The start of the 10th week of Robert William Pickton's murder trial in New Westminster, B.C., will be delayed until at least Tuesday because of a juror's illness.

The pig farmer from Port Coquitlam, B.C., is being tried on six counts of first-degree murder in the deaths of Sereena Abotsway, Mona Wilson, Marnie Frey, Georgina Papin, Brenda Wolfe and Andrea Joesbury.

Justice James Williams informed the B.C. Supreme Court on Monday that a member of the jury was not feeling well and suggested they adjourn for the day. The jurors agreed.

Williams suggested breaking for the day might be in everyone's best interest to prevent the illness from spreading.

"It occurred to me that one way of dealing with this would be to send everyone home for the day and whoever is not feeling well can have a day of rest and try to get past this," he said.

"There's a whole lot less chance that somebody else is going to be feeling unwell tomorrow or the days that follow."

Pickton was arrested in 2002. He faces a second trial at a later date on 20 more first-degree murder charges in the alleged slayings of other women, mostly sex-trade workers who went missing from Vancouver's Downtown Eastside.
