How Debbie Dorian's Killer Escaped Police for Over 20 Years | 20/20: The After Show

Key Concepts

• Debbie Dorian Murder Case: The central focus of the story, involving the unsolved murder of a 22-year-old college student.
• Serial Predator: The perpetrator of Debbie Dorian's murder was also responsible for other sexual assaults.
• DNA Evidence: Crucial in solving the case, but its initial lack of a match prolonged the investigation.
• CODIS (Combined DNA Index System): A national database for DNA profiles, which did not initially contain the perpetrator's DNA.
• John Doe Arrest Warrant: A legal strategy used to stop the statute of limitations from expiring on sexual assault charges when the perpetrator's identity is unknown but their DNA is on file.
• Forensic Genetic Genealogy: An advanced DNA analysis technique that uses family trees to identify suspects, similar to its application in the Golden State Killer case.
• Jane Doe Survivors: Brave women who came forward to report assaults, providing critical DNA evidence and testimony.
• Victim Impact Statement: A statement made by victims or their families in court to describe the harm caused by the crime.
• "Monsters Among Us": The concept of individuals who appear ordinary but are capable of heinous crimes.

Summary of "2020 The After Show" - "I'm Going to Get You"

This episode of "2020 The After Show" delves deeper into the 2020 story titled "I'm Going to Get You," focusing on the tragic murder of 22-year-old Debbie Dorian and the nearly 20-year investigation that followed. Host Deborah Roberts and correspondent Juju Chang discuss the case, highlighting the victim's promising future, the challenges faced by law enforcement, and the pivotal role of survivor testimony and advanced forensic techniques.

The Tragic Loss of Debbie Dorian

Debbie Dorian, a bright economics graduate from Fresno State University with aspirations of becoming an audiologist, was found dead in her apartment in August 1996. Her father, Peter Dorian, discovered her lifeless body. Debbie was described as a "shining star," the life of the party, and deeply loved by her friends and family. Her dreams were tragically cut short by her killer.

The Pain of the Parents

The loss of Debbie has had a profound and lasting impact on her parents. Her father, who discovered her body, has understandably receded from public life. Her mother, Sarah Dorian, has been a determined advocate for justice, having made a promise to the lead investigator that they would not give up on her daughter's case. Sarah spoke about how her grief has "shape-shifted" over the years, planting pine trees the year Debbie was killed as a testament to the enduring pain.

The Investigation: A Two-Decade Pursuit

Law enforcement faced a significant challenge in identifying Debbie's killer. The initial investigation focused on individuals she had contact with, including a potential roommate. A man named Alvin, a registered sex offender, was initially investigated but was excluded by DNA. Maurice Dixon, a friend of Alvin's, became a person of interest due to his mention of duct tape, which was used to bind Debbie. While Maurice initially tested positive, he was later cleared.

The case remained unsolved for nearly two decades, with investigators testing 146 different individuals against the DNA samples found at the crime scene. The case never officially went cold, but progress was slow due to technological limitations at the time.

The Breakthrough: A Brave Survivor and Advanced Forensics

A significant turning point in the investigation came with the bravery of a young woman, identified as Beth, who was attacked by the same perpetrator between 1999 and 2002, after Debbie's murder. Beth, then 19, was riding her bike at night when the assailant pulled out of a street, grabbed her handlebars, and pulled a gun on her. Despite her terror, Beth defiantly told him, "I'm going to get you. You're not going to get away with this."

During the altercation, the perpetrator left a DNA sample on the ground. Beth, demonstrating remarkable presence of mind, circled around to avoid being followed home, then immediately contacted the police. This DNA sample, collected from Beth's assault, became crucial.

The DNA evidence from Beth's attack was a case-to-case match with the DNA found at Debbie Dorian's murder scene. This connection, combined with the advancements in DNA technology, allowed investigators to finally identify the perpetrator.

Forensic Genetic Genealogy and the Identification of the Killer

The case benefited from the development of forensic genetic genealogy, a technique that gained prominence with the Golden State Killer investigation. This method allows investigators to analyze DNA samples beyond the CODIS database by examining family trees of individuals who have voluntarily uploaded their DNA.

By using this technique, investigators were able to compile a family tree and identify a suspect living in the area who matched the profile. This led them to Nikki Stain, a 52-year-old married father of two who was active in the PTA and worked as a restaurant manager. Stain was described as a "monster among us," hiding in plain sight.

The Confrontation and Arrest

Investigators approached Nikki Stain at his workplace. During questioning, he denied any involvement and refused to voluntarily provide a DNA swab. However, investigators conducted a dumpster dive and recovered discarded items, including a razor, from which they obtained a DNA sample that matched the evidence from both Debbie Dorian's murder and Beth's assault.

Stain was found to have a "fantasy life," maintaining a fake Facebook profile under the name "Nikki Steel" with images of himself in glamorous scenarios.

Plea Deal and Justice for Victims

Nikki Stain ultimately pleaded guilty to 12 felony counts, including murder and multiple sexual assaults. This plea deal spared him the death penalty. Prosecutors insisted that Stain be charged with the sexual assaults, not just murder, to ensure that the crimes against Beth and other victims were officially on record. This decision was made to honor the victims and ensure their experiences were acknowledged.

The Enduring Impact and Legacy

The case highlights the perseverance of law enforcement, particularly lead investigator Vince Zavala, who vowed to Debbie's mother that he would not give up. The story also underscores the profound impact of trauma on survivors, with Beth describing how the assault "almost destroyed her life" but also how coming forward and testifying has been a healing process.

Sarah Dorian delivered a powerful victim impact statement in court, speaking in her daughter's voice and describing the life that was stolen from Debbie. The case serves as a testament to the bravery of survivors, the dedication of investigators, and the evolving capabilities of forensic science in bringing perpetrators to justice.

The episode concludes by emphasizing that Nikki Stain will spend the rest of his life in prison, offering a measure of justice for Debbie Dorian's family and the other victims. The story is a stark reminder of the "monsters among us" and the importance of never giving up on seeking justice for victims.
