Roseau, Dominica — The defence team for the two American men convicted this week in the killings of Quebec filmmaker and entrepreneur Daniel Langlois and his partner, Dominique Marchand, said on Thursday it intends to lodge appeals challenging the verdicts.

Legal team signals multiple grounds of appeal

Ravi Rajcoomar, lead counsel for Jonathan Lehrer and Robert Thomas Snyder Jr., informed journalists that the defence will pursue several lines of appeal following the jury’s guilty verdicts in the Caribbean nation. The men have not yet been sentenced.

The convictions relate to the December 2023 discovery of the couple’s bodies in a burnt-out vehicle near the luxury ecotourism resort the pair operated in Dominica. Langlois was a well-known Canadian entrepreneur and filmmaker, recognised in Quebec for his work and investments in creative and environmental projects.

Background to the case and contested issues

Court filings seen by media detail a long-running dispute between Lehrer and Langlois centered on access along a public road that crossed private property and provided a route to the resort. That dispute, according to documents and reporting, predates the violence by several years and has been a feature of litigation and tension between the parties.

The trial, held in Dominica, concluded with a jury finding both men guilty of murder. The defence’s immediate announcement of appeals suggests the case will return to the courts for further review, potentially prolonging the legal and diplomatic attention surrounding the matter.

  • Victims: Daniel Langlois and Dominique Marchand
  • Accused: Jonathan Lehrer and Robert Thomas Snyder Jr.
  • Location: Bodies found in a burnt-out car near the couple’s resort in Dominica
  • Status: Convicted; sentencing pending; defence to appeal

Implications for sentencing and appeals

The timing of appeals can affect sentencing hearings and the enforcement of any penalty handed down by the court. An appeal may argue legal error, procedural unfairness, misdirection to the jury, or problems with the admissibility or evaluation of evidence — although the defence has not publicly detailed which grounds it will advance.

Sentencing has been deferred until after the defence files its appeal plans. That leaves the families of the victims, who are entitled to submit victim impact statements in many jurisdictions, waiting for closure while legal wrangling proceeds.

Cross-border and community consequences

The case has drawn attention on both sides of the Atlantic. For Quebec, the loss of a figure such as Langlois — whose work spanned technology, film and environmental ventures — has resonated among colleagues and in cultural circles. In Dominica, the crime and ensuing trial have spotlighted local judicial processes and security concerns at tourist properties.

Legal observers note that appeals in transnational cases can raise additional complexities, including questions about record-keeping, translation of documents, and coordination between jurisdictions. Any appeal will be conducted under Dominican law and procedures, although the outcome will be watched closely by Canadian observers and the families involved.

April 18, 2024 Jonathan Lehrer photographed leaving court after being denied bail on related charges
July 2026 Lehrer and Snyder convicted of murder; defence announces intention to appeal

Next steps and what to expect

Defence counsel will be required to file formal notices of appeal and specify the legal grounds on which they rely. That may include requests for a new trial or arguments that legal mistakes affected the verdict. The prosecution may respond and seek to uphold the convictions, and appellate courts will set timetables for submissions and hearings.

For the Langlois and Marchand families, the appeals process may extend the period before final legal resolution. For the public and for Quebec’s creative and business communities, the case will remain a focus of attention as proceedings continue.

Reporting on the appeals will follow developments as filings are made and court dates set in Dominica.
