Report Finds 375 Ohio Wrongful Convictions Since 1989, Questions Death Penalty
New research reveals 375 people have been wrongfully convicted in Ohio since 1989, with one in every 8.7 death row inmates later exonerated.

COLUMBUS, OHIO β A comprehensive new report released this week documented 375 wrongful convictions in Ohio since 1989, with researchers concluding the state’s death penalty system remains “profoundly unreliable” due to persistent flaws in the justice system.
The Ohio Innocence Project and University of Cincinnati College of Law compiled the data showing that wrongful convictions have occurred across all 88 Ohio counties, affecting cases ranging from minor offenses to capital murder charges. The report found that 11 people on Ohio’s death row have been exonerated since the state resumed executions in 1999.
“These numbers represent real people whose lives were derailed by a system that is supposed to protect them,” said Mark Godsey, director of the Ohio Innocence Project. “Each wrongful conviction is a failure of the system and a reminder that we must do better.”
Leading Causes of Wrongful Convictions
According to the report, the primary factors contributing to wrongful convictions in Ohio include perjury or false accusations, official misconduct, mistaken eyewitness identification, and inadequate legal defense. The research revealed that 42% of exonerations involved cases where defendants had been convicted of violent crimes.
The study found that Black defendants were disproportionately represented among the wrongfully convicted, comprising 52% of exonerees despite making up 13% of Ohio’s population. Men accounted for 89% of those wrongfully convicted, according to the data.
Cuyahoga County led the state with 95 documented wrongful convictions, followed by Hamilton County with 37 cases. Franklin County, which includes Columbus, recorded 23 wrongful convictions during the study period.
Death Penalty System Under Scrutiny
The report specifically criticized Ohio’s capital punishment system, noting that one in every 8.7 people sentenced to death row since 1981 has been exonerated. Researchers argued this error rate demonstrates fundamental problems with the state’s ability to accurately determine guilt in the most serious cases.
“The death penalty is the ultimate punishment, but our research shows it’s being applied by a system with a documented history of convicting innocent people,” the report stated. Ohio has executed 56 people since resuming capital punishment, while 11 death row inmates have been exonerated.
The study highlighted several high-profile cases, including that of Derrick Wheatt, who spent 18 years in prison for a murder he did not commit before DNA evidence led to his exoneration in 2019.
Calls for Criminal Justice Reform
Researchers recommended several reforms to reduce wrongful convictions, including improved eyewitness identification procedures, better funding for public defenders, mandatory recording of police interrogations, and expanded access to post-conviction DNA testing.
The report also called for increased transparency in prosecutorial offices and enhanced training for law enforcement officers on evidence collection and interview techniques.
“Every wrongful conviction erodes public trust in our justice system and inflicts immeasurable harm on innocent individuals and their families,” said Jennifer Bergeron, a University of Cincinnati law professor who contributed to the research. “These reforms are not just suggestions β they’re necessities for a fair and accurate system.”
Ohio currently has 135 people on death row, according to the Department of Rehabilitation and Correction. The state has not carried out an execution since July 2018, when Robert Van Hook was put to death for a 1985 murder in Hamilton County.
The complete report, titled “The Ohio Innocence Project Registry,” is available online and includes detailed case information for each documented wrongful conviction. Researchers plan to update the database annually as new exonerations occur.
