Halifax Community Gathers to Mark Devon Marsman’s 21st Birthday, Renew Calls for Justice
On October 7, loved ones gathered in Halifax to celebrate what would have been Devon Marsman’s 21st birthday and demand justice. Marsman went missing at age 16 in February 2022. His cousin Treyton Marsman and four others were charged in 2024, with a final trial set for March 2027.
On October 7, family and community members gathered at the basketball court on Romans Avenue in Halifax’s west end to celebrate what would have been Devon Marsman’s 21st birthday and renew calls for justice in his murder case.
Devon Marsman was 16 years old when he went missing in February 2022 after attending a party with his cousin, Treyton Marsman, and another boy. From the beginning, Marsman’s mother, Theresa Gray, maintained that her son’s cousin was responsible for his disappearance.
On Sept. 17, 2024, police announced they had found Marsman’s remains and charged Treyton Marsman with second-degree murder, indignity to human remains, and obstruction. Later in 2024, authorities charged four additional people: Emma Maria Meta Casey, Chelsea Herritt, Mark Douglas Robert Doyle, and the other boy who attended the party with Marsman. Because the other boy was a youth at the time of the alleged crime, his identity is protected under the Youth Criminal Justice Act.
Casey, Herritt, and the youth each face multiple charges, including indignity to human remains. Doyle faces one count of accessory after the fact to murder.
Due to an all-encompassing publication ban, Global News cannot provide updates on legal proceedings until the jury is sequestered for the final trial, which is set to begin in March 2027.
Social justice activist DeRico Symonds is leading a project to dedicate the Romans Avenue basketball court, where Marsman often played, in his memory. At a regional council meeting on Sept. 29, it was announced that Devon’s name, along with seven others, was approved without debate to be reserved for application to a municipal asset.
