Ron Calhoun was described as a giant in the charitable world who did so much for so many.

Last week, a judge upheld the guilty verdict and rejected a hearing to determine Arfmann's mental fitness at the time of the murder.

Justice Carol Ross ruled on Thursday that Oscar Arfmann should not face a hearing to determine whether he is not criminally responsible for Const. John Davidson's murder.

The only known video of Oscar Arfmann with a gun on the day of Const. John Davidson's death was played in court in June, but was released to the public Friday.

Oscar Arfmann was charged with first-degree murder for the killing of Abbotsford police Const. John Davidson in 2017.

No witness actually saw Arfmann pull the trigger, and defence made the case that someone else killed John Davidson with a different weapon. 

Lawyer Martin Peters told the B.C. Supreme Court in News Westminster that no evidence will be presented in his client's defence, effectively closing their case.

A statement from Oscar Arfmann last month that Crown said was an admission of guilt was also tossed out by evidence.

Const. Shawn Alton identified Oscar Arfmann as the man driving the suspect vehicle he rammed with his police cruiser to stop it from fleeing the scene.

"I'm in a car. If he stops and pulls his gun out on me I'm going to run him over. It's just that simple," said the witness in a 911 call recorded on his dash cam.
