Jodi Arias death penalty sentencing retrial was exposed to the creepy messages that Arias sent Travis Alexander after she killed him in effort to cover up the murder.

The prosecution's key witness, psychologist Janeen DeMarte, returned to the witness stand on Monday and read through the e-mails and texts that Arias sent her former boyfriend after she stabbed him 27 times and shot him in the head.

"I haven't heard back from you," read one email, reports AZ Family.

Dr. Demarte also read one of Arias' journal entries that was written after she killed Alexander.

"People are dropping my name about possibly having something to do with Travis' death ... I don't understand it ...I have been praying for his family and the detectives...This is difficult to write about ....I take comfort in knowing the truth will come out soon," it reads.

"It's extremely creepy," said court watcher Jen Wood. "It shows that Jodi Arias was having these conversations with Travis Alexander after she had murdered him, even going so far as saying, "it's too bad the person that did it, hasn't been found yet."

During her testimony, Dr. Demarte noted that Arias had a mental disorder and a borderline personality disorder, rather than a mental illness. She added that the convicted killer knows the difference between right and wrong.

However, the psychologist was subjected to a brutal cross-examination as defense attorney Kirk Nurmi suggested that she is an inexperienced hired pawn. At one point, he asked her, "When did you become this guru of psychological certitude?" reports Fox 10 Phoenix. He even yelled at her.

"It can be dangerous to attack too much," said legal expert Beth Karas. "Especially if the jurors think -- why are you being so hard on her? She's not being evasive."

Testimony in the high profile trial came to an abrupt stop Monday afternoon when Judge Sherry Stephens announced that she wanted to question each member of the jury privately, without giving a reason.

The sentencing retrial will resume Wednesday morning.

Although Arias was found guilty of first-degree murder last May in the death of her ex-boyfriend, in her first trial, jurors failed to reach a unanimous decision on her sentencing. As a result, the retrial will determine whether she should be sentenced to death, life in prison or life with a chance of release after serving 25 years.
