Long suspected of murder, she confessed but avoided prison

Twice-Convicted Murderer

FLAGSTAFF, Ariz. (AP) — There was no shortage of tips about who killed Pamela Pitts, a rowdy but compassionate 19-year-old whose body was found burned beyond recognition in a pile of trash in 1988.

A Satanic cult. A drug dealer. A cowboy. An ex-lover. A guy nicknamed “Halftrack.” Or maybe it was an overdose at a spot in central Arizona where people went to party.

It would take more than 30 years, some prison calls and an eyebrow-raising plea deal before a convicted murderer would confess and the mystery would partly be solved. But in a shocking twist, a court recently agreed Pitts’ killer wouldn't spend any more time behind bars.

Over the years, investigators couldn't pin down the evidence they needed to arrest anyone. The tips that poured in didn't add up. The slaying had stoked widespread fear about a killer on the loose around Prescott, a tourist town about 100 miles (160 kilometers) north of Phoenix.

And then the case went cold.

Yet, suspicion followed Pitts' roommate, Shelly Harmon, for the 20 years she spent in prison for fatally shooting her ex-boyfriend, Raymond F. Clerx. As her sentence was ending, police reopened the Pitts case and started monitoring Harmon's phone calls, eventually collecting 20 hours' worth of recordings, according to court documents obtained by The Associated Press.

One call gave prosecutors what they said they needed to connect Harmon to Pitts' killing. In it, Harmon's father said she never told him what actually happened.

“I had a moment. I had a huge moment,” Harmon replied.

Dennis McGrane of the Yavapai County Attorney's Office saw it as an admission of guilt.

“Like a sudden quarrel with the roommate," he said. “She wasn't planning it, but she did do it.”

Harmon's attorney, Dwane Cates, said statement could have referred to Clerx's death.

Clerx had wanted to end the relationship and was going to take their dogs. In a burst of anger, Harmon shot him as he lay on the roof of a car watching planes overhead. She stored his body in the trunk of her car for two weeks before the smell became overpowering and she dropped it in a mineshaft.

Before confessing, Harmon said, “I loved him. I was planning to spend the rest of my life with this man.”

With Pitts' death, Harmon's story changed over the years: She said Clerx was her alibi. She said she was never at the party spot outside t
