The Integrated Homicide Investigation Team (IHIT) assumed conduct of the investigation. Supported by the Langley RCMP, the Combined Forces Special Enforcement Unit of British Columbia (CFSEU-BC) and the Integrated Forensic Identification Services (IFIS), IHIT investigators worked diligently to gather pertinent evidence from the scene.

He was also sentenced to, and six years for manufacturing of firearms, to be served concurrently. At the time of sentencing, Mr. Bos had spent two years in custody, credited as four years. He will serve a further 15 years in jail for these offences.
This outcome reflects the diligent work of our investigators and partners, says Sgt. Freda Fong of IHIT. While these investigations began separately, it was our strong partnerships that facilitated advancing both investigations. IHIT would like to extend our thoughts to the families of Mr. Mostat and Mr. Regnier. We hope that the conclusion of the court process provides them closure.
