## Facts

- On October 30, 2000, Thomas John Tuttle, an 18-year-old, had been drinking at a party and later went with a friend, Bereket Emehezian, to Tuttle’s grandmother’s mobile home in the Park View Trailer Court in Sioux Falls, South Dakota.
- Shortly after arriving, Tuttle and Emehezian argued and began shoving each other outside; neighbors came out to watch and eventually separated them.
- Police were called to the disturbance and arrived while Tuttle was outside near a parked car; after talking with people outside, officers initially found nothing unusual and prepared to leave.
- Tuttle’s grandmother then asked the officers to remove people from inside her mobile home, prompting the officers to enter.
- Inside the trailer, officers found Terrance Yellow Earrings (the boyfriend of Tuttle’s mother) leaning against the kitchen sink, bleeding heavily from multiple stab wounds; a recently washed paring knife was in the sink.
- Yellow Earrings had sustained eleven stab wounds. Others inside the trailer included Tuttle’s mother and Tuttle’s two uncles.
- No one in the trailer identified who stabbed Yellow Earrings. Police transported Yellow Earrings to the hospital and took Tuttle and the others present to the police station for questioning.
- Detective Thaddeus Openhowski interrogated Tuttle. During the questioning, Openhowski told Tuttle that his report could be written to “make things look good” for Tuttle, or that “I’m gonna have to write it up that you’re not cooperating, you’re being a real jerk about it.”
- Immediately after that statement, Tuttle responded, “Ok. I stabbed him. Whatever...” and confessed.
- The State charged Tuttle with aggravated assault under SDCL 22-18-1.1(2). Tuttle moved to suppress the confession as involuntary, but the circuit court denied the motion and admitted the confession at trial.
- At trial, Yellow Earrings was the only eyewitness who identified Tuttle as the assailant. The jury convicted Tuttle, and he appealed, challenging (1) the voluntariness ruling and (2) the refusal to give his requested cautionary jury instruction regarding custodial confessions.

## Issues

1. Whether, under the totality of the circumstances, Tuttle’s custodial confession was involuntary because it was induced by the detective’s threat to portray Tuttle as “not cooperating” and “a real jerk” if he did not admit guilt.  
2. Whether the trial court erred by refusing Tuttle’s requested cautionary jury instruction on how jurors should evaluate a custodial confession.

## Decision

- The Supreme Court of South Dakota held that Tuttle’s confession was involuntary and should have been suppressed.
- The court concluded that the detective’s statement functioned as an improper threat tied to Tuttle’s choice to remain silent, and that the threat plainly caused the confession.
- The court further held that the trial court erred by refusing Tuttle’s proposed cautionary instruction on custodial confessions.
- The conviction was reversed and the case was remanded for a new trial.

## Legal Principles

- A confession is voluntary only if it is the product of a free and unconstrained choice; courts evaluate voluntariness under the totality of the circumstances.
- Coercive police conduct is required for a confession to be deemed involuntary; coercion can include threats or implied consequences that pressure a suspect to surrender the right to remain silent.
- Police may not obtain a waiver of Fifth Amendment rights by coupling cooperation (an admission of guilt) with an implied benefit (“make things look good”) or by threatening adverse consequences for refusing to confess (recording the suspect as uncooperative in a way suggesting worse treatment).
- When the record shows a direct causal connection between an impermissible threat and a confession—especially where the confession follows immediately—the confession must be suppressed.
- In assessing the totality of circumstances, courts may consider the suspect’s age, experience, and condition, the custodial setting, and the content and manner of interrogation tactics.
- When a custodial confession is admitted at trial, a defendant may be entitled to a cautionary instruction that accurately states the law and guides jurors in weighing the confession; refusal to give an accurate, requested instruction can be reversible error when the confession is central to the State’s case.

## Conclusion

Because the detective’s ultimatum—portraying Tuttle as cooperative only if he admitted guilt and as “not cooperating” and “a real jerk” if he did not—amounted to an improper threat that immediately triggered the confession, the South Dakota Supreme Court ruled the confession involuntary, reversed the aggravated-assault conviction, and remanded for a new trial with appropriate instructions on evaluating custodial confessions.
