509 S.W.3d 325
Tex. Crim. App.2017Background
- Appellant Jennifer Wolfe ran a licensed in-home daycare; seven-month-old Jack became unresponsive and was found to have a subdural hematoma, retinal hemorrhages (including retinoschisis), and brain swelling; imaging and surgery showed both new and older stages of intracranial bleeding.
- Wolfe was tried in a bench trial for first-degree-felony injury to a child; State relied principally on three medical experts who diagnosed abusive head trauma (AHT) based on a differential diagnosis of Jack’s constellation of injuries.
- Defense presented an expert who testified there is significant scientific disagreement about diagnosing AHT from the “triad” and emphasized Jack’s prior intracranial bleeding as a possible alternative cause of rebleeding with minimal or no trauma.
- Wolfe moved pretrial under Tex. R. Evid. 702/705 and Daubert/Kelly to exclude expert AHT testimony as unreliable; trial court heard testimony and literature, denied the motion, found Wolfe guilty, and sentenced her to five years.
- The court of appeals affirmed, limiting Wolfe’s appellate complaint to the general reliability of AHT diagnosis from the triad and holding the trial court did not abuse its gatekeeping discretion; a dissent argued the prior-bleeding issue was fairly included and raised serious reliability questions.
- The Texas Court of Criminal Appeals affirmed the court of appeals: it held the experts’ differential-diagnosis testimony about AHT based on Jack’s injuries was sufficiently reliable, and the court of appeals did not err in declining to consider the prior-bleeding argument that Wolfe chose not to brief on appeal.
Issues
| Issue | Plaintiff's Argument (Wolfe) | Defendant's Argument (State) | Held |
|---|---|---|---|
| Reliability of expert AHT testimony based on a constellation (triad) of symptoms | AHT diagnosis based solely on the triad (subdural hematoma, retinal hemorrhage, brain swelling) is unreliable because of ongoing scientific debate and potential "junk science"; should be excluded under Kelly/Daubert. | Experts used accepted differential-diagnosis methods; AHT is widely accepted in pediatric medicine and supported by peer-reviewed literature and professional organizations; testimony was probative and reliably applied. | Court held testimony admissible: applying Kelly factors, expert qualifications, literature, and differential-diagnosis methodology supported reliability; no abuse of discretion in admitting testimony. |
| Whether court of appeals erred by not considering Jack’s prior intracranial bleeding when assessing reliability | Wolfe argued the experts’ opinions were unreliable as applied to Jack because his prior brain bleeds could explain rebleeding or render the AHT diagnosis equivocal; this specific-history challenge was fairly included on appeal. | State and majority: Wolfe limited her appellate brief to a general challenge to AHT diagnosis from the triad; she failed to develop the specific prior-bleeding argument with citation/analysis, so the court of appeals reasonably declined to address it. | Court held the court of appeals did not err: it considered reliability as applied to Jack’s constellation of injuries but was not required to decide the unbriefed prior-bleeding contention; Wolfe failed to fairly present that issue on appeal. |
