USA: More Innocent People on Death Row Than Estimated: Study

San Quentin's Death Chamber
New research finds that almost four percent of U.S. capital punishment sentences are wrongful convictions, almost double the number of people set free, meaning around 120 of the roughly 3,000 inmates on death row in America are not guilty.

The United States may be putting more innocent people to death than previously thought. According to a sweeping new statistical analysis made public today, the rate of wrongful death sentences in the U.S. is probably much higher than experts have estimated.

Authors of the study say that their “conservative estimate of the proportion of erroneous convictions” is 4.1 percent, or approximately twice the number actually exonerated and set free from death row. This could mean that approximately 120 of the roughly 3,000 inmates on death row in America might not be guilty, while additional scores of wrongfully convicted inmates are serving life in prison after their death sentences were reduced over technical legal errors.

“False convictions … are extremely difficult to detect after the fact,” law professors Samuel R. Gross of the University of Michigan and Barbara O’Brien of Michigan State write in the Proceedings of the National Academy of Sciences, a prestigious peer-reviewed journal. “As a result, the great majority of innocent defendants remain undetected. The rate of such errors is often described as a ‘dark figure’.”

Judge allows Tennessee death row inmates to include botched executions in lawsuit

NASHVILLE, Tenn. (WKRN) — Two failed executions in Tennessee are now at the center of a growing legal battle over the state’s lethal injection protocol after a judge ruled in favor of death row inmates Friday. A Davidson County judge ruled death row inmates can expand their lawsuit to include new allegations stemming from the botched executions of Tony Carruthers and Christa Pike. The original lawsuit, filed in March 2025, argues Tennessee’s death penalty protocol violates the constitutional rights of death row inmates with complex medical conditions. More than one year later, the state then failed to execute two inmates: Tony Carruthers and Christa Pike.

Two men set to be executed in Texas and Oklahoma today

The U.S. was preparing to carry out two executions on Thursday, one in Oklahoma and one in Texas. In Texas, the condemned man is John Allen Rubio, 46, who is set to be put to death at the state prison in Huntsville. He was convicted of beheading three young children he was raising in a 2003 killing that rattled a community along the U.S.-Mexico border. The other man facing execution is James Pavatt, 73, who is set to die by lethal injection at Oklahoma's state penitentiary in McAlester.

Why Many Americans Think Christa Pike Should Undergo a Second Execution Attempt

On October 20, Reuters released the results of a survey showing that 33% of the American public want Tennessee to try again to put Christa Pike to death. Another 26% are undecided. That means 59% of the public would support or be open to such a possibility. I want to suggest a reason why. Second execution attempts are rare in this country and, as a result, the public knows little if anything about them. That may help explain why so many would give Tennessee another chance to kill Christa Pike.
