State of Iowa v. Lawrence Eugene Walker, 935 N.W.2d 874

June 2016: Lawrence Walker babysat his four-year-old niece (E.W.) and others; he took E.W. upstairs, removed clothing, put her on his lap, bounced her, and rubbed her genitals.
E.W. told her mother and an emergency-room sexual assault nurse examiner (Elsa Durr-Baxter) about the abuse; forensic testing found a sperm cell on an anal swab and foreign DNA on underwear/back (too weak for a match).
Dr. Barbara Harre (Child Protection Response Center) separately interviewed and examined E.W. ~18 days later; E.W. made inculpatory statements identifying Walker.
Walker gave a recorded confession to police admitting the touching; he was convicted of second-degree sexual abuse and lascivious acts with a child.
On appeal Walker raised three evidentiary issues: (1) exclusion of evidence about the victim’s brother (J.W.); (2) admission of Dr. Harre’s hearsay testimony recounting E.W.’s identification of Walker; and (3) ineffective assistance for failing to object to nurse Durr-Baxter’s hearsay and eliciting additional hearsay on cross.

Issue	State's Argument	Walker's Argument	Held
1) Exclusion of evidence about J.W. (victim’s 8‑yr‑old brother)	Evidence about J.W. was irrelevant or, if marginally relevant, properly excluded under rules 5.403/5.412 because speculative and prejudicial.	The evidence tended to show E.W.’s sexual knowledge or the perpetrator could be J.W., not Walker; therefore relevant and admissible.	Court: No abuse of discretion. Walker failed to show a prior sexual encounter or make an offer of proof; evidence was speculative and—absent timely 5.412 notice—properly excluded as irrelevant/unduly prejudicial.
2) Admission of Dr. Harre’s testimony recounting E.W.’s statements identifying Walker	Statements were admissible under the medical-diagnosis-or-treatment hearsay exception (Tracy test met).	Statements were not for medical diagnosis/treatment and thus inadmissible hearsay.	Court: Admissible. E.W.’s motive and the context met Tracy’s two-part test; eighteen‑day delay did not defeat medical purpose.
3) Ineffective assistance for failure to object to nurse Durr‑Baxter’s hearsay and eliciting hearsay on cross	N/A (State defends conviction).	Trial counsel’s failures denied Walker effective assistance and prejudiced the defense.	Court: No Strickland prejudice. Record shows overwhelming evidence (confession, victim testimony, Dr. Harre’s statements, physical findings); any error was cumulative and not constitutionally prejudicial.
