Lauren Heike murder: Not guilty plea entered for ex-convict accused of killing woman on Phoenix trail

An ex-convict accused of killing a woman who was attacked from behind and stabbed 15 times on a Phoenix desert trail could be facing a trial in January, authorities said Tuesday.

An attorney for Zion William Teasley, 22, entered a not guilty plea on his client’s behalf Tuesday, the day after a Maricopa County grand jury indicted Teasley on one count of first-degree murder.

The county attorney’s office said it’s reviewing the case to determine if prosecutors will seek the death penalty.

Phoenix police said the body of Lauren Heike, 29, was found April 29 near a hiking trail where she often walked about a half-mile from her home, but it’s believed she was killed the day before.

According to court documents, Heike had defensive wounds on her hands and arms from fending off her attacker, and she may have also been chased over or through a barbed wire fence.

Homicide investigators believe the attack was random and without provocation after Teasley allegedly followed her on the trail. A possible motive for the killing remains unclear.

"My heart goes out to the victim’s family and the pain they are experiencing losing their loved one in this manner," said County Attorney Rachel Mitchell. "Our office will work diligently to seek justice for Lauren and her family."
