Murders of Andrew Bagby and Zachary Turner

Shirley Turner: Background and Behaviour

Shirley Jane Turner was born on January 28, 1961, in St. Anthony, Newfoundland, the daughter of a U.S. serviceman and a local woman. Raised primarily in Wichita, Kansas, she moved back to Newfoundland with her mother after her parents separated. Turner enrolled at Memorial University of Newfoundland in St. John's in 1980, aiming for a medical career. Her personal life was marked by instability, including two marriages and three children from those relationships. A 1993 report to Newfoundland social services alleged she physically and emotionally abused two of her children, though the case was closed without interviewing her. Turner completed her medical degree in 1998 and began residencies at teaching hospitals across the province. Her professional conduct was severely criticized by supervisors, with one later describing her as a manipulative, guiltless psychopath who lacked commitment and became hostile when confronted.

Turner's behaviour extended into dangerous obsessions. In 1996, she began a relationship with a man thirteen years her junior, Miles Doucet. After he ended the relationship and moved away, she stalked him across provinces and states, culminating in a 1999 incident in Pennsylvania where she attempted suicide outside his apartment after ingesting drugs. She was found wearing a black dress, carrying roses and suicide notes. This pattern of fixation, manipulation and volatility foreshadowed the events that would follow with her next partner, Andrew Bagby. Turner's ability to present a charming facade while concealing her instability played a significant role in how she was later perceived by legal and social service authorities.

The Murder of Andrew Bagby

Andrew David Bagby was a 28-year-old American medical student from Sunnyvale, California, studying at Memorial University. He began dating Shirley Turner in early 1999. After Bagby graduated in May 2000 and began a surgical residency in Syracuse, New York, they attempted a long-distance relationship while Turner worked in Iowa. The relationship deteriorated due to Turner's possessive behaviour. In October 2001, she falsely claimed to be pregnant with Bagby's child. After a confrontational visit to Bagby in Latrobe, Pennsylvania, where they argued about his new girlfriend, Bagby ended the relationship on November 3, 2001, and put her on a plane back to Iowa.

Undeterred, Turner made three calls to Bagby's residence on November 4. That afternoon, she began a 16-hour, 1,523-kilometre drive from Iowa to Pennsylvania with a Phoenix Arms HP22 handgun and ammunition in her vehicle. In the early hours of November 5, she confronted Bagby at his home. Bagby arrived at work agitated and told his supervisor, Dr. T. Clark Simpson, about her appearance but dismissed advice to avoid a private meeting. Bagby's body was discovered the next morning in Keystone State Park. He had been shot five times in the face, chest, buttocks and back of the head. Evidence quickly pointed to Turner. Cell phone and internet records placed her in Latrobe, contradicting her alibi. A box of condoms in her Iowa apartment matched one Bagby purchased, and MapQuest directions to Latrobe were found. Ballistics linked unspent rounds from her firearm lessons to the scene. By the time U.S. authorities obtained an arrest warrant, Turner had fled to Canada.

Extradition, Bail and the Birth of Zachary

Turner abandoned her Iowa apartment on November 12, 2001, and flew to Toronto, eventually resettling in St. John's with her eldest son. The Royal Newfoundland Constabulary, collaborating with Pennsylvania police, placed her under surveillance. On December 2, they seized her trash and discovered an ultrasound printout dated November 29, confirming she was pregnant with Bagby's child. Turner was arrested on December 12, the same day extradition proceedings began. At a bail hearing, Newfoundland Justice Gale Welsh released Turner, stating the murder charge was not a threat to the public at large and that she was presumed innocent. Turner posted CAD$75,000 bail with help from her psychiatrist, Dr. John Doucet, a former Memorial University co-worker. Her bail conditions included surrendering her passports, reporting weekly to police, and not contacting Bagby's family.

The pregnancy transformed the case into a complex custody battle. Andrew Bagby's parents, David and Kathleen Bagby, moved from California to St. John's to fight for custody of their grandchild. Zachary Andrew Turner was born on July 18, 2002. Turner initially refused to let the Bagbys see him, fearing they would kidnap him. Observers noted Zachary had poor attachment to his mother and preferred his grandparents. Turner was briefly returned to jail in November 2002 pending an extradition decision, but Justice Welsh released her again in January 2003, reiterating the presumption of innocence. This series of decisions kept Turner free and in custody of Zachary while she fought extradition to the United States to stand trial for murder.

The Murder-Suicide and Immediate Aftermath

On August 18, 2003, Zachary was scheduled to be in his mother's custody. That day, Shirley Turner purchased a prescription of lorazepam from a St. John's pharmacy. She mixed the drug into Zachary's baby formula, ingested a toxic dose herself, then strapped the unconscious infant to her chest with her sweater. She drove to the Foxtrap Marina and jumped from a fishing wharf into the Atlantic Ocean. Both Turner and Zachary drowned. A coroner determined the lorazepam rendered Zachary unconscious before death, meaning he did not suffer. Their bodies were discovered on a beach by a vacationing couple. The murder-suicide occurred just months after a judge had cleared the way for Turner's extradition to the United States, highlighting the catastrophic consequences of her release on bail.

Investigations, Inquiries and Systemic Failures

The tragedy prompted multiple investigations into the systemic failures that allowed it to happen. In May 2006, the College of Physicians and Surgeons of Newfoundland and Labrador found Dr. John Doucet guilty of professional misconduct for helping post Turner's bail. He was fined $10,000 and ordered to undergo psychiatric counselling. Doucet, who expressed disappointment with the verdict, would later die in 2026 in Nova Scotia. The most comprehensive review was the Turner Review and Investigation, released in October 2006 by Winnipeg-based coroner Dr. Peter Markesteyn.

Markesteyn's key findings included a systemic failure to assess Zachary's safety needs, with officials operating on a presumption of Turner's innocence and becoming more concerned with her welfare than the child's. He cited poor communication between social workers and managers, and noted that internal disagreements about the need for long-term intervention were not openly discussed. The report made 29 recommendations for reform, which the provincial government accepted. Child and Youth Advocate Darlene Neville echoed the conclusions, stating the tragedy was baffling and that Zachary was in his mother's care when he should not have been. The inquiry could not fully examine the bail process, though it raised serious questions about it, leading to calls for a separate justice system review.

• The inquiry found no ongoing assessment of Zachary's safety needs.
• Officials were more concerned with Turner's welfare than the child's.
• Poor communication and lack of critical analysis among social services were cited.
• The report contained 29 recommendations for systemic change.
• The provincial government accepted the report's conclusions.

Legislative Change and the Bagbys' Activism

Driven by their grief and determination to prevent similar tragedies, David and Kathleen Bagby became vocal advocates for legal reform. David Bagby authored a 2007 memoir, Dance with the Devil: A Memoir of Murder and Loss, detailing the case. Their advocacy culminated in federal legislative change. On October 23, 2009, Liberal MP Scott Andrews introduced Bill C-464, known as "Zachary's Bill." The bill amended the Criminal Code of Canada to allow courts to consider the protection and safety of a child when making bail decisions for a person charged with a serious offence. The bill received unanimous support in the House of Commons and from Liberal Senator Tommy Banks, and was signed into law by Governor General David Johnston on December 16, 2010. Andrews stated the law gave the Bagbys a sense that their cries were heard and would help ensure such a tragedy never happened again.

Cultural Impact: The Dear Zachary Documentary

The story reached a global audience through the powerful 2008 documentary film Dear Zachary: A Letter to a Son About His Father. Directed by Kurt Kuenne, a close childhood friend of Andrew Bagby, the film began as a video memorial for Zachary to learn about his father. After the murder-suicide, it evolved into a searing chronicle of the case and the Bagbys' fight for justice. The film incorporates home movies, interviews with Bagby's family and friends, and footage of Zachary in Newfoundland. Released on October 31, 2008, by MSNBC Films and Oscilloscope Laboratories, it aired on television across North America and on the CBC in Canada. The documentary elicited an overwhelming public response, with many viewers reporting it changed their lives and prompting them to contact lawmakers. It serves as a powerful record of the human cost of systemic failure and a catalyst for public awareness about bail and child protection issues.

Key Figures and Their Roles

The case involved numerous individuals whose actions and decisions shaped its tragic outcome. Shirley Turner was the perpetrator, a physician whose history of manipulation, stalking, and professional misconduct preceded the murders. Andrew Bagby was the initial victim, a promising medical resident murdered by Turner. Zachary Turner was the infant son of Bagby and Turner, killed at 13 months old. David and Kathleen Bagby were Andrew's parents, who moved to Newfoundland to fight for custody of Zachary and became leading advocates for legal reform. Justice Gale Welsh was the Newfoundland judge who granted Turner bail twice, citing the presumption of innocence. Dr. John Doucet was Turner's psychiatrist who helped post her $75,000 bail and was later found guilty of professional misconduct. Dr. Peter Markesteyn was the coroner who conducted the independent review, authoring the critical 2006 report. Kurt Kuenne was Andrew Bagby's friend and the director of the Dear Zachary documentary. Scott Andrews was the Liberal MP who sponsored Zachary's Bill in Parliament. The involvement of these people across the medical, legal, judicial and social service systems shows how many different parts of the system failed.
