( Read more... )I've been a police officer for 25 years, and I never understood why someone would admit to a crime he or she didn't commit. Until I secured a false confession in a murder case.
( Read more... )At first, the suspect couldn't tell us anything about the murder, and she professed her innocence. As the interrogation progressed, she became more cooperative, and her confession included many details of the crime. The suspect said she had beaten the man to death and dumped his body by a river. She said she made purchases with the victim's credit card and tried to withdraw cash using his ATM card. Surveillance video from the ATM showed a woman who resembled the suspect, and an expert said the signature on the credit card receipts was consistent with the suspect's handwriting.

We subpoenaed sign-in/sign-out logs from the homeless shelter where she lived, and the records proved that she could not have committed the crime. The case was dismissed, but all of us still believed she was involved in the murder. After all, she had confessed.
Even though it wasn't our standard operating procedure in the mid-1990s, when the crime occurred, we had videotaped the interrogation in its entirety. Reviewing the tapes years later, I saw that we had fallen into a classic trap. We ignored evidence that our suspect might not have been guilty, and during the interrogation we inadvertently fed her details of the crime that she repeated back to us in her confession.
( Read more... )I've learned that this is a nationwide problem. Of the 220 wrongful convictions in the U.S. that have been overturned based on DNA evidence, nearly 25% involved a false confession or false incriminating statements, according to the Innocence Project. In each of those cases, DNA proved that the confession was false.
Threats and coercion sometimes lead innocent people to confess, but even the calmest, most standardized interrogations can lead to a false confession or admission. Those who are mentally ill or mentally disabled may be particularly vulnerable, but anyone can be dazed when confronted by police officers who claim to hold unshakable evidence of one's guilt. Some confess to crimes because they want to please authority figures or to protect another person. Some actually come to believe they are guilty, or confess to do penance for some unrelated bad behavior. Innocent people come to believe that they will receive a harsher sentence -- even the death penalty -- if they don't confess.
