David Bagby is a retired engineer, author, and prominent advocate for judicial reform, best known for his harrowing memoir Dance with the Devil and his tireless campaign to change Canadian bail laws. After the murders of his son Andrew and grandson Zachary, Bagby became a central figure in the push for Bill C-464, also known as "Zachary’s Bill," which significantly altered how Canadian courts evaluate bail for individuals accused of serious crimes when children are involved.
The story of David Bagby is one of profound personal loss transformed into a legislative legacy. While his name is inextricably linked to one of the most tragic true-crime cases in North American history, his work as an activist has had a lasting impact on the Canadian legal system, particularly regarding the protection of children during custody and bail proceedings. As of 2026, the reforms he championed continue to serve as a critical framework for judicial discretion in Canada.
The Catalyst for Change: The Andrew Bagby Case
To understand David Bagby’s impact, one must first understand the events that forced him into the public eye. In November 2001, David’s son, Dr. Andrew Bagby, was found dead in a park in Pennsylvania. The primary suspect was Dr. Shirley Turner, a woman with whom Andrew had a brief and tumultuous relationship. Shortly after the murder, Turner fled to Newfoundland, Canada, where she revealed she was pregnant with Andrew’s child.
This set the stage for a protracted legal battle that would expose significant flaws in the Canadian justice system of the time. David and his wife, Kathleen, moved from California to Newfoundland to be near their grandson, Zachary, and to ensure Turner faced justice. However, they found themselves in a legal nightmare where the rights of the accused appeared to overshadow the safety of the child.
The Extradition and Bail Conflict
The core of David Bagby’s frustration lay in the decisions made by the Newfoundland court system. Despite being charged with first-degree murder in the United States, Shirley Turner was granted bail by Justice Gale Welsh. The court’s reasoning was rooted in the Canadian Charter of Rights and Freedoms, which guarantees the right not to be denied reasonable bail without just cause.
David Bagby argued that the "just cause" was self-evident: a person accused of a violent murder posed a risk to the community and, specifically, to the child she was carrying. The legal system, however, operated on a presumption of innocence that, in this instance, did not account for the unique danger Turner posed to her own infant. This discrepancy became the focal point of David Bagby’s later activism.
The Tragedy of Zachary Bagby and the Call for Reform
In August 2003, while out on bail and awaiting extradition, Shirley Turner took the life of thirteen-month-old Zachary Bagby before ending her own life by jumping into the Atlantic Ocean. This second tragedy was seen by many as entirely preventable. For David Bagby, the grief was compounded by a sense of betrayal by the legal institutions he had trusted to protect his grandson.
The public outcry following Zachary’s death was immense. It led to the Turner Review and Investigation, an inquiry that criticized the social services and judicial handling of the case. David Bagby, however, was not content with mere apologies or reports. He sought a fundamental change in the law to ensure that no other family would have to endure a similar catastrophe.
"Dance with the Devil": A Father’s Voice
In 2007, David Bagby published Dance with the Devil: A Memoir of Murder and Loss. The book is a raw, unflinching account of the murders and the subsequent legal failures. Unlike many true-crime memoirs that seek to provide a sense of closure, Bagby’s writing was fueled by righteous anger. He criticized the "revolving door" of the justice system and challenged the moral foundations of legal technicalities that ignore common-sense safety.
The memoir served as a powerful tool for advocacy. It brought the technical failings of the Canadian Criminal Code to a general audience, making a complex legal issue accessible and emotionally resonant. The book, alongside the 2008 documentary Dear Zachary: A Letter to a Son About His Father (directed by Andrew’s friend Kurt Kuenne), galvanized public support for David Bagby’s legislative goals.
Zachary’s Bill: Amending the Criminal Code
The pinnacle of David Bagby’s work was the introduction and eventual passage of Bill C-464, commonly known as "Zachary’s Bill." Bagby worked closely with Members of Parliament, most notably Liberal MP Scott Andrews, to draft legislation that would address the specific loophole that allowed Shirley Turner to remain at liberty.
Technical Provisions of Bill C-464
Before the passage of this bill, Section 515 of the Criminal Code of Canada outlined the grounds on which a judge could deny bail. These were primarily related to ensuring the accused’s attendance in court (primary grounds), protecting the safety of the public (secondary grounds), and maintaining confidence in the administration of justice (tertiary grounds).
Bill C-464 amended these provisions to explicitly allow a judge to consider the safety and protection of the accused's minor children when deciding whether to grant bail. This was a landmark shift, as it recognized that a defendant might pose a specific threat to their own dependents, even if they were not deemed a general threat to the public at large.
| Feature | Pre-Bill C-464 Environment | Post-Bill C-464 (Zachary's Bill) |
|---|---|---|
| Primary Focus | Flight risk and general public safety. | Flight risk, public safety, and child protection. |
| Judicial Discretion | Limited specific language regarding the accused’s children. | Explicit authority to deny bail for the protection of the accused's children. |
| Burden of Proof | Often favored the accused's right to liberty in non-terror cases. | Enhanced weight given to the "best interests of the child" in bail hearings. |
| Extradition Cases | Treated primarily as administrative/procedural matters. | Greater scrutiny of the underlying charges' impact on domestic safety. |
| Status (2026) | Historical context of legal gaps. | Integrated into the standard Canadian Criminal Code. |
The Impact of Activism on Canadian Jurisprudence
The passage of Zachary’s Bill in 2010 was a rare example of a private citizen successfully influencing criminal law through sheer persistence and moral clarity. David Bagby’s activism forced the legal community to grapple with the limits of the presumption of innocence in cases involving extreme violence and vulnerable dependents.
By 2026, the "Zachary’s Bill" amendments have been cited in numerous bail hearings across Canada. Legal experts note that while the bill did not eliminate judicial discretion, it provided a necessary legislative "shove" to ensure that the safety of children is a primary consideration in the courtroom.
Criticisms and Legal Balance
It is important to note that David Bagby’s work was not without its detractors in the legal field. Some defense advocates argued that the bill could lead to "preventative detention" and undermine the Charter rights of the accused. However, the Canadian courts have largely reconciled these concerns by applying the amendments within the existing framework of the "tertiary grounds" for denying bail—where the release of an individual would shock the conscience of the community.
David Bagby’s response to such criticisms was always rooted in the reality of his experience. He argued that the "rights" of a dead child are non-existent and that the law must prioritize the living's safety over the theoretical liberties of those accused of heinous acts.
The Role of "Dear Zachary" in Public Awareness
While David Bagby provided the legislative drive, the documentary Dear Zachary: A Letter to a Son About His Father provided the cultural momentum. The film is widely considered one of the most emotionally impactful documentaries ever made. It transformed the Bagby family from a local news story in Newfoundland and Pennsylvania into a global symbol of the fight for justice.
For David Bagby, the film was initially intended to be a private home movie for Zachary to learn about his father, Andrew. When Zachary was killed, the film’s purpose shifted toward a public indictment of the legal system. The documentary’s success ensured that David’s message reached a demographic far beyond legal circles, creating the political pressure necessary to pass Bill C-464 through both the House of Commons and the Senate.
Life After the Bill: David Bagby’s Ongoing Influence
In the years following the enactment of the law, David Bagby remained a vocal advocate for victims' rights. Although he eventually stepped back from the intense public spotlight, his influence persists through the organizations and reform groups he supported. His story is frequently used in law schools to illustrate the intersection of victimology and criminal procedure.
In the current landscape of 2026, David Bagby is viewed as a pioneer of "Victim-Led Reform." His approach—combining personal narrative with specific, actionable legislative goals—has become a blueprint for other advocates seeking to change systemic failures. He demonstrated that while one cannot change the past, one can exert significant control over how the future handles similar crises.
Frequently Asked Questions
What exactly did David Bagby change in the law?
David Bagby was the primary catalyst for Bill C-464 (Zachary’s Bill). This legislation amended the Criminal Code of Canada to allow judges to refuse bail to a person accused of a serious crime if it is necessary for the protection or safety of that person’s children. This closed a gap where judges felt they lacked the specific authority to keep a parent in custody based solely on the risk they posed to their own child.
Why was Shirley Turner granted bail in the first place?
Under the Canadian legal standards of 2002, bail was often granted if the accused was not deemed a flight risk or a direct threat to the general public. Shirley Turner was a doctor with no prior criminal record, which led Justice Gale Welsh to believe she could be safely released into the community. The court failed to recognize the specific psychological profile of Turner and the extreme danger she posed to Zachary as a means of exerting control.
Is "Dance with the Devil" still relevant for readers in 2026?
Yes. Beyond the specific legal details, the book remains a definitive study on grief, the failures of bureaucracy, and the psychological impact of violent crime on survivors. It provides essential context for anyone studying Canadian law, victim advocacy, or true crime history.
How did David Bagby’s work affect the Canadian Charter of Rights?
His work did not change the Charter itself but rather influenced how its principles are applied. The Supreme Court of Canada has long held that bail is a right, but it is not absolute. Bagby’s activism helped define "just cause" for detention in a way that includes the protection of specific vulnerable individuals (children), rather than just the public at large.
Where can I find more information about the Bagby case today?
The primary sources remain David Bagby’s book Dance with the Devil and the documentary Dear Zachary. Legal researchers can also look up the Parliament of Canada's archives for Bill C-464 and the Turner Review and Investigation which provides a comprehensive breakdown of the social and legal failures in the case.
Practical Recommendation for Researchers and Advocates
For those studying David Bagby’s legacy or seeking to apply his methods to other areas of judicial reform, it is essential to focus on the specificity of the remedy. Bagby did not simply ask for "justice"; he identified a specific section of the Criminal Code that had failed his family and worked with legislative experts to draft a precise amendment.
If you are a victim advocate or a law student, analyzing the legislative journey of Bill C-464 provides a masterclass in how to navigate the balance between civil liberties and public safety. David Bagby's life teaches that systemic change requires a combination of emotional honesty and technical precision. The enduring presence of Zachary's Bill in 2026 is a testament to the fact that dedicated individuals can, indeed, reshape the institutions intended to protect them.
