State v. Johnson, 860 N.W.2d 235

Background

Defendant Jesse Johnson, a prelingually deaf man, was accused by his then-seven-year-old stepdaughter, K.J., of multiple sexual offenses occurring when she was six; a recorded forensic interview and a February 6, 2012 police interview followed.
Investigator Ed Schulz conducted a ~2 hour 45 minute noncustodial, recorded interview at the police building with Katie Peterson, a Level III Certificate of Transliteration holder, serving as interpreter (blend of ASL and signed English). No Miranda warnings were given.
During the interview Defendant initially resisted but later admitted showing porn, allowing K.J. to touch his penis, and digitally penetrating her; he was not arrested immediately but an arrest warrant issued four days later.
Defendant moved to suppress the February 6 statements, claiming the interview was custodial and his confession involuntary due to interpreter errors and his deafness; the court held multiple evidentiary hearings and denied suppression.
Jury convicted Defendant of first-degree rape, aggravated incest, and sexual contact with a child; the trial court admitted expert testimony on delayed disclosure/grooming; Defendant appealed raising six issues including custody/Miranda, voluntariness, expert admissibility, double jeopardy, sufficiency, and alleged Brady violation.

Issues

Issue	Plaintiff's Argument (State)	Defendant's Argument (Johnson)	Held
Whether interview was custodial (Miranda required)	Interview was noncustodial: Defendant was told he was free to leave, read and initialed a written statement, door unlocked, not restrained.	Interview was effectively custodial because interpreter failed to meaningfully communicate right to leave; Defendant wouldn’t have felt free to go.	Affirmed: objective circumstances show noncustodial interview; a reasonable person would feel free to leave.
Whether confession was voluntary	Statements were voluntary under totality of circumstances: no threats, Defendant resisted for ~1 hour, had capacity to understand, and was not overborne.	Coercive interrogation techniques plus interpreter errors and cultural/communication vulnerabilities overbore Defendant’s will.	Affirmed: State met burden; confession voluntary.
Admissibility of expert testimony (Dr. Fiferman)	Expert was qualified and his general testimony on grooming/delayed disclosure would assist jury; Rule 702 allows general background testimony.	Expert lacked case-specific familiarity and thus shouldn’t have been allowed under updated Rule 702.	Affirmed: court did not abuse discretion; general expert testimony admissible and helpful.
Double jeopardy / multiple punishments	Separate legislative intent distinguishes rape and incest as distinct offenses; multiple punishments permissible.	Convictions punish same act twice (penetration).	Affirmed: legislative history shows distinct offenses; multiple punishments allowed.
