State v. Jones, 790 S.E.2d 17

Background

Jones lived with the victims (two minor sisters) and their mother and sexually abused the girls from about 2004–2009; one victim reported over 100 incidents and one contracted an STD.
Jones was indicted on multiple counts of criminal sexual conduct and lewd acts; at trial the jury convicted him on one count first-degree CSC, one count second-degree CSC, and two lewd-act counts; other counts were acquitted.
The State proffered Shauna Galloway-Williams as an expert in child sex-abuse dynamics to explain delayed disclosure, disclosure processes, and nonoffending caregiver behavior; she had training and experience but did not interview the victims or prepare a case-specific report.
Jones objected pretrial and at voir dire, arguing the expert testimony was within jurors’ common knowledge, unreliable (insufficient proof of peer-reviewed support), improperly bolstered victims’ credibility, and was prejudicial/cumulative.
The circuit court qualified Galloway-Williams as an expert and admitted her general testimony (no case-specific credibility opinions); Jones was convicted and appealed claiming abuse of discretion in admitting the expert testimony.

Issues

Issue	Plaintiff's Argument (State)	Defendant's Argument (Jones)	Held
Admissibility — whether subject matter (delayed disclosure, caregiver responses) is beyond jurors’ ordinary knowledge	Expert testimony helps jurors understand child-victim behavior and caregiver responses not within lay experience	Testimony addresses matters jurors could understand without expert help; thus unnecessary	Court held subject matter is beyond ordinary juror knowledge and admissible (following State v. Brown)
Reliability (Watson prong — foundational support/peer review)	Expert relied on accepted literature, trainings, and professional practice; methods are used nationwide	Expert could not name specific studies at trial and thus testimony lacked demonstrated reliability/peer-review foundation	Court found the record (expert’s training, textbook, and testimony about peer-reviewed literature) sufficient; no abuse of discretion on reliability
Improper bolstering / credibility	Expert gave general behavioral explanation and did not opine on credibility or interview victims; testimony assists jury, not vouch for victims	Testimony functioned to corroborate and improperly bolster victims and the mother	Court held testimony did not improperly bolster because expert did not comment on veracity or interview subjects; distinguished cases where experts conducted forensic interviews
Prejudice / cumulative effect (Rule 403)	Probative value in explaining victim/caregiver behavior outweighs any prejudicial effect; testimony was not cumulative	Expert evidence was highly prejudicial and merely cumulative to victim testimony	Court held testimony was not cumulative or unduly prejudicial and admission did not substantially outweigh probative value
