Const. John Davidson

New Westminster: A judge found a man guilty of first-degree murder Thursday in the death of a police officer who had been investigating reports of a stolen vehicle in Abbotsford.

Justice Carol Ross of the B.C. Supreme Court found Oscar Arfmann guilty in the shooting of Const. John Davidson in November 2017.

The gallery was packed with dozens of police officers and members of Davidson’s family as Ross told the court that the Crown had proven “all the elements of the charge” against Arfmann.

Arfmann, dressed in a red sweatsuit, sat with his arms crossed and leaned back in his chair as Ross read her reasons for the judgment.

Defence lawyer Martin Peters filed a motion seeking further assessment of whether Arfmann is criminally responsible.

“As you have found him guilty, we now raise the issue of insanity,” Peters told the judge.

In reserving her decision in August, Ross advised the Crown and defence that they should be ready to make submissions about the potential role of Arfmann’s mental state if she found him guilty.

In closing arguments, the defence said Arfmann had no motive to kill Davidson and that the Crown’s case depended on conflicting witness accounts.

The prosecution said Arfmann ambushed the 53-year-old officer as he got out of his vehicle and shot him twice from behind.

Crown attorney Wendy Stephen told the trial that a man matching Arfmann’s description had stolen a vehicle two days earlier, shot at dealership managers who confronted him, left the area, then returned and killed Davidson to escape arrest.
