SUMMARY

2019COA160

No. 17CA0495, People v. Shanks — Evidence — Opinions and Expert Testimony — Testimony by Experts In this criminal appeal, a division of the court of appeals considers whether a trial court must conduct a Shreck hearing before admitting expert witness testimony analyzing historical cell site data. As an issue of first impression, but consistent with most federal courts, the division holds that the use of historical cell site data to determine the general geographic location of a cell phone is widely accepted as reliable and does not require a Shreck hearing. In so holding, the division distinguishes historical cell site analysis from the theory of granulization, which remains a source of controversy within the scientific and forensic communities.

Because the evidence offered at trial was within the bounds of reliable historical cell site data analysis, it was properly admitted.

The division also rejects the defendant’s contentions that the district court erred in denying his motion to suppress the victim’s out-of-court identification and in admitting the victim’s in-court identification; that the district court violated his rights to due process, to present a defense, and to a fair trial by disallowing certain evidence in support of and not instructing the jury on an alternate suspect defense; and that the district court erred by allowing reference to his nickname during trial.

Accordingly, the division affirms the judgment of conviction.

Opinion by JUDGE BROWN

Furman and Davidson*, JJ., concur

Announced October 24, 2019

Philip J. Weiser, Attorney General, Jillian J. Price, Senior Assistant Attorney General, Denver, Colorado, for Plaintiff-Appellee

Lauretta A. Martin Neff, Alternate Defense Counsel, Grand Junction, Colorado, for Defendant-Appellant

*Sitting by assignment of the Chief Justice under provisions of Colo. Const. art. VI, § 5(3), and § 24-51-1105, C.R.S. 2019.

¶1 Defendant Charles Jenson Shanks appeals from his conviction on two counts of kidnapping, two counts of burglary, and one count each of robbery, felony menacing, assault, and false imprisonment. He contends that the district court erred by (1) admitting expert witness testimony about historical cell site analysis without first conducting an evidentiary hearing; (2) admitting an impermissibly suggestive out-of-court identification and an in-court identification based thereon; (3) excluding his alternate suspect defense; and (4) allowing the use of his nickname, “Capone,” at trial. He also contends that the cumulative effect of these errors warrants reversal. We affirm.

¶2 Addressing an issue of first impression in Colorado, we conclude that expert testimony explaining how historic cell site data is used to provide a general geographic location of a cell phone at a given time may be admitted without first holding an evidentiary hearing on the reliability of the methodology.

I. Background

¶3 Shanks and his codefendant, William Cody, were charged with numerous offenses arising from the home invasion and assault of the victim.

¶4 The victim and Cody worked together and occasionally socialized outside of work. The victim supplied Cody with marijuana and the two men sometimes smoked marijuana together. On the night of the charged offenses, Cody called the victim to purchase some marijuana and arranged for his “sister,” codefendant Arianna Eastman, to pick it up for him.

¶5 The victim met Eastman outside his house for the transaction. When he turned to go back inside, a masked man, whom the victim later identified as Cody, and another unmasked man followed him and forced their way inside. The two assailants searched the apartment and beat up the victim before leaving with the victim’s equipment for growing marijuana.

¶6 A couple of days after this incident, the victim identified Shanks as the second assailant from a photo array. The victim identified Shanks again during trial.

¶7 A jury ultimately convicted Shanks as charged. The court sentenced him to twenty-eight years in the custody of the Department of Corrections.

II. Historical Cell Site Analysis

¶8 Shanks contends that the district court erred by admitting expert witness testimony analyzing historical cell site data without first holding a hearing to determine the reliability of the science behind such analysis. We disagree.

A. Standard of Review

¶9 We review the district court’s admission of expert testimony for an abuse of discretion and will reverse only when the decision is manifestly erroneous. See People v. Rector, 248 P.3d 1196, 1200 (Colo. 2011). “This deference reflects the superior opportunity of the trial judge to assess the competence of the expert and to assess whether the expert’s opinion will be helpful to the jury.” Id.

B. Applicable Law

¶ 10 A trial court determines the admissibility of expert testimony under CRE 702, which provides as follows:

If scientific, technical, or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education, may testify thereto in the form of an opinion or otherwise.

The inquiry focuses on “the reliability and relevance of the proffered evidence and requires a determination as to (1) the reliability of the scientific principles, (2) the qualifications of the witness, and (3) the usefulness of the testimony to the jury.” People v. Shreck, 22 P.3d 68, 70 (Colo. 2001); accord People v. Campbell, 2018 COA 5, ¶ 40. The court must also evaluate the evidence under CRE 403, ensuring that the probative value is not substantially outweighed by the danger of unfair prejudice. See Rector, 248 P.3d at 1200; Shreck, 22 P.3d at 70.

¶ 11 The court’s inquiry “should be broad in nature and consider the totality of the circumstances of each specific case.” Shreck, 22 P.3d at 77; accord Rector, 248 P.3d at 1200. Although the factors set forth in Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993), provide helpful guidance, a court need not consider any specific set of factors when determining the reliability of the proffered evidence. Shreck, 22 P.3d at 78.

¶ 12 Concerns about conflicting opinions or whether a qualified expert accurately applied a reliable methodology go to the weight of the evidence, not its admissibility. See Campbell, ¶ 42. “Such concerns ‘are adequately addressed by vigorous cross-examination,

presentation of contrary evidence, and careful instruction on the burden of proof.’” Id. (quoting Estate of Ford v. Eicher, 250 P.3d 262, 269 (Colo. 2011)).
