Alexander was murdered in 2008 as he showered in his Mesa, Ariz. home. He was stabbed dozens of times, shot in the head, and his throat was slashed. Arias admitted killing Alexander, her former lover, in self-defense.
She reportedly converted to Mormonism due to her relationship with the slain man.
A Church of Jesus Christ of Latter-day Saints volunteer spoke with 12 News on the condition of anonymity, saying he has met with Arias in the Phoenix Estrella Jail to pray with her.
The man, 71, is described as being a “slender, soft-spoken Mormon” and said he has grown to feel compassion for Arias, according to report.

He also stated he is “hoping and praying” the jury acquits her of Alexander's murder.
Although the man said he has visited Arias at least 10 times, he told 12 News he has not done so since her trial began.
This week, Arias testified in her own defense, telling the jury on Monday that she once walked in on Alexander masturbating to photos of young boys. On Tuesday, the jury heard audio of graphic phone sex between Arias and Alexander, which appeared to embarrass Arias as she sat on the stand with her head in her hands while the explicit tape was played in the courtroom. Wednesday, the jury was read emails sent to Arias by Alexander, in which he called her a “slut,” a “whore,” and likened her to a “sex slave.”
Arias, 32, claimed the day of the murder she had been taking photos of Alexander, 30, in the shower, when she was hit on the back of the head. She said when she awoke Alexander was being killed by two masked intruders.

According to Arias' story, she was able to escape, but claimed she did not tell police about the incident because she was scared.
Later she admitted killing Alexander, but claims it was in self-defense.
If she is convicted of first-degree murder, she could face the death penalty.
