Overview
- RCMP investigators testified they found no outside involvement and concluded the 2023 deaths of Christopher Duong, Janet Nguyen and their two sons were a murder‑suicide with no outstanding suspects.
- A shared “last will and testament” video was recovered from both parents’ phones and dated June 10, the day Duong was detained under the Mental Health Act and released hours later.
- Crime‑scene evidence placed all four in the same bed, with Duong suffering deep cuts and a box cutter nearby, Nguyen dead with an electrical cord around her neck, the boys positioned with teddy bears, no forced entry, and indications Duong was last alive.
- Duong’s phone contained searches such as “painless ways to kill oneself,” “where are the biggest arteries,” and queries about flights, with no messages suggesting he faced an external threat.
- Forensic experts reported THC in Duong’s blood and sedating levels of acetaminophen and doxylamine in Nguyen and the children, with causes of death identified as asphyxia for the boys, ligature strangulation for Nguyen and self‑inflicted cuts for Duong, while the inquest also heard concerns about child‑welfare contact timing and a psychiatrist’s call for a dedicated psychiatric hospital in B.C.
