People v. Atherton, 940 N.E.2d 775

Atherton charged Oct 14, 2005 with one count of predatory criminal sexual assault of a child; a second superseding indictment added a second count alleging contact with Ariana's anus; conduct alleged between Sept 8 and Nov 30, 2002.
Hearsay evidence from Ariana's statements to her stepmother admitted under section 115-10 after a hearing, with a Frye hearing request denied later.
Trial run Oct 20–27, 2008; Ariana testified about abuse; companion witnesses included Ariana’s mother Julianna, Jennifer O., and a nurse; DCFS investigation preceded the trial.
Atherton was convicted on both counts and sentenced to consecutive 12-year terms (total 24 years); he appealed on eight issues alleging sufficiency, voir dire, section 115-10 constitutionality, syndrome evidence, ineffective assistance, IPI 3.15, cumulative error, and Crime Stoppers fine.
The Illinois appellate court affirmed in part and vacated in part, notably vacating the Crime Stoppers fine and addressing the syndrome evidence and Rule 431(b) issues along with other challenges.
Key procedural posture included the court treating the sufficiency challenge under Collins standard and addressing Crawford v. Washington implications for section 115-10 and cross-examination of Ariana.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Sufficiency of the evidence on anus contact	State asserts Ariana's testimony supports penetration.	Atherton argues insufficient proof of contact with Ariana's anus.	Sufficient evidence; Ariana testified penis entered anus, supporting conviction.
Rule 431(b) compliance during voir dire	Rule 431(b) principles were properly covered via questions on difficulties and willingness to follow instructions.	Trial court failed to specifically address each Zehr principle.	No reversible error; questions complied; forfeiture aside, no plain-error impact.
Constitutionality of section 115-10 post-Crawford	Statements admitted under 115-10 were admissible because Ariana testified and was cross-examined.	Section 115-10 unconstitutional under Crawford.	Crawford not applicable here; reliance on Johnson; statements proper.
Admission of child-sexual-abuse-accommodation syndrome evidence	Syndrome evidence helpful to explain child behavior after abuse.	Evidence not scientifically established; potential prejudice.	Admissible; Frye not required; Young qualified; testimony within discretion; weight for jury.
IPI Criminal 4th No. 3.15 identification instructions	Not necessary as identity not in dispute; mother identified defendant; no error in omitting 3.15.	Instruction needed to address Ariana’s inability to identify in court.	No error; lack of necessity given evidence and cross-examination.
