(AP) Two Oklahoma teenagers charged in the shooting death of an Australian baseball player in Duncan have pleaded not guilty and waived their right to a speedy trial. 18-year-old Michael Jones and 16-year-old Chancy Luna were arraigned Thursday in Stephens County District Court on first-degree murder charges in the shooting death of 22-year-old Christopher Lane. Judge Joe Enos set a trial docket date of August 18 for both teens. Lane was gunned down last summer as he was jogging. Another teenage defendant, 16-year-old James Edwards Jr., has agreed to testify against Jones and Luna if prosecutors reduce charges against him. He said last month that Luna shot and killed Lane from a car driven by Jones.
