Halifax police confirm remains identified as Devon Marsman

Halifax police confirmed that remains discovered during the Devon Sinclair Marsman investigation have been positively identified as those of the 16-year-old.

Marsman was last seen alive on Feb. 24, 2022 and was reported missing from the Spryfield area of Halifax.

In September 2024, officers working on the case found human remains, which were forwarded to the Nova Scotia Medical Examiner for identification. Officials are not releasing the location where the remains were discovered due to ongoing court proceedings.

That same month, HRP announced that Marsman had been the victim of a homicide.

HRP has charged several individuals in connection with the case, including:

• Treyton Marsman, 26, has been charged with:
  • Second-degree murder
  • Indignity to human remains
  • Obstructing justice

Police said the accused is a relative of the dead 16-year-old.

• A 20-year-old man, who was a youth at the time of the murder, has been charged with:
  • Accessory after the fact to murder
  • Obstructing justice
• Emma Maria Meta Casey, 23, has been charged with:
  • Accessory after the fact to murder
  • Indignity to human remains
  • Obstructing justice
• Chelsey Herritt, 26, has been charged with:
  • Accessory after the fact to murder
  • Indignity to human remains

Officials said it was a “fair assumption” that at least one of the accused did something “terrible” to Devon after his death.

A GoFundMe says that Marsman‘s mom is the sole provider in his family and will have to miss work to attend the trial.

“She wants to make sure that the individuals responsible for taking her son’s life know that she will never let them live in peace,” the fundraiser reads. “She will always be there for him even though he is never coming home to her.”
