A clear pattern is emerging in Colorado, where the trial of movie theater shooter James Holmes is expected to take months.

Prosecutors are weaving dry facts into a powerful story by punctuating technical testimony with the graphic and tragic recollections of survivors who lost limbs or loved ones.

Experts say this storytelling strategy could pay off at the end.

When jurors begin deliberating, the prosecution wants them to believe two things: That Holmes was sane when he killed 12 people and injured 70 at a Batman premiere, and that all the pain and suffering he caused requires a guilty verdict.
