State of Iowa v. Earl Booth-Harris, 942 N.W.2d 562

Background

On Feb. 16, 2015 a shooting at a Burlington, Iowa park killed Deonte Carter; a witness (Donnell Watson) saw a masked shooter wearing a black stocking cap and later found a firearm at the scene.
Earl Booth‑Harris presented to an Illinois hospital the same day with a gunshot wound; police recovered .45 caliber evidence at his home linking casings to the scene.
Watson was shown photos three times: an initial array (including another suspect) produced no ID; a same‑day single‑photo showup of Booth‑Harris produced no ID; two days later two sequential photo arrays (double‑blind administrator, written admonition) produced identifications of Booth‑Harris with reported confidence climbing from ~50% to 100% after officer interaction.
Booth‑Harris moved to suppress the identification as unduly suggestive and unreliable; the district court denied suppression, and the jury convicted him of first‑degree murder. The court used ISBA Criminal Jury Instruction 200.45 on eyewitness ID without defense objection.
The court of appeals affirmed; Booth‑Harris sought further review arguing (1) due process violation from the photo procedures and (2) ineffective assistance for counsel’s failure to request updated, science‑based eyewitness ID jury instructions.
The Iowa Supreme Court (majority) affirmed denial of suppression, declined to alter the Manson/Biggers two‑step test or to fault counsel for not requesting a Henderson‑style instruction; Justice Appel dissented urging state‑constitutional departure and reversal.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Admissibility of out‑of‑court photographic ID (due process — suggestiveness/reliability)	State: photo procedures (double‑blind arrays with admonition) were not impermissibly suggestive and, under Biggers factors, the ID was reliable	Booth‑Harris: single‑photo showup and repeated exposures, officer prompting, stress/weapon focus, and witness intoxication produced undue suggestiveness and a substantial likelihood of misidentification	Court: denied suppression — procedures not impermissibly suggestive; Biggers five‑factor analysis showed sufficient reliability; issues of weight and credibility for jury
Whether Iowa should change constitutional test for eyewitness ID (incorporate system/estimator variables or abandon second step)	State: follow federal precedent (Manson/Biggers); social science may inform evidence rules but not constitutional admissibility	Booth‑Harris: scientific consensus on estimator/system variables requires a new, more protective state‑constitutional standard	Court: declined to alter stare decisis; retained two‑step Manson/Biggers framework and left reforms to rules/instructions/evidence process
Ineffective assistance for failing to request modern, science‑based jury instruction on eyewitness ID	State: counsel not deficient; ISBA Instruction 200.45 fairly states law; research unsettled so no clear merit to object	Booth‑Harris: counsel should have requested Henderson‑style instruction explaining system/estimator variables; failure was prejudicial given centrality of ID	Court: counsel not constitutionally deficient; uniform instruction not shown to misstate law; studies show mixed effects for detailed instructions, so no Strickland prejudice proven
