618 S.W.3d 887
Tex. App.2021Background
- On July 3, 2017, Dakota Wright robbed Jose Angel Soria at gunpoint; Wright was convicted of aggravated robbery and sentenced to 50 years.
- At trial the State introduced text messages and photos extracted from Wright’s phone using Cellebrite software.
- Detective Rex Kiser testified he connected the phone to a computer, ran Cellebrite, and copied readable messages/images to a memory stick; he gave minimal technical detail.
- Wright objected, arguing the State failed to establish a Kelly-style reliability predicate for the scientific technique used to extract the data.
- The trial court admitted the extracted data; on appeal Wright argued reversible error for lack of adequate reliability proof.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether the State was required to establish a Kelly-style reliability predicate before admitting Cellebrite-extracted phone data | Wright: The State failed to prove the validity of the underlying scientific theory and technique (Kelly prong 1), so the evidence was inadmissible | State: Extraction was a simple data-transfer that could be authenticated by lay testimony; no Kelly predicate or expert-level reliability proof was required | Court: Kelly (and Daubert/Nenno) did not govern here; extraction testimony was admissible as lay-authenticated evidence without a Kelly predicate; issue overruled and conviction affirmed |
