A high-profile double murder case that captured international attention has reached a guilty verdict in Dominica, with local authorities highlighting the strength and reliability of the Caribbean nation’s judicial process. Robert Thomas Snider Jr. and Jonathan Scott Lehrer, both U.S. citizens, were found guilty of murdering Daniel Langlois, a prominent Canadian eco-resort entrepreneur, and his partner Dominique Marchand, in a ruling that closes one of the most closely watched criminal cases in the country’s recent history.
The victims’ charred remains were first discovered inside a burned-out vehicle in Dominica’s Soufrière region on December 1, 2023, weeks after they were reported missing to local authorities. With no direct eyewitness testimony, investigators built their case on a strong foundation of circumstantial evidence, linking the two accused men to the killings. Both defendants have remained in police custody since they were first charged in connection with the double homicide.
Following the delivery of the guilty verdict, Dominica’s Minister for National Security Rayburn Blackmore publicly praised the collaborative work of law enforcement, investigative teams, and prosecuting officials that led to the conviction. Blackmore specifically highlighted the leadership of Police Chief Lincoln Corbette, who personally oversaw the early stages of the investigation at the crime scene, as well as Deputy Commissioner of Police Jeffrey James, who served as the lead investigator on the case. The national security minister extended his commendation to the entire Criminal Investigation Department and the wider Dominican police force, saying the thorough probe demonstrated the high level of skill and professionalism within the country’s law enforcement ranks.
“I want to place on the record my commendation for the police,” Blackmore told reporters after the verdict. “This investigation demonstrates the level of excellence within the police force, and the caliber of talent that the police force has.”
Blackmore also recognized the contributions of the prosecution team, including Director of Public Prosecutions Sherma Dalrymple, lead prosecutor Keith Scotland, all additional legal staff working on the case, and the witnesses who came forward to testify during the high-court trial. He emphasized that the Dominican government prioritized allocating all necessary resources to the investigation and prosecution to ensure a full and fair pursuit of justice.
“The role of the ministry and that of the government was to provide the requisite resources to ensure that that matter was properly prosecuted,” he said. The minister added that the guilty verdict should send a clear warning to any individual considering engaging in violent or criminal activity within Dominica’s borders.
“I believe that the way we have to look at it is from the perspective of lessons learned from that experience and those who intend to do wrong, to have within their psyche you may be caught or you will be caught, and that the rule of law and the justice system in Dominica works,” Blackmore stated.
The case gained international media attention due to the status of the victims, who owned and operated a popular eco-resort on the island. Prior to the full High Court trial, Chief Magistrate Candia Carette-George rejected a no-case motion filed by the defense, ruling that prosecutors had presented sufficient prima facie evidence to require the two men to stand trial.
In addition to his double murder conviction, Lehrer faces separate criminal charges related to the alleged trafficking and unlawful importation of firearms. Those charges stem from an unrelated incident that occurred just days after Langlois and Marchand were killed.
