Twelve people have been chosen to sit on the jury in the case of the man accused of killing a police officer two years ago.

Richard Kachkar is charged with first-degree murder in the death of Sgt Ryan Russell, who was killed when he was hit by a snow plow in January 2011.

More than 300 people were summoned as potential jurors. They were told that the trial is expected to last about two months, starting February 4th.

By Tuesday morning, twelve of them were chosen as jurors, two others as alternates.

Newstalk 1010 legal analyst Steve Skurka says it's very difficult to say someone is an ideal juror because the Crown and defence have such limited information about those summoned other than occupation and where they live.

"But really it's just an instinctive sense, is this person going to be fair in the case, is this the kind of person I want trying the case," Skurka says.

Skurka says the Crown and defence would have wanted to stay clear of anyone with an affiliation to the police or someone who has been influenced by all the publicity in the case.

"There's a lot of emotion in this case. There was a significant amount of publicity. The deceased in this case is a police officer, and so there are a number of concerns that are raised by that."

No matter how difficult the process is, Skurka says he has faith in the jury.

"Juries in this country continue to astound me. They've taken on the most challenging and difficult cases, Paul Bernardo and Robert Pickton come to mind," Skurka says. "In every case, they perform their task admirably and I have no doubt it'll be the case here too."
