Twelve jurors have now been selected in the first-degree murder trial of Edmonton filmmaker Mark Twitchell, who is charged in the alleged life-imitates-art murder of Johnny Altinger.

The 12 individuals were chosen from 192 people who arrived at court on Monday morning after being summoned for jury duty.

Prospective jurors were asked a number of questions by Crown and defence lawyers to see how much each person may have heard about the case, which received international media attention at the time of the crime.

Some people were let go early. The elderly, those with health problems, and the spouse of a judge were excused.

Police allege Twitchell lured Altinger to a south-side garage in October 2008 and killed him. Investigators accuse the independent film producer of acting out his own film-script storyline.

Altinger mysteriously vanished on Oct. 10. His body has never been found.

On Tuesday, two alternates will be selected for the jury.

The trial is slated to start Wednesday and last until the end of April.

Seventy-two witnesses are slated to be called. It is expected media from outside Canada, specifically, American TV, will be in Edmonton for the start of the trial.
