The Confession After Six Hours
Detective Nguyen is interviewing a 19-year-old suspect, Devon, about a residential burglary. Devon has an IQ of 71 and reads at a fourth-grade level. He was picked up at 0900 and interviewed after a two-hour wait. Nguyen reads the Miranda waiver, and Devon signs it. Over the next four hours, Nguyen uses a sympathetic approach ("I know you didn't mean for it to go this far"), tells Devon that "things will go easier" if he cooperates, and at hour five says, "Look, we already have your prints on the window-this is just your chance to tell your side." Devon confesses at hour six. In fact, no prints were recovered. Devon has no prior felony history and has never been through the system.

The confession is at serious risk of suppression. Voluntariness turns on the totality of the circumstances, including the suspect's age, education, intelligence, experience with the system, the length of the interrogation, and the tactics used.
Weight against admissibility:
- IQ of 71 and a fourth-grade reading level are significant vulnerabilities; a signed waiver does not end the inquiry if the suspect could not meaningfully understand it.
- Four-plus hours of interrogation after a two-hour wait is lengthy, especially for a 19-year-old with no system experience.
- The sympathetic approach is generally permissible, but the "things will go easier" statement can function as an implied promise of leniency, which renders a confession involuntary if it induced the statement.
- The false-evidence ploy ("we have your prints") is the biggest problem. Fabricating evidence is not per se unconstitutional, but courts weigh it heavily; combined with the other factors it pushes toward coercion.
Weight for admissibility: no physical abuse, no deprivation of food/water/sleep noted, a signed waiver, and no explicit threat of harm.
Likely outcome: a court would find the confession involuntary or at least tainted. The safe practice is to avoid false evidence claims and implied leniency, especially with a vulnerable suspect.
2. What would you have done differently to protect the statement?
Read the worked answer
- Assess vulnerability first. An IQ of 71 and fourth-grade reading level warrant a simplified waiver read aloud, a check for understanding (ask him to explain the rights back), and consideration of whether a guardian or attorney should be involved.
- Record the entire interview from the waiver forward-this both protects the suspect and proves voluntariness.
- Avoid implied promises. "Things will go easier" is the kind of statement that gets a confession thrown out. Say instead: "I can't promise you anything, but I can tell you that being truthful matters."
- Do not fabricate evidence. Use only evidence actually developed. If you want to confront inconsistencies, do it with real facts.
- Keep the interview within a reasonable duration and document breaks, food, water, and restroom access.
- Consider corroboration. Even if the confession is challenged, independent evidence (recovered property, witness statements, video) can support the case without relying on the statement.
