State v. Wall, 460 P.3d 1058

Background

Johnny Brickman Wall and Uta von Schwedler divorced in 2006; post-divorce Wall harbored strong animus and disputed custody with motive to harm.
On Sept. 27, 2011 Uta was found dead in her bathtub with cold water running; the scene showed signs of a violent struggle (blood pools, disturbed bedroom, defensive wounds) and indicators inconsistent with a lone overdose.
Autopsy: drowning as cause of death, near-lethal Xanax level with no pill remnants in stomach, defensive wounds, neck hemorrhages and petechiae consistent with strangulation; medical examiner ruled manner undetermined but said scene was more consistent with homicide.
Forensic testing: male DNA recovered under Uta’s fingernails (Wall could not be excluded) and DNA from a pillowcase included Wall as a possible contributor though some alleles were below the lab’s analytical threshold; some other comforter samples were inconclusive or excluded.
Wall gave inconsistent accounts of his whereabouts, offered shifting explanations after learning DNA testing was pending, had unexplained scratches, access to Xanax, and post-death statements/behavior the jury could view as consciousness of guilt.
Procedural posture: jury convicted Wall of murder after a four-week trial; Wall appealed raising (1) sufficiency of evidence, (2) admissibility of certain DNA evidence under Utah R. Evid. 702(b), and (3) ineffective assistance for failure to object to prosecutor’s closing remarks about DNA.

Issues

Issue	Plaintiff's Argument (State)	Defendant's Argument (Wall)	Held
Sufficiency of the evidence to support murder conviction	Cumulative circumstantial evidence (blood patterns, defensive wounds, staged scene, male DNA under fingernails, motive, opportunity, inconsistent statements) permits reasonable finding of homicide and Wall’s guilt	Evidence equally or more consistent with suicide/accidental overdose; reasonable doubt exists	Affirmed — viewing evidence in light most favorable to verdict, a reasonable jury could find guilt beyond a reasonable doubt
Admissibility of DNA evidence (Rule 702(b))	Forensic lab methodology and policies (including treating below-threshold allele activity as detectable and re-testing) met the minimal threshold of reliability; admission proper	Lab’s inclusion of Wall as possible contributor based on alleles below analytical threshold was unreliable and should have been excluded	Affirmed — district court did not abuse discretion; State met threshold showing of reliability; weight for jury
Ineffective assistance for failure to object to prosecutor’s DNA characterizations in closing	Prosecutor’s closing fairly argued the totality of evidence, including DNA and facts the medical examiner lacked when drafting his report	Prosecutor misstated/overstated DNA evidence; counsel should have objected, so failure was deficient and prejudicial	Affirmed — counsel’s choice to forgo objections was a reasonable tactical decision; objections would likely have been futile; no deficient performance shown
