Just because accused killer Robert William Pickton was prepared to engage in petty crime shouldn't bias jurors, the judge in the case told jury members Thursday.

As he concluded his review of evidence at Pickton's trial in B.C. Supreme Court in New Westminister, Justice James Williams informed the 12-member jury that it was to be their last night in their own beds for a while.

He said he would conclude his instructions on Friday with guidelines on how the jurors, who will be sequestered immediately, should handle their work.

"Tomorrow [Friday], the hard work is going to land squarely in your lap," Williams said.

For the jurors, it will mean long days sequestered — possibly 12-hour days — staying at a motel, unable to talk to friends or family, watched constantly by sheriffs officers to ensure they don't watch the news, read newspapers or are exposed to anything that could influence their decision.

Pickton, a Port Coquitlam pig farmer, is charged with first-degree murder in the deaths of Sereena Abotsway, Mona Wilson, Andrea Joesbury, Brenda Wolfe, Marnie Frey and Georgina Papin. He'll face another 20 murder charges at a later date.

He has pleaded not guilty to all charges.

Williams cautioned the jury several times on Thursday to be careful about being tripped up by details in the testimony.

Reminds jury of deal

He reminded jurors about a deal key Crown witness Andrew Bellwood made with Pickton to swap good tires on a truck for used ones to make some cash.

Williams told the jury the effect of the evidence was that Pickton was prepared to engage in criminal activities with Bellwood.

Through it the Crown intended to show that Pickton was comfortable enough with Bellwood to discuss confidential matters.

"I must caution you that you should not let the fact that Mr. Pickton was apparently proposing to commit a criminal offence cause you to assess the present charges against him unfairly and other than on the evidence that there is to prove them," Williams said.

Bellwood testified during the trial that Pickton told him about picking up sex-trade workers and killing them.

Regarding Lynn Ellingsen's testimony, the judge took the jurors through her chilling statement about seeing Pickton in his slaughterhouse, covered in blood, with a woman hanging from a hook.

Ellingsen had testified the woman had been picked up by Pickton earlier that same night from the Downtown Eastside.
