The longest-serving death row inmates in recorded history are Raymond Riles of Texas, who spent more than 45 years under a death sentence before being resentenced to life in 2021, and Iwao Hakamada of Japan, who spent 46 years awaiting execution before a court acquitted him in 2024. Their cases sit at the far end of a trend that has reshaped capital punishment: the average wait between a death sentence and execution in the United States has climbed from about six years in the mid-1980s to over 23 years for inmates executed in 2023.1Bureau of Justice Statistics. Capital Punishment, 2023 – Statistical Tables
Raymond Riles: The US Record
Raymond Riles was sentenced to death on December 11, 1975, for the murder of John Thomas Henry at a Houston car lot. The killing happened during a dispute over a used car purchase in December 1974. Riles shot Henry in the back and then robbed him before fleeing.2Justia Law. Riles v State 1977 What followed was not a swift path to execution but a decades-long standstill driven almost entirely by his mental health.
Courts repeatedly found Riles incompetent to participate in legal proceedings. Under the Eighth Amendment, a person cannot be executed if their mental state is so impaired that they cannot grasp the connection between their crime and the punishment.3Constitution Annotated. Amdt8.4.9.7 Cognitively Disabled and Death Penalty Riles fell squarely into that category. His case cycled through competency evaluations for more than three decades. In April 2021, the Texas Court of Criminal Appeals threw out his death sentence because the original jury had never been instructed to weigh his mental illness. Two months later, a Harris County judge resentenced him to life in prison, ending 45 years on death row.
Gary Alvord: The Previous US Record Holder
Before Riles, the record belonged to Gary Alvord. A Florida court sentenced Alvord to death on April 9, 1974, for murder. He faced execution at least twice, but his severe mental illness kept the state from carrying it out. In 1984, he was transferred to a state hospital for psychiatric treatment. Doctors there refused to treat him, citing the ethical problem of restoring a patient’s competency so he could be killed. Alvord’s final appeal expired in 1998, yet the execution never happened. He died of natural causes on May 19, 2013, at age 66, after nearly 40 years on death row.
Other Decades-Long Stays in the United States
Riles and Alvord are not isolated outliers. Several other inmates have spent more than three decades awaiting execution.
- Douglas Stankewitz was sentenced to death in California in 1978. He spent 43 years on death row before his sentence was reduced to life without parole in 2019.
- Carey Dean Moore spent 38 years on Nebraska’s death row after being sentenced in 1980 for two murders. He was executed in 2018, one of the longest waits that actually ended in execution.
As of 2020, inmates still waiting on death row had been there for an average of 19.4 years.4Bureau of Justice Statistics. Capital Punishment, 2020 – Statistical Tables For the roughly 2,100 people currently under a death sentence in the United States, the wait keeps growing.
Iwao Hakamada: The World Record
The longest confirmed death row stay anywhere in the world belongs to Iwao Hakamada of Japan. In 1968, a court convicted Hakamada of murdering his employer, the man’s wife, and their two teenage children, along with arson. He was sentenced to death and spent the next 46 years in confinement awaiting execution.
His case became an international cause after evidence emerged that key items used to convict him may have been fabricated. In 2014, a Japanese court ordered his release and granted a retrial. Hakamada, by then in his late 70s and suffering severe psychological deterioration after decades in isolation, was freed from prison. On September 26, 2024, the Shizuoka District Court acquitted him, concluding that investigators had planted evidence. He was 88 years old.
Hakamada’s case points to a pattern the American examples also show. The inmates who spend the longest on death row are rarely there because the system is working through routine appeals. They are there because something went fundamentally wrong: a defendant’s mental collapse, fabricated evidence, or a legal system unable to resolve its own contradictions.
Why Death Row Stays Stretch for Decades
Mandatory Appeals
In every state that imposes the death penalty, a death sentence triggers an automatic appeal to the state’s highest court. The reviewing court examines whether the trial was conducted properly, whether the evidence supports the conviction, and whether the sentence was influenced by bias or arbitrary factors. If the court finds an error, it can send the case back for a new trial or a new sentencing hearing, which restarts the clock. Even when the appeal is denied, the process alone typically takes several years. Multiple rounds of state and federal review can stretch that to a decade or more.
Mental Competency
The Supreme Court held in Ford v. Wainwright (1986) that the Eighth Amendment forbids executing a prisoner who is insane.5Justia US Supreme Court. Ford v Wainwright 477 US 399 1986 In Panetti v. Quarterman (2007), the Court clarified that the test is whether the prisoner can reach a rational understanding of why the state is executing them.3Constitution Annotated. Amdt8.4.9.7 Cognitively Disabled and Death Penalty
This is exactly what kept Riles alive for 45 years. When a court finds an inmate incompetent, the case goes into a holding pattern. The inmate undergoes periodic psychiatric evaluations. If competency is never restored, the execution cannot proceed. The sentence stays in place, and so does the inmate.
Post-Conviction DNA Testing
DNA analysis, unavailable during many trials from the 1970s and 1980s, has become a powerful tool for re-examining old convictions. Under federal law, an inmate can file a motion for post-conviction DNA testing by asserting actual innocence, identifying specific evidence in government possession, and showing that favorable results would create a reasonable probability they did not commit the crime.6Office of the Law Revision Counsel. 18 USC Ch. 228A Post-Conviction DNA Testing Most states have their own versions of these statutes.
When testing is granted, forensic analysis and subsequent hearings can add years to an already long timeline. The results matter. At least 185 people have been exonerated from death row in the United States, and DNA evidence played a role in a significant share of those cases.
Statewide Moratoriums and Judicial Stays
Some of the longest death row stays have nothing to do with an individual inmate’s case. Governors in several states have imposed moratoriums that halt executions statewide. California’s is the largest in scale. In 2019, Governor Gavin Newsom signed an executive order granting a reprieve to every person sentenced to death in the state, calling the system “unfair, unjust, wasteful, protracted.”7Governor of California. Executive Order N-09-19 The order did not vacate anyone’s death sentence. It paused the final step, leaving more than 600 inmates on death row with no execution date and no changed sentence. Oregon and Colorado have similar moratoriums.
Judicial stays create similar freezes. When courts take up challenges to execution methods, such as whether a particular lethal injection protocol causes unconstitutional pain, they sometimes halt executions across an entire jurisdiction until the question is resolved. These pauses can last years. During that time, inmates remain in the same high-security housing under the same death sentence, aging without resolution.
What Decades on Death Row Actually Look Like
Death row housing is designed for short-term maximum security, not for people who will live there for 20, 30, or 40 years. Cells typically range from 36 square feet to just over 100 square feet, and most contain a steel bed or concrete slab, a steel toilet, and a small writing table.8Office of Justice Programs. Death Before Dying: Solitary Confinement on Death Row Inmates spend the vast majority of every day inside. Exercise is usually limited to a few hours per week in a small, caged outdoor area.
Social contact is severely restricted. Many death row inmates have no physical contact with other people for years at a time. They are frequently excluded from educational programs, vocational training, and prison jobs. Visitation is generally limited to a few hours per session and often conducted through glass or wire.
Inmates who entered death row in their 20s may be in their 60s or 70s before their case is resolved. Hakamada suffered profound mental deterioration during his 46 years of confinement. Riles was found mentally incompetent for more than 30 years. Whether the isolation caused or worsened these conditions is debated, but the correlation is hard to ignore when the confinement stretches across most of an adult life.

Capital Punishment, 1985 has become 279 months, or just over 23 years, for those executed in 2023.1Bureau of Justice Statistics.
