We Demand a Full and Independent Investigation Into the Yuba County Five Case

Who is Affected?

The families of the five young men—Gary Mathias, Ted Weiher, Jack Madruga, Bill Sterling, and Jackie Huett—have endured pain, confusion, and unanswered questions since 1978. Despite the discovery of four of their remains, no credible explanation has ever been provided. Decades of official silence, contradictory reports, and misleading media narratives have perpetuated this harm.

What’s at Stake?

Without a thorough, independent review, this case will remain buried under layers of negligence and likely corruption. This is not only about solving a mystery—it is about justice for the families, confronting abuses of power, and restoring public trust in institutions that have failed to uphold truth and accountability.

Why Act Now?

Recent media coverage, including Netflix’s Files of the Unexplained, has reignited public attention but recycled outdated narratives and omitted key facts, including uninvestigated suspects and official documents contradicting the “accidental death” theory. This narrative continues to harm the families and misinform the public.

An internal Yuba County Sheriff’s Office (YCSO) memorandum dated November 15, 2019, explicitly states that Gary Mathias is considered a victim of foul play but orders that this information not be communicated to his family. This document directly contradicts the theory promoted in recent media reports and was made public approximately one year later.

Systemic Failures and Evidence Suppression

Central Uninvestigated Suspect: Gary Dale Whiteley

Family Ties and Criminal History: Whiteley, Gary Mathias’s brother-in-law, has a documented history of violence, threats, and weapons offenses. In April 1979, he was arrested with two men for a brutal assault on Mary Perkins, pled guilty to assault with great bodily injury, and was sentenced to four years in prison.

Uninvestigated Confession: Civilian witness William J. Prater formally reported to YCSO on December 22, 1994, that Whiteley publicly stated, “I killed a girl,” and claimed responsibility for “the death of two of seven mentally disabled men in the hills 17 years ago.” Despite the chronological match (1978) and victim profile, no independent investigation was initiated.

Public Image and Institutional

Legitimacy: From the mid-1990s, Whiteley promoted a “redemption” image through A Changed Life Ministries Inc. and was invited to speak in law enforcement settings without full disclosure of his criminal history.

Media Use Without Context: In 2019, The Sacramento Bee cited Whiteley without revealing his criminal past, reinforcing a narrative that stigmatizes Gary Mathias and distracts attention from Whiteley.

Conclusion: Whiteley’s confession, criminal history, and institutional legitimization require immediate reevaluation as a priority line of investigation, including independent interviews, forensic review, and full documentary assessment.

Destruction of Files Following Transparency Law (SB 1421)

Court records for CRF73-18574 (People vs. Mathias, Gary Dale) show the official destruction of the physical file on July 23, 2019, just months after SB 1421 came into effect, mandating disclosure of police and court documents. Its replacement with an “Electronic File” dated July 24, 2019 raises questions about what was removed, the integrity of digital copies, and the intent behind destroying originals during a period of new legal transparency obligations.

Internal Document Altering Gary Mathias’s Status

The November 15, 2019 memo ordering that the family not be informed that Gary is a victim of foul play invalidates decades of official theories and mandates a full re-investigation under current standards.

Law Enforcement Officers with Compromised Credibility (Brady/Giglio)

Most officers involved in the case appear in the public Brady/Giglio database (including Lance James Ayers, Avery Blankenship, David McVey, Brian Bernardis, Lyndsey Deveraux, Henry Hull, Gary Finch, Larry McCormack, Harold Eastman, Robert Day, Dennis Forcino, Kenneth Mickelson). While inclusion does not indicate criminal conviction, it formally signals potential credibility issues as witnesses.

Documented Scene and Evidence Issues

Restricted-access discovery area (Soper-Wheeler/Sacramento Box) linked to the Whiteleys of Clipper-Mills: controlled routes and permits; not an open or easily accessible wilderness in winter.

Police and archival sources: LAPD (Joseph H. Schons arrest 9/01/1978), SAPD (1976 cases), IPD (Jon C. Schons armed kidnapping case), BPD (J. H. Schons vehicle theft), local Appeal-Democrat archives, and CPRA requests 2023–2025.

Incomplete Autopsies and Forensic Gaps: No histology, X-ray, or toxicology; hypothermia diagnoses lacking classical markers (e.g., Wischnewski ulcers); cervical fracture in Madruga unexamined for microfractures; amended certificates without new studies. Files show multiple serious deficiencies: no tissue sections, no microscopic slides, no formal histology report, only macroscopic descriptions and a beard/cheek sample request—far below the 1978 minimum histopathological standard. Contradictory documentation in Madruga and Huett’s files, missing radiographs, incomplete forensic anthropology, and DNA tests that were never conducted in the decades following exacerbate concerns. Requests for beard/cheek samples for time-of-death estimation were never accompanied by histology or methodological safeguards.

The scene is not available photographically; although the case files include notes indicating that photographs were taken, these images were never released and are not present in the files or elsewhere. The Mathias sneakers found in the trailer (previously referenced in the case files and recently appearing in a media report) cannot be definitively interpreted if homicide is considered (potential manipulation).

What We Demand

Independent, Public, Comprehensive Review of the Case

Full disclosure of all files from Yuba, Plumas, and Butte counties, including interviews, investigation notes, internal communications, and photographic/technical material.
New forensic analysis of all available evidence using modern techniques (histology, radiology, toxicology, DNA/anthropology).

Reexamination of previously ignored or dismissed leads and witnesses, prioritizing Gary D. Whiteley.

External Audit of YCSO

Administrative and legal review of obstruction of justice, evidence suppression/alteration, and abuse of power.

Independent investigation of the July 2019 file destruction after SB 1421, determining what materials were removed, whether digital copies were complete, and whether this constitutes obstruction or violation of preservation obligations.

Specific analysis of the November 15, 2019 memo and notification to the Mathias family.

Immediate Public Release of Key Documents

All memos instructing withholding of information from the Mathias family.
Any documents classified solely because Gary’s body was not found—a classification with no legal basis in missing persons cases—especially when the case remains formally ‘open’ but with no active investigative lines for decades.

Clarification of Gary Mathias’s Official Case Status

Formal declaration regarding whether the case remains open as a potential homicide and why this status and its implications were not clearly communicated to the family.

Legal Access and Family Protection

Unrestricted access to records.

Legal support to obtain documents, question witnesses, and participate in the review process without interference.

Investigation of Media Influence and Narrative Control

Examine relationships between YCSO and media outlets (ABC10, The Sacramento Bee, Netflix), including editorial agreements, omission of facts, and suppression of independent findings.

Public Media Corrections

Retractions and corrections where Gary Mathias or his family were defamed, providing space for families to present their perspective.

Reparations for the Families

Official apologies, public acknowledgment of investigative failures, and access to mental health and legal support.

Why This Matters

This is not only about five young men lost in the mountains. It is about a system that left a case unresolved for nearly 50 years by concealing evidence, denying context, and protecting individuals later deemed unreliable witnesses. Whiteley’s archived confession, criminal history, public legitimization in law enforcement settings, and the 2019 memo ordering that the Mathias family be kept uninformed all demand urgent action. Verified Brady/Giglio officers involved further underscore the need to audit the integrity of the original investigation and any media products that obscured these facts.

Documented scene and evidence issues—including restricted-access discovery areas, incomplete autopsies, missing photographs, and potentially manipulated evidence—reinforce the need for an independent forensic reevaluation.

Join the Movement

Sign this petition to demand transparency, accountability, and an independent investigation that does not repeat past errors. The families and the public deserve truth and justice.
