New technologies leading to criminal retrials in Japan

DNA testing has resulted in acquittals of some death-row inmates.

“In the world of engineering, when an airplane accident occurs, a thorough investigation is conducted. But what on earth are the people involved in laws doing when serious human error is committed in the cases of wrongful convictions?”

OSAKA — With the recent release of a couple from prison after a court ordered a 1995 arson-murder case reopened and other such retrials in Japan, more people previously convicted of serious crimes are getting a second shot at proving their innocence.

Technical innovations in DNA forensic science modeled on activities in the United States, as well as the introduction of a lay judge system, are creating a framework that could provide lawyers and “criminals” with access to various experts to help prove the innocence of persons suspected to have been wrongfully convicted.

But the road to change has many hurdles.

Recently, Keiko Aoki and Tatsuhiko Boku, who had been serving a life sentence for lighting a fire that killed the woman’s 11-year-old daughter, were freed after 20 years behind bars.

The Osaka High Court concluded that a retrial was appropriate as the fire could have been accidental, drawing on an experiment conducted by the couple’s lawyers to simulate the fire. Moreover, doubt was cast on the confession from Boku, the women’s de facto husband, as the simulation demonstrated the fire having caught in a different way.

In 1990, Toshikazu Sugaya was arrested and convicted with a life sentence by a high court in Tochigi Prefecture for the murder of a 4-year-old girl. It was determined that DNA evidence from body fluids on the dead girl’s clothing matched Sugaya’s.

But with the primitive forensic technology at the time of the man’s arrest, a little more than eight out of every 1,000 people would have also drawn an identical DNA match. Upon a further test in 2009, DNA evidence conclusively showed Sugaya’s innocence, and he was acquitted and awarded about 80 million yen in state compensation.

Perhaps even more sensational due to the international attention it gained was the case of Govinda Prasad Mainali, a Nepalese man who was wrongly jailed for 15 years while serving a life sentence in the 1997 murder of a Japanese female Tokyo Electric Power Co. worker who reportedly had moonlighted as a prostitute.

The Tokyo High Court ordered a retrial after sets of exculpatory DNA evidence were linked to an unidentified man who had sexual contact with the victim just hours before her death. Mainali was released and deported back to his native country, pending a retrial.

Swabs of semen recovered from the women’s body that the prosecution deemed too small a sample to analyze using the existing technologies at the time, underwent DNA testing in 2011 and were determined not to be from Mainali.

Mainali was formally acquitted in November 2012 and later awarded 68 million yen in compensation for his wrongful imprisonment.

Iwao Hakamada was exonerated by a DNA test after 48 years on death row.
Former professional boxer Iwao Hakamada, who had been sentenced to the death penalty in a 1966 quadruple homicide case, was released after nearly 48 years behind bars when a DNA test showed that blood stains detected on the culprit’s clothing did not belong to Hakamada.

The blood was thought to be that of the attacker and was previously determined unlikely to be from any of the victims.

In Japan, prosecutors have a staggering 99 percent conviction rate. Confessions are in most cases considered the king of evidence and acquittals are anathema to ambitious prosecutors and judges alike, experts argue.

Although it appears retrials in Japan could be on the rise, many point out that without “convincing and fresh” evidence the courts remain reluctant to order retrials. And even with fresh evidence, unless it can conclusively prove the person’s innocence, requests for retrials have historically been denied.

Inspired by the U.S.-based Innocence Project, researchers in Japan aim to launch a support network next spring for people believed to have been wrongly convicted.

Mitsuyuki Inaba, a professor at the College of Policy Science and Graduate School of Policy Science at Ritsumeikan University, is spearheading the project. He bemoans the lack of remorse expressed by investigators in wrongful conviction cases and says that more must be done to determine their cause.

“In the world of engineering, when an airplane accident occurs, a thorough investigation is conducted. But what on earth are the people involved in laws doing when serious human error is committed in the cases of wrongful convictions?” Inaba said.

The Innocence Project, which was founded in 1992 at the Benjamin N. Cardozo School of Law at Yeshiva University in New York City, serves as a nonprofit organization.

In questionable cases, scholars, journalists and lawyers work together to gather new evidence in response to prisoners who claim innocence. New technologies such as DNA testing and research of cases from fresh perspectives have resulted in retrials and acquittals of some death-row inmates.

Similar activities are spreading in countries like France, Australia and Taiwan, leading to a global network.

Kana Sasakura, an associate professor of the Konan University Faculty of Law in Kobe, said that Japanese courts will not allow a retrial unless new evidence is strong enough to overturn the original judgment. Moreover, collecting such evidence is extremely difficult.

“Unlike in ordinary criminal trials, there is no system for court-appointed defense lawyers, who are publicly financed, at retrials,” said Sasakura. “It is very difficult for convicts held in prisons and detention houses to collect new evidence by themselves that could overturn their conviction.”

“In the future, it would be desirable for the Japanese project to be operated like an NPO, raising donations from the public. For the time being, however, it will probably be operated more stably by having the head office at a university, which will be useful for education if students are interested in joining,” Sasakura said.

Florida executes Chadwick Scott Willacy

STARKE, Fla. -- A Florida man who set his neighbor on fire after she returned from work to find him burglarizing her home was executed Tuesday evening. Chadwick Scott Willacy, 58, received a three-drug injection and was pronounced dead at 6:15 p.m. at Florida State Prison near Starke for the 1990 killing of Marlys Sather. It was Florida's fifth execution this year. The curtain to the execution chamber went up promptly at the scheduled 6 p.m. time, and the lethal injection got underway two minutes later, after Willacy made a brief statement.

Florida | Man avoids death penalty in Daytona Beach triple murder

Jerome Anderson shot and killed Antoine Melvin, 42, John Burch, 65, and Patrick Lassiter, 35, in 2023. A man pleaded no contest to a triple-murder in Daytona Beach and was sentenced April 20 to three consecutive life terms in prison as part of a plea deal in which he avoided a possible death sentence. Jerome Anderson, 41, was indicted on three counts of first-degree murder and possession of a firearm by a convicted felon in the 2023 triple-slaying. Anderson pleaded no contest to the three first-degree murder charges April 20 and, in exchange, Assistant State Attorney Andrew Urbanak agreed not to continue to pursue the death penalty.

Florida Schedules Two Executions for Late April

TALLAHASSEE, Fla. — Governor Ron DeSantis has directed the Florida Department of Corrections to move forward with two executions scheduled for late April 2026, marking a significant ramp-up in the state's use of capital punishment. The scheduled deaths of Chadwick Willacy and James Ernest Hitchcock follow a series of landmark judicial rulings that have kept both men on death row for decades.

20 Minutes to Death: Witness to the Last Execution in France

The following document is a firsthand account of the final moments of Hamida Djandoubi, a convicted murderer executed by guillotine at Marseille’s Baumettes Prison on September 10, 1977. The record—dated September 9—was written by Monique Mabelly, a judge appointed by the state to witness the proceedings. Djandoubi’s execution would ultimately be the last carried out in France before capital punishment was abolished in 1981. At the time, President Valéry Giscard d'Estaing—who had publicly voiced his "deep aversion to the death penalty" prior to his election—rejected Djandoubi’s appeal for clemency. Choosing to let "justice take its course," the President allowed the execution to proceed, just as he had in two previous cases during his term:   Christian Ranucci , executed on July 28, 1976 and Jérôme Carrein , executed on June 23, 1977. Hamida Djandoubi , a Tunisian national, was sentenced to death for killing his former lover, Elisabeth Bousquet. He was execu...

Iran to execute first woman linked to mass protests after ‘forced confessions’

Bita Hemmati and three others have been sentenced to death for 'collusion' and 'propaganda.' Advocates claim the charges are baseless, citing a secretive process and state-televised interrogations. Iranian authorities are preparing to execute Bita Hemmati, the first woman sentenced to death in connection with the mass protests in Tehran in late December and January, according to the US-based non-profit the Human Rights Activists News Agency. Judge Iman Afshari, of Branch 26 of the Tehran Revolutionary Court, sentenced Hemmati, her husband, Mohammadreza Majidi Asl, and Behrouz Zamaninezhad, and Kourosh Zamaninezhad to death on the charge of “operational action for the hostile government of the United States and hostile groups,” in addition to discretionary imprisonment period of five years on the charge of “assembly and collusion against national security.”  

Arizona | Man who murdered pastor crucifixion style requests plea deal after parents killed in plane crash

Adam Sheafe, the California man who admitted to killing a New River, Arizona, pastor in a crucifixion-style attack, has asked prosecutors to offer him a plea deal that would result in a natural life sentence rather than the death penalty he had previously sought. Advisory council attorneys representing Sheafe sent a formal plea offer to prosecutors this week, about two weeks after his father and stepmother died in a plane crash at Marana Airport on April 8, according to 12 News. Sheafe, 51, is charged with first-degree murder in the death of William Schonemann, 76, pastor of New River Bible Church, who was found dead inside his home last April.

Singapore executes man for trafficking 1kg of cannabis

SINGAPORE — Singaporean authorities executed Omar bin Yacob Bamadhaj at Changi Prison on Thursday, April 16, 2026, following his 2019 conviction for importing 1,009.1 grams of cannabis. Bamadhaj, 41, though some reports have cited his age as 46, was arrested on July 12, 2018, during a routine search at the Woodlands Checkpoint. Officers discovered the narcotics wrapped in plastic and hidden within his vehicle as he attempted to enter Singapore from Malaysia.  Under the Misuse of Drugs Act, the threshold for the mandatory death penalty involving cannabis is 500 grams, a limit this shipment exceeded by more than double.

Tennessee | Man set to be executed files motion claiming DNA evidence will exonerate him

MEMPHIS, Tenn. — Attorneys for death row inmate Tony Carruthers filed a motion in Shelby County Criminal Court seeking immediate DNA testing on evidence they claim will prove his innocence in a 1994 triple murder.  Carruthers is scheduled for execution on May 12. He was convicted and sentenced to death for the kidnapping and murders of 24-year-old Marcellos Anderson, 17-year-old Delois Anderson, and 21-year-old Frederick Scarborough. Prosecutors at trial alleged the victims were buried alive in a Memphis cemetery as part of a drug-related robbery.

US Department of Justice announces decision to resume federal executions

The Department of Justice (DOJ) announced on Friday that it will resume the federal use of capital punishment and that it is seeking death sentences against 44 defendants. DOJ also said that it will use firing squads, electrocution, or nitrogen asphyxiation if the drug used in lethal injection is unavailable. The announcement follows the Restoring and Strengthening the Federal Death Penalty report, published on April 24. The report is especially critical of the moratorium on federal executions, ordered by Attorney General Merrick Garland in July 2021, to remain until the death penalty could be conducted “fairly and humanely.” Garland was concerned about the federal lethal injection protocol, which uses only one drug, pentobarbital, and the possibility that it causes “unnecessary pain and suffering.” In response to Garland’s moratorium and concerns, President Biden commuted the sentences of 37 prisoners on federal death row, leaving only three prisoners.

Florida Supreme Court upholds death sentence for man who raped & killed girl, babysitter in 1990

FORT MYERS, Fla. — The Florida Supreme Court on Friday affirmed the convictions and death sentences of Joseph Zieler for the 1990 murders of an 11-year-old girl and her babysitter, clearing the way for his execution after decades of the case remaining unsolved. Zieler, 61, was sentenced to death in 2023 for the slayings of Robin Cornell and Lisa Story. The decision by the state’s highest court marks a pivotal moment in one of Southwest Florida’s most notorious cold cases, which saw no progress until a 2016 DNA match linked Zieler to the crime scene.
