Jodi Arias, serving a life sentence in Arizona for the 2008 murder of her former boyfriend, has found a new outlet for expression and income: selling her artwork online.

Arias, who recently turned 44, maintains an online presence through a website and Instagram account managed by her family. While her website states she’s not accepting commissions, Arias recently completed a painting of a cow after a special request. She shared on Instagram that a prison guard took particular interest in the piece’s progress.

The convicted murderer’s artwork commands significant prices. An original acrylic painting titled “Beyond the Horizon” is listed at $2,500 on her website. Prints range from $28 to $39, and a set of collectible postcards is available for $34.95.

Arias was convicted of first-degree murder in the death of Travis Alexander, who was found in his Mesa home with 27 stab wounds, a slit throat, and a gunshot wound to the head.
