The case of 71-year-old Douglas Stewart Carter, who was released in Utah after 41 years in prison and awaiting the death penalty, is just one of many examples that show the serious consequences of wrongful convictions in the United States.
Carter was convicted in 1985 of the murder of Eva Olesen and was re-convicted in a second trial in 1992. His conviction was based largely on the testimonies of two people and a confession, which Carter claimed for decades to have been obtained under pressure from the police.
Years later, both witnesses admitted that they had been paid and pressured by police to testify against Carter. Meanwhile, new DNA tests conducted on samples preserved from the crime scene showed no match to his genetic material.
The Utah Supreme Court had already ordered a new trial, citing “serious errors” in the investigation of the case. After more than four decades behind bars, Carter was released.
His case is not isolated. Data from the Innocence Project, an American organization known for using DNA to review the cases of wrongfully convicted people, shows the scale of the problem.
By April 2026, the organization had recorded 257 court victories for the people it represented, and in 205 of these cases DNA played a decisive role in overturning the conviction.
In total, these people have spent around 4,102 years in prison, despite their convictions later being overturned or acquitted of the charges.
Behind this figure lie stories of people who lost years, even decades, of their lives due to errors in investigations, inaccurate testimony, mistaken identifications, confessions obtained under pressure, or forensic evidence that later proved to be inaccurate.
Kirk Bloodsworth, the death row inmate who was saved by DNA
One of the most famous cases is that of Kirk Bloodsworth. He was convicted in 1985 of the rape and murder of a nine-year-old girl in Maryland and sentenced to death.
Bloodsworth insisted from the beginning that he was innocent. His conviction was based largely on witness statements. Years later, when DNA testing began to be used in criminal cases, biological samples preserved from the crime scene were analyzed.
The results showed that Bloodsworth was not the perpetrator. In 1993, he became the first death row inmate in the US to be exonerated thanks to DNA testing.
The case took another turn when the same genetic material was linked to another person, who turned out to be the real perpetrator of the crime.
Ronald Cotton, the identification that landed the wrong person in prison
Another well-known case is that of Ronald Cotton in North Carolina.
In 1984, Jennifer Thompson was sexually assaulted and during the investigation identified Cotton as the perpetrator. Her identification was one of the key pieces of evidence in the case against him.
Cotton denied the charges but remained in prison for more than a decade. In 1995, DNA tests showed that biological material found in the case did not belong to him.
Analysis linked the material to Bobby Poole, another man with a history of sexual assault. Cotton was acquitted of the charges.
The case became one of the best-known examples of the danger posed by mistaken eyewitness identification, especially when the identification is carried out after a traumatic event or through problematic procedures.
The Five Young Men of Central Park
Another case that shocked American public opinion was that of the five teenagers later known as the "Central Park Five".
In 1989, after the brutal attack on a woman jogging in New York City's Central Park, five teenagers aged 14 to 16 were arrested and questioned for hours.
The young men gave confessions, but their statements contained contradictions and did not match each other on several key points. DNA found at the crime scene also did not link them to the attack.
Despite this, all five were convicted.
In 2002, Matias Reyes, a man convicted of other violent crimes, confessed to the attack. DNA tests confirmed his confession, and the convictions of the five young men were overturned.
The case became one of the most well-known examples in the US of the dangers of false confessions, especially when the suspects are minors and face long, stressful interrogations.
42 years behind bars
Another remarkable story is that of Ervin Harris in Alabama.
Harris was only 20 years old when he was convicted of a rape committed in 1974. One of the key elements of the case was his identification by witnesses.
He was sentenced to 99 years in prison and spent 42 years behind bars. He was released on parole in 2017, but his conviction was overturned in June 2026 after a reassessment of the case and evidence related to the reliability of the identifications.
Harris was 20 years old when he entered prison and 62 when he was released. Within these two ages lie more than four decades of his life.
Testimonies and confessions, among the main factors
According to data from the Innocence Project, mistaken identification by eyewitnesses is present in a large proportion of the organization's cases. In 62% of cases, mistaken identification by witnesses was evidenced.
In about 52% of cases, incorrect or problematic use of forensic science was identified, while 29% involved false confessions or admissions of guilt.
In about 19% of cases, unreliable informants or witnesses were also identified.
These cases have caused the debate in the US to focus not only on the release of wrongfully convicted persons, but also on the way investigations are conducted, identifications are made, suspects are questioned, and scientific evidence is used.
The mistake that could convict two people
The consequences of a wrongful conviction are not limited to the person who ends up in prison.
According to the Innocence Project, 89 real perpetrators have been identified in the cases it has handled, who have later been linked to 101 other violent crimes, including 56 sexual assaults, 22 murders, and 23 other violent offenses.
This means that when an innocent person is convicted, in some cases the real perpetrator can remain free and commit other crimes.
The years that never come back
The Innocence Project's data also shows the large difference between the age of people when they are convicted and the age when they are released.
The people in the organization's cases were on average about 27 years old when they were convicted, while the average age when they were released was about 45 years old.
The case of Douglas Carter illustrates this cost even more clearly. He entered the justice system as a young man and emerged from it at the age of 71, having spent 41 years behind bars.
Such cases have fueled discussion about how justice should handle evidence, testimony, and confessions, especially when new technologies may offer opportunities to revisit old cases.
A conviction can be overturned and a person can be released from prison, but lost decades can never be brought back.
