State v. Yates (2007)

In State v. Yates, 161 Wn.2d 714, 772-773 (168 P3d 359) (2007), Yates argued that the trial court erred in allowing the State to use a large summary chart of the evidence regarding the 13 murders at issue. The Supreme Court noted that information regarding the evidence of each victim was posted on the chart after the evidence was introduced and found that "while the trial court has wide latitude in determining whether or not to admit demonstrative evidence, the court must make certain that the summary is based upon, and fairly represents, competent evidence already before the jury." Id at 772. The Court also noted that the chart was not, in itself, evidence, but was "only an aid in evaluating the evidence." Id. at 773 (9).
