TOPEKA, Kan. (AP) – About 800 people are expected to be summoned as possible jurors to hear the trial of a 51-year-old Oklahoma woman charged with killing her former husband and his fiancée.

Dana Chandler of Duncan, Oklahoma is charged with two counts of premeditated first-degree murder in the July 7th, 2002 slayings of 47-year-old Mike Sisco and 53-year-old Karen Harkness in Topeka.

The Topeka Capital-Journal reports that Chandler’s trial starts March 5th with jury selection. The trial is expected to last three weeks.

A court official says from the 800 prospective jurors called, 12 jurors and as many as five alternate jurors will hear the trial.
