A prison sentence is a promise about the future, and a release program is the clause in which the state decides how much of the promise to keep. Parole boards vote. Mandatory supervision laws count days. A day-release scheme lets a man out in the morning on his word and expects him back at night, and a halfway house lets him sleep somewhere the state can find him. Each of these is a reasonable device for moving large numbers of prisoners through a system, and each has at some point put a man outside the wall who should have stayed inside it.
The seven cases here are each tied to one such door. Two men left Texas prisons under programs the state had written for the purpose and went on to kill. In a third Texas case, a prosecutor traded away years of freedom in advance for a list of names. One man left a Canadian prison on mandatory supervision, one a French prison on day release, and one a halfway house in St. Louis. The last walked away from a Brazilian furlough and never faced a court. What changed afterward in policy differs from one place to the next, and in some places no change was recorded at all.
Kenneth McDuff was 20 when he killed three teenagers near Fort Worth in August 1966. A jury sentenced him to death. Accounts differ on the scope of the 1966 judgments: the Cleburne Times-Review says he was sentenced to die for the murder of one of the three, KWTX reported in 2024 that he was convicted of all three, and Texas Monthly in 1998 described the conviction as being for one girl’s death. After the Supreme Court’s decision in Furman v. Georgia in 1972, his sentence, along with the 87 other death sentences then in force in Texas, was commuted to life.
He became eligible for parole in 1976, and for 13 years the board turned him down. In 1981 he offered a board member, Glenn Heckmann, $10,000 for his vote; Heckmann reported it, and McDuff was convicted of bribery, though Gary Cartwright of Texas Monthly says the jury misunderstood the habitual-offender instructions and gave him two years, time he had already served. In 1988 the board voted to parole him and then rescinded the decision after letters of protest from the trial judge and the prosecutor.
What changed in 1989 was not McDuff’s case but the Texas prison system. A federal court had ruled in 1972 that Texas prisons were overcrowded, and by 1987, Cartwright wrote, the system was near breakdown. Governor Bill Clements ordered the parole board to release 750 prisoners a week to stay within court-imposed population limits, and when too few prisoners met the standards, the standards were lowered. More than 36,000 people were paroled in 1989 from a system built for about 60,000. Old cases went to "special review" groups that gave them little scrutiny, and twenty former death row prisoners were released, McDuff among them. One lawyer told the magazine the board’s decisions were "as random as throwing darts." The 1989 Criminal Justice Reform Act had placed the board under the Texas Department of Criminal Justice, which gave the prison division leverage over parole, and no law yet regulated the consultants and former board members who lobbied for prisoners.
A special review panel took up his file in September 1989. Chris Mealy, a board member, cast the deciding vote. "I wish that I could take it back," he later told Cartwright. McDuff walked out on October 11, 1989, and reported to a parole officer in Temple. Larry Pamplin, the Falls County sheriff, told people he would kill again. "The most frustrating part," Pamplin said, "is that we knew he was going to kill someone." In July 1990 McDuff was charged with a misdemeanor, making a terroristic threat, and was returned to prison in September; the district attorney dropped the charge, a parole hearings officer reinstated his parole, and he was released again on December 6, 1990. In the spring of 1991 he enrolled at a technical college in Waco. Cartwright reports that police did not pursue McDuff seriously at the time.
On May 1, 1992, the television program America’s Most Wanted aired the case. A viewer in Kansas City, Missouri, recognized the man known there as Fowler, who worked on a city garbage truck, and McDuff was arrested on May 4. He was tried in Harris County on a change of venue and convicted of the capital murder of Melissa Ann Northrup, 22, and sentenced to death. He was also convicted of the capital murder of Colleen Reed, 28, before her death could be confirmed. Investigators attributed the deaths of Brenda Thompson, Regenia Moore and Valencia Kay Joshua to him, and he was never tried for them; lawmen read 14 names of "known victims" at a memorial in 1998. Texas executed him by lethal injection at Huntsville on November 17, 1998, at 52. A panel of the Fifth Circuit refused him a stay that same day.
Cartwright argued in 1992 that McDuff was not simply a killer who had fallen through a crack in the system. The case led to a perjury conviction for a former parole board chairman and to changes in how Texas paroles violent offenders, according to Texas Monthly.
Faryion Wardrip killed five young women in North Texas between December 1984 and May 1986: four in and around Wichita Falls, and one in Fort Worth. For years only one of the deaths was solved. In May 1986, days after killing Tina Kimbrew, 21, Wardrip called the police from a motel in Galveston and confessed. He pleaded guilty to murder and received 35 years. The other four cases stayed open, worked separately by three agencies with no reason to think they were connected to each other or to him.
He spent about 11 years in the Texas prison system. His disciplinary record, introduced by the state at his 1999 trial, showed two infractions in that time. Records gathered later for his federal habeas case showed that he took classes in art, horticulture and construction, passed the GED, and wrote sports articles for a prison newsletter. Tina Kimbrew’s parents took part in a Victim Services program that allowed crime victims to meet an offender, with both sides' agreement. The Dallas Observer reported that the meeting took place about 11 years after the sentence, when his release had become likely, and lasted five hours. Her father offered him help at the end and told him to call if he saw himself headed for trouble after his release. On December 11, 1997, Wardrip left prison on what the Texas Department of Criminal Justice records as mandatory supervision. The federal courts call it parole.
He settled in Olney, Texas. The Observer reported that his father helped him get a job at a door and screen factory, and that he sang in a church choir, taught Sunday school, married a woman from the congregation and told co-workers he planned to study for the ministry. He wore an ankle monitor. His employer and his parole officer later testified at his 1999 trial about his good conduct.
In early 1999 John Little, an investigator for the Wichita County district attorney, picked up the old files and came upon Wardrip’s name close to several of them. A neighbor of Ellen Blau, Wardrip had also worked at the hospital where Toni Gibbs worked, and had lived about a block and a half from the place where Terry Sims was killed. Little followed him for days and finally took a coffee cup he had thrown away. DNA from the cup matched evidence from the killings of Sims and Gibbs; a state expert put the chance of a random match at about one in 3.23 quadrillion. Wardrip was arrested in Wichita County on February 13, 1999, on capital murder warrants. In recorded statements he confessed to the Sims and Gibbs killings, to the killing of Ellen Blau, and to a Fort Worth killing that no one had linked to him, the death of Debra Taylor.
The capital murder case over Terry Sims, 20, was tried in Denton County on a change of venue. Wardrip pleaded guilty, against his lawyer’s advice, and left the jury to decide only punishment. After five days of testimony it concluded that he had acted deliberately, would be a continuing threat and that no mitigating circumstance called for a life sentence. Judgment was entered on November 5, 1999, and he arrived on death row on November 9. Life sentences for the deaths of Gibbs, Taylor and Blau followed, reported as consecutive. A federal judge set the death sentence aside in 2010; the Fifth Circuit reinstated it in 2020; and on May 19, 2026, the district court denied his remaining claims and granted a certificate of appealability on two issues. No change in Texas release policy has been recorded as following from his case.
Coral Eugene Watts confessed in 1982 to killing 13 women, 12 of them in Texas and one in Michigan. He was 28, a mechanic for Houston’s transit authority, and had been arrested in Houston on May 23, 1982, after an assault on two women. Prosecutors had no evidence tying him to any killing. District Attorney John Holmes said his office had "not a stitch of evidence." What it wanted was his information and a sentence equal to life.
The agreement that followed gave Watts immunity from murder prosecution for the killings he confessed to, in exchange for a guilty plea to burglary with intent to commit murder and a sentence of 60 years. Judge Douglas Shaver accepted it because there was no evidence to convict Watts of murder and the police needed his help. Shaver said he would recommend that Watts never be paroled, though he would be eligible after 20 years; "sad to say," he said, 60 years was the most the evidence allowed. UPI called it "a very difficult plea bargain." The families of the women he named gained answers. He never stood trial in Texas for any death.
The bargain had a second effect on a man named Howard Mosley. A Galveston County jury had convicted Mosley of attempted murder in July 1982 and he had been sentenced to life. A month later Watts confessed to an assault matching the one Mosley was convicted of. Mosley was granted a new trial on August 17, the charge was dropped, and he was released on September 2, 1982. The National Registry of Exonerations lists the case.
The bargain held for more than two decades and then began to slip. A Texas appeals ruling in 1989 deleted a deadly-weapon finding from the sentence, and with the state’s mandatory supervision law and good-time credits his release date moved to 2006. Relatives of his Houston victims, among them Lawrence Fossi, who spent much of the next two decades fighting to keep him in prison, campaigned against it. Michigan, which had refused to join the 1982 agreement, went back to its own unsolved cases. In 2004 an Oakland County jury convicted him of the first-degree murder of Helen Dutcher, 36, in Ferndale in 1979; a witness who had seen her assailant in 1979 called police again after a television appeal. He was sentenced to life without parole on December 7, 2004. In 2007 he was convicted in Kalamazoo of the 1974 murder of Gloria Steele, 19, and received a second life term. He died of cancer in September 2007, a little more than a week later. Those two Michigan verdicts are the only murder convictions in his record.
Clifford Olson was released from prison on September 7, 1980, on mandatory supervision. He had spent most of his adult life in custody. The Canadian Press gives his first sentence, in 1957, as nine months for burglary, and reported that he escaped at least six times. Between November 1980 and July 1981, around Vancouver, he killed 11 children and young people, three boys and eight girls, the youngest nine and the oldest 18.
The eleven killings fell in several police jurisdictions around Greater Vancouver, some policed by the RCMP and some by municipal forces. The Canadian Press noted in a 2011 review that police had met him hours before one of the killings and that calls for an independent inquiry were ignored. He was arrested on Vancouver Island on August 12, 1981. His trial opened on January 11, 1982, on 10 counts of first-degree murder; within three days he admitted all 11. Justice H.C. McKay sentenced him to 11 concurrent life terms with no parole eligibility for 25 years and recommended that he never be released.
Days later the public learned that police and the British Columbia attorney general had agreed to pay $100,000, held in trust for Olson’s wife and infant son, for his help in locating the victims. In 1984 the families of seven of the dead sued to have the trust declared fraudulent. Justice William Trainor ruled that the families could claim against the money; the B.C. Court of Appeal reversed in March 1986, and the Supreme Court of Canada refused leave to appeal. The money went to Olson’s wife and son. A former attorney general testified that he had agreed to the payment only because police told him a conviction was unlikely without it.
The policy that came out of the case was narrow. Police said years later that the frustration of the Olson investigation led to a new computer system for tracking violent offenders, the Canadian Press reported. CBC News also listed a police tracking system among the changes. The other legacy came from his own applications. Under Section 745 of the Criminal Code, the "faint hope" clause added in 1976, a person serving life for murder could ask a jury after 15 years to reduce the time before parole eligibility. Parliament amended the clause in January 1997 to bar people convicted of multiple murders after that date and to require unanimous jury approval, but the changes could not apply to Olson retroactively. A jury in Surrey, British Columbia, rejected his application in August 1997. The parole board denied him in 2006 and in November 2010. He died of cancer on September 30, 2011, at 71, in the health care centre of the federal prison at Sainte-Anne-des-Plaines, Quebec.
Guy Georges was sentenced in Paris on April 5, 2001, to life imprisonment with a minimum term of 22 years for the murders, with rape, of seven young women between 1991 and 1997. French lawmakers and broadcasters call him "le tueur de l’Est parisien," after the part of the city where the killings took place.
He had been in the French child welfare system as a boy and in prison as a young man. Newsweek reported that from 1979 he assaulted a series of young women: a one-year sentence in an Angers prison for offenses in 1980, 18 months after June 1982, and ten years after February 1984. Near the end of that ten-year term he was granted day release. On the evening of January 24, 1991, he did not return to prison. Newsweek places the death of Pascale Escarfail, 19, the first victim, on that night; the National Assembly’s report dates the first killing to January 1991. He was formally released on April 4, 1992. The six women killed after her were Catherine Rocher, Elsa Benady, Agnès Nijkamp, Hélène Frinking, Magali Sirotti and Estelle Magd.
For most of the 1990s, no one treated the deaths as the work of one man. The National Assembly report says that the murders in eastern Paris and other murders committed in the city were handled by two investigative teams and that no link was made between them. Investigators had a DNA profile from the killings, known by the label SK1, and no national file to compare it with. His lawyer at the trial, Frédérique Pons, said in a 2015 interview that he presented himself to the police in 1995 in connection with the inquiry and was cleared at first. The parliamentary report records that in August 1995 he was convicted of a sexual assault and that no link was made between him and the Paris murders. He was arrested in March 1998; Newsweek gives the date as March 27, in Montmartre, though the Assembly report ties the arrest to a composite sketch and a survivor’s recognition of his photograph, with a match made by hand in a laboratory at Nantes.
Of all the cases here, his shows policy changing fastest and most visibly. Law no. 98-468 of June 17, 1998 created the Fichier national automatisé des empreintes génétiques, the FNAEG, to hold the DNA profiles of people convicted of listed sexual offenses. A deputy asked the Interior Ministry in November 1998 why no national file yet existed, citing the arrest of "the murderer of eastern Paris" by genetic comparison. The decree that put the file into operation came on May 18, 2000, two years after the law. In December 2002 a report by the deputy Marc Le Fur opened its case for the file with the Georges affair, saying that a central file, of the kind Britain had had since 1995, would have identified him more quickly and saved the lives of his last two victims.
The trial was held in March and April 2001. He had confessed to the police, but at trial he pleaded not guilty to all charges. Pons said that when she first met him he maintained he was not the killer, and that the turning point came when he was asked a simple question about which hand he used and mimed holding a knife. After that, in March 2001, according to the Assembly report, he admitted seven murders and four other assaults committed between 1991 and 1998. Since 2020 he has been entitled to apply for conditional release.
Levi King was 23 when, over about a day at the end of September 2005, he killed five people in two states. In 2003 he had been sentenced in Missouri to 14 years in prison for second-degree arson and burglary. He was paroled after serving about 17 months, according to NewsChannel 10 and The Pampa News, and in July 2005 was released to a halfway house in St. Louis. CBS’s 48 Hours later put his time served at less than three years.
In late September he left the halfway house and did not return. NewsChannel 10 reported in 2006 that he left seven days before the Texas killings, in violation of his parole, and that authorities were not notified. KOMU said he walked out a week before his arrest. On September 29 he killed Orlie McCool, 70, and his daughter-in-law Dawn McCool, 47, in rural Pineville, McDonald County, Missouri. Early the next morning, hundreds of miles away near Pampa in the Texas Panhandle, he killed Brian Conrad, 31, his wife Michell Conrad, 35, who was about six months pregnant, and her son Zach Doan, 14. Michell Conrad’s 10-year-old daughter survived. That night King was arrested in El Paso, Texas, driving Orlie McCool’s pickup. He had no known link to either family.
Missouri prosecutors announced in 2006 that they would seek the death penalty, and a Gray County grand jury indicted him for capital murder in March 2006. On April 18, 2008, he pleaded guilty to two counts of first-degree murder in Missouri; under the agreement he avoided a possible death sentence and received two consecutive terms of life without parole. The Texas trial opened in Lubbock on September 3, 2009, on a change of venue, and he pleaded guilty to three counts of capital murder, understanding that he could still be sentenced to death. The jury deliberated for nearly eight hours and could not agree unanimously. On October 6, 2009, he was sentenced to life without parole. One of the twelve jurors would not vote for death, Texas Monthly reported later.
After the verdict, Michell Conrad’s daughter, then 14, spoke to King in court. She told him she was still haunted by that night and that she forgave him. Brian Conrad’s mother said in 2010 that one man’s act had touched so many people that there were "too many victims to even count." No change in Missouri’s halfway house or parole practice was reported after the walk-away.
Lázaro Barbosa de Sousa was never tried for a killing, and every killing linked to him rests on police attribution. In the early hours of June 9, 2021, four members of one family were killed in Incra 9, a rural settlement in Ceilândia on the western edge of Brazil’s Federal District: Cláudio Vidal de Oliveira, 48, his wife Cleonice Marques de Andrade, 43, and their sons Gustavo, 21, and Carlos Eduardo, 15. Police attributed the killings to Barbosa, and about 200 officers from the Federal District and Goiás hunted him for 20 days through the farm country west of Brasília.
His record in the prison system explains the hunt. Correio Braziliense reported that in 2013 psychologists at the Papuda penitentiary wrote a criminological evaluation that recorded aggressiveness, impulsiveness and emotional instability. They wrote that if he returned to the social setting he came from he "will probably return to offending," and they ruled out a move to the semi-open regime at that time. In 2014 the Federal District public prosecutor’s office supported his progression to the semi-open regime but without external benefits such as temporary release, writing that his "degree of dangerousness is high." A court approved the move that year.
In 2016 he was let out of the Federal District’s semi-open unit for the Easter furlough and did not come back. A warrant was issued in April 2016. In March 2018 Goiás civil police arrested him in Águas Lindas de Goiás, and on July 23, 2018, he got out of the jail there through a hole in the ceiling of his cell, the only one of six inmates to succeed, according to Metrópoles. He was also accused of a double homicide in Bahia, where the criminal court had issued a warrant, and was convicted in the Federal District of robbery and other offenses committed in 2009. The Bahia accusation never came to trial.
On the morning of June 28, 2021, police closed in on a wooded area in Águas Lindas de Goiás. By the police account he fired at officers, and they returned fire; he was taken to Hospital Municipal Bom Jesus, where he was declared dead. The governor of Goiás, Ronaldo Caiado, was among the first to announce that the fugitive had been captured, and shortly afterward officers confirmed that he was dead. Goiás police closed and archived the investigations linked to him, O Hoje reported in 2023. Days before his death, Congresso em Foco reported, the Chamber of Deputies had put on its agenda, with urgency, a bill to restrict the temporary release of prisoners. Whether it passed has not been reported.
The programs were different, and so were the men. McDuff was released under an order that put the system’s capacity ahead of a board’s judgment, and the sheriff of the county where he grew up said aloud that he would kill again. Wardrip left under a law that counts time served, and no one in the system had connected him to four unsolved deaths. Watts never got out, but a date was approaching, and it was that date, more than any new evidence, that sent Michigan prosecutors back to their files. Olson walked out of a program designed for supervision, and the Canadian Press noted that police had met him hours before one of the killings. King left a halfway house without anyone being notified. Georges did not come back from a day’s release, and France wrote a DNA law in the middle of his case. Barbosa did not come back from an Easter furlough, and the Brazilian Chamber of Deputies took up a bill to restrict such leave five years later, with the manhunt still on.
Whether any of these releases was an error depends on who is asked. Judge Shaver called 60 years the most the evidence allowed. A French deputy wrote that a central file would have saved two lives. A former British Columbia attorney general testified that he paid for information because police told him a conviction was unlikely without it. Mealy, who cast the deciding vote for McDuff, said he wished he could take it back.
