The trials for the brother and sister facing second-degree murder charges in the death of Roxanne Louie will be held separately.
Defence lawyer Don Skogstad said a judge has ordered two trials for his client Pier Robotti and co-accused Grace Robotti.
The pair are facing second-degree murder charges in connection to the January 2015 death of Louie. Both are in their 60’s.
The body of Louie, a 26-year-old single mother from the Osoyoos Indian Band, was found in a remote location between Naramata and Chute Lake after going missing for several days.
Grace Robotti is Louie's son's great-grandmother.
The trial for Pier is now scheduled to start March 6 in Kelowna, with the trial for Grace to begin March 20. There will also be a media blackout for Pier's trial, Skogstad said to avoid tainting the jury pool for the second trial.
A voir dire, a trial within a trial to determine the admissibility of evidence, has been held for Grace in Kelowna in recent weeks.
