Jodi Arias' Art May Depict Tanisha Sorenson, Travis Alexander's Sister

Accused murderer Jodi Arias may be using her victim's sister as inspiration for her artwork.

Arias, who prosecutors say killed her ex-lover Travis Alexander in a jealous rage, has already caught some flak for auctioning off her artwork in the wake of her high-profile trial.

Radar Online, however, has pointed out a startling aspect of Arias' art: Some of her drawings bear an uncanny resemblance to the sister of her alleged victims.

Tanisha Sorenson is Alexander's sister. Arias is accused of shooting Alexander in the face before stabbing him 27 times and slitting his throat. Arias admits she killed him, but said she did so in self-defense.

Earlier this month, Twitter page Justice4Travis reported that "nervous angry tweets" had surfaced, complaining that Arias' latest art series, "The Hat," appears to use Sorenson's likeness.

Facebook page "The State vs. Jodi Arias" noted that "Arias has been using [Sorenson] has her muse for years." In 2011, the group created a side-by-side comparison of Sorenson's photo and an image from Arias' "Zodiac" series.

The image, a colored-pencil drawing titled "Scorpio," shows a red-headed women who has the same large green eyes, sharp cheekbones and distinctively-shaped mouth as Sorenson.

On April 7, a tweet from a Twitter account purportedly controlled by Arias announced that "The Hat" series had been completed.

Though the series has not been put up for auction, according to the Daily Mail, the "Zodiac" series sold for $150 in January.

Sorenson has stated that she wants to watch Arias die.

"I know this might sound creepy," she told HLNTV in September, "but I hope to get to watch her die someday… the death penalty is what she deserves."
