Whether prompted by stress, sleep deprivation, police coercion or a desire for attention, people frequently confess to crimes they didn’t commit. Advancements in DNA testing, time and again, have led to exonerations of innocent people who gave false confessions, sometimes after they spent years or decades behind bars.
False confessions can “ruin people’s lives and their family’s lives,” Richard Leo, a law and psychology professor at the University of San Francisco School of Law and the author of Police Interrogation and American Justice, tells A&E Crime + Investigation. “It may or may not be a low-probability event, but it is a high-consequence event—some people think it’s the worst event you could have in our criminal justice system.”
How Common Are False Confessions?
In 2024, 22 out of 147 exonerations in the United States—or 15%—involved false confessions, according to the National Registry of Exonerations, a project that has tracked more than 3,700 known U.S. exonerations since 1989. While “hundreds and hundreds” of false confessions have been documented, Leo says coming up with precise historical numbers proves difficult. “There’s no database maintained by the government, by which we could randomly sample interrogations, figure out what percentage lead to confessions and then figure out what percentage of those confessions are true or false,” Leo says.
Saul Kassin, a psychology professor at the John Jay College of Criminal Justice, tells A&E Crime and Investigation that false confessions are “frighteningly common, more so than people think.”
“It’s tricky to know because confessions look and sound real, and people can’t tell the difference by watching and listening between a true and false confession,” Duped: Why Innocent People Confess—and Why We Believe Their Confessions author Kassin says.
What Are Voluntary False Confessions?
Kassin distinguishes between “voluntary” and “police-induced” false confessions. Voluntary confessions are less common and occur when people claim responsibility for crimes they didn’t commit—without prompting from investigators.
“That happens for a variety of reasons—some rational: maybe people protecting someone else, protecting a loved one or taking the blame for something someone else did,” Kassin says. “And sometimes, these are less rational: people seeking attention.”
That’s particularly true in high-profile cases. More than 200 people voluntarily confessed to the 1932 kidnapping of famed aviator Charles Lindbergh’s infant son. The man who was convicted of the crime did not.
In 2006, former schoolteacher John Mark Karr confessed to murdering 6-year-old JonBenét Ramsey in December 1996 in her Colorado home. As the still unsolved crime generated national headlines, prosecutors dropped their case against Karr after DNA evidence failed to place him at the crime scene.
“When somebody volunteers a confession to police, the reaction is one of skepticism,” Kassin says. “You say you committed this crime? Prove it. Tell me what you know about this crime scene and victim and whatnot.”
