A 40-year-old Calgary man has been charged with manslaughter after a teen girl died from an overdose of carfentanil — an extremely potent synthetic opioid up to 100 times stronger than fentanyl and approved in Canada only for veterinary use on large animals.
On November 27, 2025, two 16-year-old girls met with an acquaintance at his residence in the 8300 block of Centre Street N.E. Drugs were consumed at the home.
The following morning, at 7:25 a.m. on November 28, 2025, the man discovered one of the girls was unconscious and called 911. Despite emergency responders' efforts, the girl — identified as Jordynn Atkins Materi — could not be revived. An autopsy determined carfentanil toxicity as the cause of death.
On Thursday, June 25, 2026, Steve Phillip Gilbert Collins was arrested and charged with one count of manslaughter. He is scheduled to appear in court Monday, July 6, 2026. Calgary police said this is the first time they have laid a manslaughter charge in relation to an overdose death.
