INTERROGATING Offenders with Serious Mental Illness: THE PREVALENCE AND REASONS BEHIND FALSE CONFESSIONS Allison D. Redlich iIIIRG Conference, Stavern, Norway June 24, 2010
Police Interrogation Research • Large increase in research conducted on false confessions • Situational risk factors: certain techniques, length of interrogation • Dispositional risk factors: young age and mental impairment • Over-representation in the criminal justice system • Over-representation among identified false confessors
False Confession Research • Two problematic issues 1. Knowledge is based on, or generated from, specialized subset of egregious cases [coerced-compliant]
Confession Continuum Voluntary Coerced
Confession Continuum Voluntary Coerced
False Confessions Objectively Proven FCs Subjectively Reported FCs • Majority are Voluntary (protecting true perpetrator) • Property crimes, not violent or sexual offenses • 33% retracted and asserted their innocence • Appear to be more common • Almost all Coerced (police induced) • 92% Murder and Rape • Innocent Insisters • Appear to be rare

Self-reported false confessions and false guilty pleas among offenders with mental illness. Law and Human Behavior, 34, 79-90.
Total Sample, n = 1249 • Brooklyn, NY: n = 96 • Washoe County, NV: n = 104 • San Francisco County, CA: n = 264 • Santa Clara County, CA: n = 336 • Hennepin County, MN: n = 244 • Marion County, IN: n = 205
Sample Summary • 61% men • Mean Age = 36.5 years • 12th grade education • Most (86% or more) have a serious mental illness • Average Number of Arrests is 16 • Average number of years offending is 16 years • Almost half have been arrested for a violent/ serious crime

Number of False Confessions • Zero times, n = 969 people, 78% of entire sample • One time = 46% • 2 or 3 times = 34% • 4 to 10 times = 14% • 11 or more times = 6% N = 274 (22%)
NATURE VS. NURTURE DISPOSITIONAL VS. SITUATIONAL
Number of Possible Events • How many times have you falsely confessed? • How many times have you been arrested in your life? • # of FCs/# of arrests
Self-Reported FC Events NY: 33/836 = 3.9% NV: 17/1007= 1.7% CA 1 [SF]: 163/5613 = 2.9% CA 2 [SC]: 331/4387= 7.5% MN: 264/4942 = 5.3% IN: 33/2466 = 1.3% Total 844/19,251 = 4.4%
