An Arizona district attorney's office is seeking the death penalty for Zion Teasley, the prime suspect in the Lauren Heike murder case.

Maricopa County Attorney’s Office (MCAO) confirmed the news in an email to Fox News Digital on Saturday.

Teasley, 23, pleaded not guilty to the homicide in May. He was indicted on a single count of first-degree murder.

Heike, 29, was fatally stabbed on a northwest Phoenix trail near her residence on April 28. Authorities say that she had around 15 stab wounds, along with injuries on her hands and forearms.

Based on evidence from the location, investigators believe she was chased over a barbed wire fence. Her belongings were scattered around the scene.

Teasley was arrested after police found video surveillance, cellphone evidence and DNA evidence that linked him to the crime.
