Jodi Arias doesn't have access to a computer while behind bars in a Phoenix jail, but that has not stopped the woman at the center of the country's most high-profile murder trial from joining Twitter.
ABC News has confirmed that Arias' friend Donavan Bering has maintained a Twitter account since mid-February bearing Arias' name and photo. Arias dictates her messages to Bering, who distributes her thoughts daily to her nearly 16,000 Twitter followers, a number that has nearly quadrupled since the account was revealed.
Many of the tweets are often attacks on prosecutor Juan Martinez and the media coverage surrounding the trial, which started in January.
Arias, 32, is on trial for allegedly murdering ex-boyfriend Travis Alexander in June 2008. Arias said she killed Alexander, 30, in self-defense after he attacked her, forcing her to fight for her life. Alexander suffered nearly 30 knife wounds, was shot in the head and had his throat slit.
Arias initially denied her involvement, then blamed the attack on masked intruders. Two years after her arrest, she claimed she acted in self-defense.
On April 7, a tweet read: "He who tries to establish his point by much yelling shows that his reasoning is weak." Another tweet, posted on the account on April 5, likely takes a shot at Martinez's animated and fiery style: "Hmm ... Anger Management problems anyone?" the tweet read.
"Those afflicted with Little Man's Syndrome taint society's perception of genuinely good men who happen to be vertically challenged," another tweet read, possibly taking a jab at Martinez's stature.
The Twitter account took a swipe at the cable network HLN, tweeting, "HLN is an acronym for Haters Love Negativity."
She also took aim at HLN anchor Nancy Grace, also a frequent guest on "Good Morning America," who accused Arias of giving the middle finger during the trial.
Arias' Twitter account shot back, tweeting, "Actually, Nancy, that finger was for you. Have a nice day."
The tweet has since been deleted.
Bering has been a constant presence at the Phoenix courthouse, showing up almost every day. Bering got to know Arias while incarcerated in 2008 on an accessory to arson charge.
Other tweets reflect on Arias' time away from the courtroom and her time in jail.
"God bless five-day weekends" was tweeted on March 7. Eight days later she tweeted, "No, I do not have a girlfriend. After everything I've been through it's amazing I'm not gay."
Bering spoke to ABC News in February and said the media were not being fair to her friend.
"I wish I could just say, 'Wait a minute ... that's not true,' you know?" she said.
Bering said that Arias was not the murderous monster the trial has portrayed her as.
"I find it really hard to believe what happened, knowing her," Bering said. "Never, ever have I seen her raise her voice, seen her yell, seen her do anything. So when I'm sitting there in court, it blows me away because I'm sitting there knowing the person that I know, seeing her and talking to her and see[ing] how much compassion she has."
The Twitter account is also promoting a website selling artwork that Arias did while in jail. The site claims to have sold four pieces, including a drawing of Frank Sinatra, for $1,075.
"I hear my website is beautiful. Too bad I can't see it," Arias' Twitter account tweeted Thursday.
The website claims "All pieces created after January 26, 2013, are authenticated with Jodi Arias' right thumbprint."
Arias' drawings were selling on eBay in January, including one of legendary actress Grace Kelly.
Arias was an aspiring photographer when she was arrested in July 2008.
On Thursday, jurors were allowed to ask questions through the judge about psychotherapist Alyce LaViolette's testimony and the 44 hours she interviewed Arias in jail.
LaViolette, a domestic violence expert, testified that Arias was a victim of domestic violence.
The questions ranged from how the witness can know that Arias wasn't lying to queries about Arias' claims that the victim abused her.
LaViolette returns to the witness stand Friday for more juror questions.
