Accused murderer Jodi Arias has a Twitter account and has been using someone outside of jail to write tweets slamming Arizona prosecutor Juan Martinez and HLNTV's Nancy Grace.

Fox 10 News learned that Arias - who is on a high-profile trial for the murder of her ex-lover Travis Alexander - speaks to her friend Donovan Bering every night on the phone and tells her what to tweet to Arias' 18,000-plus followers. Bering has been sitting in the gallery during the three-month trial beside Arias' mother, Sandra Arias, and confirmed that she handles Jodi's Twitter account.

"She'll call and say 'I have a quote,'" Bering said, according to the news report. "We'll talk about it. Sometimes she says 'let's tweet.' And then she'll say 'no let's not do it. "I think it's a way of her getting out her frustration, because she doesn't have a chance to say much."

Bering has tweeted, at Jodi's suggestion, several comments slamming Martinez.

"Hmm... Anger Management problems anyone?" reads Jodi's Twitter feed. "He who tries to establish his point by much yelling shows that his reasoning is weak," and, "Those afflicted with Little Man's Syndrome taint society's perception of genuinely good men who happen to be vertically challenged."

Jodi's friend also helped the alleged murder clear up rumors that she has been in a relationship while behind bars. In one tweet Bering wrote: "No, I do not have a girlfriend. After everything I've been through it's amazing I'm not gay." In another she tweeted, "No boyfriend. Enough of that rumor."

Bering also helped Jodi respond to a tweet posted about her by HLNTV's Nancy Grace. After Grace tweeted a picture of Jodi making an obscene gesture with her hand in court, Jodi arranged for Beringer to write: "Actually Nancy, that finger was for you. Have a nice day," and, "HLN is an acronym for Haters Love Negativity."

The Maricopa County Sheriff's Office admitted that they are aware of Jodi's Twitter account and cannot do anything to stop it because she has not been convicted.

"We do talk about the fact that Jodi seems to be able to reach out into the community in various ways and profit from her notoriety. We don't like it... but there is nothing we can do about it," Lisa Allen, a Maricopa County Sheriff's Office spokesman, told the news station..

Jodi's attorneys are also aware that she has a Twitter account and are not happy about it, according to the report.

Jodi has been on trial since Jan. 4 because autopsy records showed that she stabbed Alexander over 27 times, slit his throat from ear to ear and shot him in the head. According to police, she lied twice at first about how Alexander was killed and later admitted that she killed him in an act of self-defense. If she is convicted of the murder and the lies that she confessed to, she will likely face the death penalty and become the fourth woman in Arizona's history to die by lethal injection.

The live court session for Jodi' first-degree murder trial will resume on Monday, April 15, for the 2008 Arizona killing of Alexander.
