A man has pleaded not guilty in the homicide case of a Halifax teenager.

The province’s prosecution service says the man who was a youth at the time of the murder of Devon Marsman is charged with obstruction of justice and accessory after the fact.

The suspect’s name is under a publication ban.

Sixteen-year-old Marson went missing in February 2022 in Spryfield.

In June of that year, his case was treated as a suspicious disappearance and was part of the Nova Scotia’s major unsolved crimes reward program.

However, in September 2024 police announced Marsman was a victim of a homicide and human remains found were sent to the province’s medical examiner to be identified.

Police confirmed in March; they belong to Marsman.

Four others are facing charges in the case.

Forty-year-old Mark Douglas Robert Doyle has been charged with accessory after the fact to murder.

Chelsey Herritt, 26, faces charges including accessory after the fact to murder and indignity to human remains.

Emma Maria Meta Casey, 23, faces charges including accessory after the fact to murder, indignity to human remains and obstructing justice.

Treyton Alexander Marsman, 26, is facing second-degree murder charges, indignation to human remains and obstructing justice.

Police continue to keep Devon’s family and friends in their thoughts.
