Man charged with manslaughter following fatal drug overdose
A man has been charged with manslaughter following a drug-related death that occurred in northeast Calgary in November 2025.
On Thursday, Nov. 27, 2025, two 16-year-old girls met with an acquaintance, a man in his 40s, in downtown Calgary. Following their initial meeting, the group attended the man’s residence in the 8300 block of Centre Street N.E., where it is believed drugs were consumed.
On the morning of Friday, Nov. 28, 2025, at approximately 7:25 a.m., the man discovered one of the girls was unconscious and called 911. Emergency responders arrived shortly after, but despite their efforts, the girl could not be revived.
A subsequent autopsy by the Office of the Chief Medical Examiner determined the cause of death was the toxic effects of carfentanil. The victim was identified as 16‑year‑old Jordynn ATKINS‑MATERI.
Following an investigation by the Calgary Police Service (CPS) Drug Investigations for Safer Communities (DISC) Team, and with Crown Prosecutor consultation, it was determined charges were warranted.
On Thursday, June 25, 2026, one man was taken into custody.
Steve Phillip Gilbert COLLINS, 40, of Calgary has been charged with one count of manslaughter in relation to this death. He will next appear in court on Monday, July 6, 2026.
“This is a heartbreaking loss, and we extend our deepest condolences to the victim’s family,” says Staff Sergeant Sean Gregson of the CPS Undercover Operations Unit. “Illicit drugs continue to have a devastating impact, particularly on vulnerable individuals in our community. This is exactly why the DISC Team was created – to ensure every overdose is thoroughly investigated and to target those responsible for trafficking these dangerous substances.”
This investigation comes as we recognize the International Day Against Drug Abuse & Illicit Trafficking today, June 26, 2026, a reminder of the ongoing impact of illicit drugs in our communities. This is the first time that the CPS has laid a manslaughter charge in relation to an overdose death.
About overdose investigations
In 2023, the CPS began an OverDOSE pilot project, which utilized drug investigators to maintain consistency in all overdose or drug-related death investigations. In 2025, the Service formalized this pilot project with the creation of the Drug Investigations for Safer Communities (DISC) Team.
The DISC Team targets drug traffickers responsible for selling substances causing overdose deaths, as well as the sale of illicit drugs online. The DISC Team works closely with our existing Drug Undercover Street Team (DUST) to conduct investigations.
