983 N.W.2d 231
Iowa2022Background
- Shortly after midnight on June 22, 2018, Jeffrey Stendrup entered a Colfax residence armed with a bat, chased and struck longtime friend and drug associate Jeremy McDowell during a dispute over stolen property and drugs.
- McDowell, a chronic methamphetamine user with coronary disease and emphysema, became unresponsive during or immediately after the assault and was pronounced dead hours later; toxicology showed 4,900 ng/mL methamphetamine.
- Police found a bloodied bat with Stendrup’s fingerprints; witnesses heard Stendrup yell “Where’s my shit?” while beating McDowell.
- Stendrup was tried in a bench trial, convicted of first-degree robbery (armed) and felony murder (robbery as predicate), and sentenced to life without parole plus concurrent terms; he also pleaded guilty to suborning perjury and tampering with a witness.
- Pretrial and at trial the district court limited the medical examiner’s (Dr. Thompson’s) direct cause-and-manner testimony under State v. Tyler, admitting a redacted autopsy report and allowing hypothetical-based testimony; the court of appeals considered that limitation an abuse of discretion but treated the hypothetical testimony as part of the record.
- On appeal Stendrup challenged (1) admissibility/weight of medical evidence, (2) sufficiency of evidence of intent to steal for robbery, (3) causation for murder (but-for/proximate), and (4) that the verdict was contrary to the weight of the evidence; the Iowa Supreme Court affirmed.
Issues
| Issue | State's Argument | Stendrup's Argument | Held |
|---|---|---|---|
| Admissibility of medical examiner testimony on cause/manner | Tyler should not control; Dr. Thompson’s opinions were based on objective medical and toxicological evidence and permissible (including hypotheticals). | District court should exclude or limit Dr. Thompson’s cause/manner opinions under Tyler because of reliance on nonobjective statements. | Court declined to overrule Tyler but held Tyler’s unique rationale did not apply here; limiting and redacting the autopsy was an abuse of discretion, though hypothetical testimony was properly admissible. |
| Sufficiency of evidence for first‑degree robbery (specific intent to steal) | Evidence (night entry, statements, asking for assistance, yelling for “my shit,” ambush with bat) supports intent to commit theft. | Attack was motivated by personal animus/retaliation, not intent to steal; no property was actually taken. | Substantial evidence supported specific intent to commit theft; convictions upheld. |
| Causation for felony‑murder (but‑for and proximate cause) | Dr. Thompson’s hypothetical opinion established that the assault combined with methamphetamine toxicity caused a fatal arrhythmia; assault was a but‑for factual cause and felony‑murder statute resolves scope/proximate concerns. | Methamphetamine toxicity alone could have caused death; State failed to prove but‑for causation. | Dr. Thompson’s testimony supported but‑for causation; eggshell/thin‑skull principle applies and felony‑murder removes scope‑of‑liability inquiry. |
| Weight of the evidence / new trial motion | District court properly weighed credibility and evidence at bench trial; no miscarriage of justice. | Verdict was contrary to the weight of the evidence given medical uncertainty, blood-scene inconsistencies, and unreliable witness testimony. | No abuse of discretion in denying new trial; appellate court will not reweigh evidence. |
