At least 202 people sentenced to death in the United States have been exonerated since 1973, according to the Death Penalty Information Center’s tracking database.1Death Penalty Information Center. Innocence That works out to roughly one exoneration for every eight executions carried out in the modern era. The pace has not slowed: three people were cleared from death row in 2024 alone.2Death Penalty Information Center. The Death Penalty in 2024: Innocence
What the 202 Figure Actually Counts
Not every reversed capital conviction is on that list. The Death Penalty Information Center, which maintains the most widely cited tally, counts someone as exonerated only if one of three things happened:1Death Penalty Information Center. Innocence
- A jury or judge found the defendant not guilty at retrial on all charges that originally placed them on death row.
- An appellate court vacated the conviction and the prosecution dropped the case.
- A governor or other executive official granted a full pardon based on evidence of innocence.
The distinction from a commutation matters. A commutation changes a death sentence to life in prison but leaves the conviction in place. An exoneration wipes the conviction and recognizes the person’s innocence. Someone whose sentence was commuted is still legally a convicted murderer; someone exonerated is not.
How Long Exonerees Waited to Be Cleared
Half of all death row exonerations have taken more than a decade, and the wait keeps growing.3Death Penalty Information Center. Time on Death Row More than half of the exonerations since 2013 have taken 25 years or more. In 2024, the average time between conviction and exoneration reached an all-time high of 38.7 years.4Death Penalty Information Center. New Analysis: Innocent Death-Sentenced Prisoners Wait Longer Than Ever for Exoneration
Larry Roberts, the 200th person exonerated from death row, had been imprisoned for 41 years. Kerry Max Cook, cleared by the Texas Court of Criminal Appeals in June 2024, spent nearly 20 years on death row and decades more fighting through the courts. Daniel Gwynn spent nearly 30 years on Pennsylvania’s death row before a reinvestigation found his confession had been coerced and the eyewitness identification was faulty.2Death Penalty Information Center.

The wait is not evenly distributed. Black death row exonerees wait more than four years longer than white exonerees to be cleared.5Death Penalty Information Center. Article of Interest: ACLU Releases New Report Citing Pervasive Racial Imbalance in Capital Punishment System Official misconduct has been documented at higher rates in capital cases involving Black and Latino defendants, which makes wrongful convictions in those cases both more likely and harder to uncover later.
Where Death Row Exonerations Happen Most
Three states account for a substantial share of the total. Florida leads with 30 death row exonerations, followed by Illinois with 22 and Texas with 18.6Death Penalty Information Center. The 200th Exoneration Underscores Critical Flaws in the U.S. Criminal Legal System The ranking tracks how heavily each state has used the death penalty. Illinois eventually abolished capital punishment, in part because its exoneration rate revealed deep problems in how capital cases were prosecuted. Florida and Texas continue active use, and both have seen exonerations emerge decades after the original convictions.
A high count in one state can mean two very different things. It can reflect a system that produced a lot of errors, or a system that has become better at catching them. Some jurisdictions now have conviction integrity units that proactively review old cases. Others lack meaningful post-conviction review, which means wrongful convictions in those places are less likely to be discovered, not less likely to exist.
Why These Convictions Were Wrong
The causes overlap and compound each other, but several patterns show up repeatedly in the case files behind the 202.
False Testimony
Perjury or false accusation appears in close to 70 percent of death row exonerations. Witnesses lie under pressure from investigators, in exchange for reduced charges on their own cases, or because they are mistaken and will not back down. Confident testimony from someone claiming to have seen the defendant at the scene is extraordinarily hard for a jury to discount, even when the physical evidence is thin.
Official Misconduct
Police and prosecutors have withheld favorable evidence from the defense in a disturbing share of capital cases, in violation of the disclosure duty the Supreme Court established in Brady v. Maryland.7Justia US Supreme Court. Brady v. Maryland, 373 U.S. 83 (1963) Violations often go undetected for years, until a post-conviction review team uncovers buried lab reports, undisclosed witness statements, or deals made with jailhouse informants.
Flawed Forensic Evidence
Flawed forensic analysis plays a role in roughly one out of every three wrongful capital convictions. That includes discredited techniques like bite-mark comparison, hair microscopy matching, and outdated arson investigation methods. As scientific standards evolve, techniques once treated as reliable get debunked, but the convictions resting on them do not automatically get revisited.
Eyewitness Misidentification
Memory is far less reliable than most people assume, and the way lineups are conducted can steer a witness toward a particular suspect. Cross-racial identifications are especially error-prone. Once a witness picks someone out and testifies with certainty, that identification carries enormous weight with juries.
The Limited Role of DNA
DNA testing gets most of the public credit for exonerations, but it appears in only about 17 percent of death row cases, covering 34 exonerations across 15 states.8Death Penalty Information Center. The Limitations of DNA Evidence in Innocence Cases Most crimes do not leave testable biological evidence. The majority of exonerations come from recanting witnesses, newly discovered documents, or reinvestigation by conviction integrity units. Treating DNA as the primary safeguard against executing innocent people overstates its reach.
The Innocent People Who Were Not Exonerated
The 202 got out. The harder question is how many innocent people did not. The Death Penalty Information Center maintains a separate list of individuals executed since 1976 where later evidence has raised serious doubts about guilt, and notes that there is no way to tell how many of the more than 1,600 people executed may have been innocent.9Death Penalty Information Center. Executed But Possibly Innocent
Cameron Todd Willingham was executed in Texas in 2004 for allegedly setting a fire that killed his three children. His conviction rested on arson investigators’ testimony that the fire was intentionally set. After his execution, five independent arson experts reviewed the evidence and concluded that none of the original forensic analysis was valid.
Marcellus Williams was executed in Missouri in September 2024 for a 1998 killing he maintained he did not commit. DNA recovered from the murder weapon excluded him as a source. The prosecuting attorney filed a 63-page motion to vacate the conviction, citing new DNA evidence, doubts about witness credibility, and racially discriminatory jury selection. The DNA on the knife matched the trial prosecutor and his investigator, who had handled the weapon without gloves. The execution went forward after state courts denied the motion and the U.S. Supreme Court declined to intervene.
A 2014 study published in the Proceedings of the National Academy of Sciences estimated that at least 4.1 percent of people sentenced to death would eventually be exonerated if they remained under sentence indefinitely, which suggests the true innocence rate is meaningfully higher than the discovered exoneration rate of 202.
What Happens After Release
An exoneration ends the sentence but not the fallout. Federal law allows people wrongfully convicted of federal crimes to seek compensation of up to $100,000 for each year spent on death row.10Office of the Law Revision Counsel. United States Code Title 28 – Section 2513 Thirty-eight states and the District of Columbia have their own wrongful conviction compensation statutes, though amounts vary widely, and the remaining states offer no statutory compensation at all. Many exonerees also pursue civil rights claims under 42 U.S.C. ยง 1983 against officials who violated their constitutional rights, though qualified immunity and short filing windows make those cases difficult.11Office of the Law Revision Counsel. United States Code Title 42 – Section 1983
Unlike parolees, exonerees typically are not eligible for government reentry services such as transitional housing or job placement. Someone released after decades on death row may lack a valid ID, employment history, or access to healthcare. Expungement is not automatic, and nearly a third of exonerees have reported that their records were never fully cleared.
