128 A.3d 883
Vt.2015Background
- Defendant (Leo Pratt II) convicted of aggravated sexual assault of a 12-year-old relative based on victim T.B.’s letter, other statements, and forensic extraction from defendant’s cell phone.
- T.B. wrote a letter the night of the assault expressing fear; she later showed it to a friend and the school, which led to police/DCF involvement.
- At pretrial, State moved to admit T.B.’s out-of-court letter under V.R.E. 804a; defendant moved to exclude expert testimony about data extracted from defendant’s phone using Cellebrite.
- Trial court admitted the letter as sufficiently trustworthy under Rule 804a and admitted the forensic expert’s testimony under Rule 702 after a Daubert/Kumho-style reliability inquiry.
- Jury found defendant guilty; on appeal the defendant challenged (1) admission of the letter, (2) admission of the Cellebrite-based expert testimony, and (3) alleged coercion of the jury by court comment about resuming deliberations Monday. Court affirmed.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Admissibility of victim’s letter under V.R.E. 804a | Letter was a spontaneous disclosure to a trusted adult/peer; time, content, and circumstances show substantial indicia of trustworthiness | Letter alone is unreliable; no one witnessed writing so contents could be fabricated | Admitted: court’s findings (disclosure to trusted adult, age-appropriate writing, spontaneity, consistent statements, no coercion) supported admission under Rule 804a |
| Admissibility of forensic testimony on Cellebrite extraction (V.R.E. 702) | Expert had extensive training and experience, verified extractions by manual comparison and other software, and Cellebrite is widely used and testable; Daubert factors applied flexibly | Expert lacked knowledge of underlying programming, no error-rate evidence, and relied on popularity and training rather than source code understanding | Admitted: trial court did not abuse discretion; Daubert/Kumho factors applied flexibly to technical (non-novel) tool and foundational experience/testing sufficed; deficiencies go to weight not admissibility |
| Jury coercion by court remark about resuming Monday | N/A (State answered by upholding court’s neutral scheduling statement) | Court’s statement created time pressure and coerced verdict by implying deadline | No coercion: court plainly said verdict by 5:30 was "fine" if not reached, instructed jurors to take needed time, and merely informed them about scheduling if deliberations continued Monday |
