False Confessions - Contamination

Contamination is the root cause of false confessions. Confessions/admissions should be independently verifiable by eliciting information from the offender that only the offender would know. Questions contaminate responses. The questioner's response to answers contaminates responses. So, questions have to be carefully constructed and all possible sources of contamination need to be minimized. Careful selection of the interview room; the number of people in the interview; making sure only one person conducts all interviews; careful construction of questions; using only mutually understood words in the questions are a few examples.

False Confessions

Recent studies of over 125 DNA evidence cases leading to exoneration:

25% of overturned wrongful convictions involved false confessions.

33% of those false confessions were juveniles, a disproportionate percentage.

84% of false confessions occurred after 6 hours of interrogation.

Another Great Endorsement

“Joe Koenig’s meticulous assessment of the case against or for Walt Reca as D.B. Cooper is objective, deep and highly persuasive. It should be a model for writers of critical analyses of other cases yet to be offered of other mysteries. Precious few of the tens of thousands of police reports I have reviewed as federal and state prosecutor match this work.”

 

John Smietanka, Former US Attorney and Principal Associate Deputy US Attorney General

“Joe Koenig provides a compelling case that Walt Reca is D.B. Cooper. It’s as if the reader is sitting in a courtroom experiencing a prosecutor building a step by step case, presenting relevant facts.”
