The accused takes the surprise at the bar of the trial on trial for the murder of B.C. police officer

The trial of an Alberta man accused of killing an Abbotsford police officer took a dramatic turn on Thursday, with the accused taking a surprise ride at the helm.

Oscar Arfmann faces a charge of first degree murder, with the Crown alleging that he would have fatally shot Const. John Davidson twice from behind, on November 6, 2017, while the agent was responding to a report about a stolen vehicle.

The strange twist created by a "voir dire" – an in-court hearing to determine the admissibility of new evidence.

First, Crown called a surprise witness at the bar, deputy sheriff Paul Cumming, who escorted Arfmann out of the prison box on Wednesday, following the testimony of a witness describing what the gunman was wearing.

Cumming said he heard Arfmann say, "I was wearing a black leather jacket and a Harley Davidson hat. What a dangerous fak I must be.

That's when the defense called Arfmann himself at the helm, where he confided in court that he often muttered to himself and that he actually said, "This is a Harley Davidson style leather jacket and that's for sure, because it was not me. "

Justice Carol Ross stated that it would take time to determine whether new evidence presented at trial would be accepted.

The plays came after the court heard the man who took the famous photo that allegedly represented Arfmann holding a rifle at the crime scene on the day of the shooting.

Mike McDonald, the car dealership's president accusing Arfmann of stealing a Ford Mustang, was the third witness to identify the suspect.

On Wednesday, the court heard another concession worker say that he and his boss had been confronted with Arfmann, after which the accused shot at the employee's van and fled.

On Thursday, Crown Attorney Theresa Iandiorio asked McDonald if he could identify the man at the meeting.

"I'm asking you to look around and see if you can identify this man in this room," Iandro said.

McDonald, who has a vision problem, asked permission to stand up and take a closer look at the back of the courtroom before heading to Arfmann.

"The man who confronted us and pulled the gun in our direction is sitting in the prisoner box in black shirt," McDonald said.

Arfmann's defense sought to question witnesses' memories of the day of the shooting, claiming that their memories may have been shaped by conversations with other witnesses or by media coverage.

The Crown has warned that it may attempt to file 911 appeals for these witnesses if the defense maintains this strategy.

The court has already learned that Arfmann had been arrested on the day of the shooting in a stolen Mustang with a rifle and knives on the inside.

Arfmann pleaded not guilty.

The trial is expected to last eight weeks and hear up to 30 witnesses.
