A B.C. man has been sentenced to 19 years in prison for the manslaughter of two men and for manufacturing guns.
With credit for time served awaiting sentencing, Justin Bos faces 15 years in prison.
Bos, 39, was convicted and sentenced in B.C. Supreme Court for the manslaughter with a firearm of Cody Mostat in March 2022, the manslaughter of Troy Regnier in August 2022 and for manufacturing of restricted firearms.
Mostat, 30, died at the scene in the 20400-block of 88 Avenue in Langley after police responded to a report of an unconscious man March 25, 2022.
Officers attempted life-saving efforts but to no avail.
On Aug. 27, 2022, police responded to a shooting outside a residence in the 16600-block of 19 Avenue in Surrey.
Officers arrived to find a man suffering from multiple gunshot wounds. Despite life-saving efforts by the officers, Regnier, 37, died as a result of his injuries.
Bos was identified as a suspect.
Bos was arrested Sept. 21, 2022 for the deaths of Mostat and Regnier.
The next day, Bos was charged with the second-degree murder of Mostat and he remained in custody as a result.
On March 12, 2024, Bos was charged with second-degree murder for the homicide of Regnier.
Bos was sentenced June 6 to a global sentence of 25 years, which was reduced by the court to 19 years after factoring in the principle of totality.
He was sentenced to 13 years in Mostat’s death to be served consecutively with six years for the manslaughter of Regnier.
He was also sentenced to six years for manufacturing of firearms for a separate investigation, also to be served concurrently.
At the time of sentencing, 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,” said spokesperson Sgt. Freda Fong of B.C.’s Integrated Homicide Investigation Team (IHIT).
“While these investigations began separately, it was our strong partnerships that facilitated advancing both investigations,” Wong said. “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.”
'A true Powell River boy'
Mostat grew up in Powell River and was remembered for his “kind heart and gentle soul.”
"Cody came into this world in Powell River General Hospital and grew up in this community a true Powell River boy. As such he enjoyed baseball, soccer and, of course, hockey,” reads his obituary.
According to a family member, he broke his foot and ankle while working as a welder when he fell off a scaffold.
"This injury led to his self-medication and ongoing struggles with addictions,” read the obituary.
'Laugh was like no other'
A funeral cost fundraiser by Regnier's sister said her brother's death tore at her family.
"My brother Troy was unlike any other," Megan Laura Taylor Mondini said. "He loved bigger than anyone I have ever known. He was caring and kind and always made sure you were OK before himself. He would do anything for anyone who was in need."
She said his life was not easy but that he made the most of what he had.
"His laugh was like no other and you could hear it across a room. He was smart and, as I like to say, the jack of all trades," she said. "He was my big teddy bear and my brat! He was a father, son, brother, uncle, nephew, friend and most importantly just a good guy to know!"
