State of Iowa v. Waylon James Brown, 996 N.W.2d 691

At ~4:30 a.m., Jeremiah Jensen was chased near his apartment; Thomas White struck Jensen twice in the head with a baseball bat while Waylon Brown egged him on, shoved Jensen, and instructed White to take Jensen’s backpack and phone.
Surveillance video (≈38 seconds) captured Brown pursuing Jensen, White carrying a bat, White swinging twice, and the two leaving with Jensen’s backpack.
Jensen identified Brown and White to 911 and required medical treatment (13 staples). Detective review of video produced stills used at trial.
White invoked the Fifth Amendment at trial; he had earlier signed an affidavit blaming White and exculpating Brown. Brown testified he only shoved Jensen to stop him and did not know White had a bat.
Brown was convicted of first-degree robbery (dangerous-weapon alternative) and willful injury causing serious injury; sentenced to consecutive terms (25 years and 10 years). He appealed, arguing (1) insufficient evidence for robbery, (2) convictions should have merged, and (3) trial delay due to juror absences/COVID required a mistrial. The Iowa Supreme Court affirmed.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Sufficiency of evidence for first-degree robbery (aider/abettor)	State: Jensen’s ID, 911 call, and surveillance video show Brown aided/abetted an assault by a person visibly armed with a bat.	Brown: No proof he had intent to steal or knew White was armed.	Affirmed: Viewing evidence in State’s favor, testimony and video support intent and that Brown aided an armed assailant; instruction on aiding an armed assailant controlled.
Whether robbery and willful injury convictions must merge	State: The two offenses address different harms and have distinct elements; legislature did not intend single punishment.	Brown: The same assault (bat strike) served both offenses, so willful injury is necessarily included in robbery.	Affirmed denial of merger: Legal-elements test fails because willful injury requires proof of serious injury; statutes protect different dangers, so multiple punishments are permissible.
Motion for mistrial based on juror absences and COVID-related delay	State/Court: Short quarantines and pauses followed CDC guidance; no objective evidence of juror bias or that delay prejudiced Brown.	Brown: Nine-day delay risked juror memory loss, outside influence, rushed deliberations, or COVID fear affecting deliberations.	Affirmed denial of mistrial: Court properly balanced defendant rights and public safety, no objective evidence of prejudice; mistrial was not warranted.
