A hair is a small thing to hang a verdict on. In the cases below, examiners compared hairs and carpet fibers under a microscope and told juries that a strand from a victim and a strand from a suspect were consistent or similar. The cases show what that kind of evidence could do. It helped to convict Wayne Williams in Atlanta, it helped to bring down a man in Dallas on hair alone, and in one case it was set out for a jury as a single red nylon fiber. The same cases also show where it failed, and what happened when science caught up with it.
One point needs saying at the start. Hair reviews and later DNA work challenged the testimony in several of these cases, but they did not overturn most of the convictions. Williams, Albright, Wood, Spencer and Legere stand convicted. Two exceptions come from the record itself. A Florida court ordered an acquittal in one of Bobby Joe Long’s cases, in part because hair and fiber comparison could not carry the weight the state put on it, and a Virginia man was pardoned after the same Arlington investigation that convicted Timothy Spencer.
Wayne Williams was convicted in February 1982 of murdering two young men, Jimmy Ray Payne, 21, and Nathaniel Cater, 27. A Fulton County jury returned the verdict after a trial of about nine weeks, and Judge Clarence Cooper sentenced him to two consecutive life terms. Both of the men he was convicted of killing were adults. He was never tried for the deaths of the children and teenagers on the Atlanta task force list, and he has always said he is innocent.
The core of the state’s case was fibers and hairs. Three experts, Harold Deadman of the FBI, Larry Peterson of the GBI and Barry Gaudette of the Royal Canadian Mounted Police, compared fibers and animal hairs from the victims with material from Williams’s family, the cars they used and the family’s German shepherd. They described violet acetate and green cotton fibers matching a bedspread, green nylon fibers matching a bedroom carpet, yellow fibers matching a blanket, fibers from a station wagon, and dog hairs consistent with the family dog. The carpet fiber was traced to a line made by West Point Pepperell. The experts reported seven associations with Payne and six with Cater. Some fibers from the victims were lighter in color than the samples from the Williams family, which the state explained as the effect of water. Prosecutors were allowed to give the jury mathematical probabilities for the fiber matches. Gordon Miller called it "probably the greatest fiber case ever tried."
Judge Cooper also admitted evidence about ten other deaths on the task force list, under Georgia’s rule allowing similar transactions to be used to prove identity. Williams was not charged with any of them. The defense fought the fiber evidence. Its own expert, Charles Morton, complained of poor access to the material, though the Supreme Court of Georgia later noted that the defense experts had been offered the fibers at least twice and had not examined them. Williams testified in his own defense, and so did his parents. "It was the fibers, that was all I saw," Binder said after the verdict. "It sure wasn’t the witnesses."
The Supreme Court of Georgia affirmed on December 5, 1983. It held that it was for the trial judge to decide whether the fiber comparisons were competent scientific evidence and that he had not erred in admitting them, that probability testimony was allowed, and that the experts' undocumented experiments and notes were not scientific reports that had to be disclosed. Justice George Smith dissented. He found that the fiber evidence fell short of scientific certainty and that the pattern evidence should never have been admitted.
The doubts came in two waves. In February 2004 Williams filed a 146-page federal petition arguing, among other things, that the fibers were not identical to those from his family and would not survive scientific scrutiny. His lawyer Jack Martin said, "We believe he’s innocent." A GBI spokesman, John Bankhead, answered: "They got the right guy." The district court denied the petition in February 2006, and on November 8, 2007, the Eleventh Circuit held that his remaining claims were in substance a second habeas petition that the district court could not hear without its permission.
In 2007 testing of hair from one of the other cases attributed to Williams went further than the fibers had. The Associated Press reported on August 1, 2007, that mitochondrial tests on eight hair fragments from the case of an 11-year-old matched a mouth swab from Williams at every position but one, and that he "cannot be excluded as the source." The sequence occurs in 3.4 percent of the Black population in the FBI’s database. His lawyer, Lynn Whatley, said he was disappointed the tests were not more definite. Mitochondrial DNA is passed down the maternal line and does not single out one person, and no court has tried Williams for that death.
Then came the review of the discipline itself. In 2013 the Justice Department wrote to Whatley as part of a national review of FBI microscopic hair analysis in cases before 1999, carried out with the FBI, the Innocence Project and the National Association of Criminal Defense Lawyers. The letter said that one or more of 13 examiners whose work might not have met professional standards was believed to have been involved in Williams’s prosecution, 11Alive reported. Fulton County District Attorney Paul Howard said in a statement that the federal review had found no problems with the testing, that the evidence in question was not material to the verdict and was not used at trial, and that it would not affect any appeal. Jack Mallard, a prosecutor at the trial, said the hair evidence had played a minor role and the fibers alone would have convicted. Whatley said he planned a final appeal. No ruling from such an appeal was reported. In November 2019 the State Board of Pardons and Paroles denied Williams parole again and set his next consideration for November 2027.
Between March and November 1984 at least eight women were killed in and around Tampa, Florida. The man responsible, Robert Joe Long, known as Bobby Joe, was identified because a 17-year-old girl he had abducted and released remembered a maroon Dodge Magnum with a red carpet and the word "Magnum" on the dashboard, and the sound of a bank machine. Within two weeks a bank record had produced his name. Fibers played their part from the start: on November 14, 1984, the FBI laboratory reported that fibers from the girl’s clothing matched the red, lustrous, trilobal nylon carpet fibers associated with the murder cases. Detective Lee Baker later told a jury that each case had produced the same kind of evidence, a red carpet fiber with a three-lobed cross section. Long was arrested in Tampa on November 16, 1984.
On September 23, 1985, Long pleaded guilty to eight counts of first-degree murder. The pleas made the hair and fiber evidence irrelevant to those eight convictions, and that is why the part of his story that mattered for the science came from a ninth case. Virginia Johnson was killed in Pasco County, and Long was tried for her murder three times, with the venue moved, and convicted three times. The center of the third case, tried at Ocala before Judge Charles Cope beginning on January 21, 1994, was the FBI hair and fiber examiner Michael Malone. He testified that two bleached blond hairs from the sweepings of Long’s car were consistent with Johnson’s hair, and that a single red trilobal nylon fiber recovered in the investigation had the same characteristics as the carpet in Long’s car. On cross-examination he agreed that hair comparison does not prove identity and that the fiber type was the most common carpet fiber made. The jury convicted Long and recommended death by 7 votes to 5.
On March 6, 1997, in Long v. State, 689 So. 2d 1055, the Florida Supreme Court reversed for the third time and did not order another trial. Circumstantial evidence, it said, must be "inconsistent with any reasonable hypothesis of innocence." Hair comparison could not make a positive identification, and there was no proof that the single fiber could have come only from Long’s car. No witness had seen him with Johnson. The evidence raised a strong suspicion, the court said, but suspicion was not enough. It directed the trial court to "enter an order of acquittal for this crime."
Malone’s methods were questioned later, in other cases. In a 2017 decision in another capital case, Duckett v. State, the Florida Supreme Court described a 2014 Justice Department review of his work that found some of his statements "exceeded the limits of science and were, therefore, invalid." Long’s eight murder convictions rested on his guilty pleas, not on Malone. He was executed at Florida State Prison on May 23, 2019, for the murder of Michelle Simms.
Between December 1990 and March 1991 three women in the Oak Cliff section of south Dallas were killed: Mary Lou Pratt, Susan Beth Peterson and Shirley Williams. On March 22, 1991, police arrested Charles Albright, an Oak Cliff man known to his friends as a gentleman, a churchgoer and a gifted amateur painter, but who also had a record going back to his teens.
In December 1991 a Dallas County jury convicted him of the murder of Shirley Williams and he was sentenced to life. The case rested largely on hair comparison. Texas Monthly called it the first murder conviction in the history of the Dallas County district attorney’s office to rest on hair evidence alone. The Dallas city crime lab reported that hairs recovered in the investigation of the three women were similar to Albright’s, that hairs on blankets in his pickup truck were said to match Pratt and Peterson, and that hairs in his vacuum cleaner were said to match Williams. Prosecutors also relied on testimony from other women. Texas Monthly cautioned in 1993 that hair is not as conclusive as fingerprints and that other gray-haired men could have similar hair.
Toby Shook, a 33-year-old assistant district attorney, led the prosecution. His case rested on the hair evidence and on the tip that had pointed police to Albright. Brad Lollar defended him, called the evidence flimsy and circumstantial, and told the jury that the likelier culprit was a truck driver who had rented a house from the family. That man was never charged. A woman who had earlier identified him told the jury that she had never been with him and that she had been pressured. The jury found him guilty, and his companion collapsed in the courtroom. Albright never testified and never confessed. In prison he suggested that the forensic lab, not he, was responsible for what had been found.
The hair came back in 2020. Reporting that September, KRLD said the conviction integrity units of the Dallas County District Attorney’s Office and the Dallas County Public Defender’s Office had recently sent hair samples from the case to a laboratory. According to Lollar, the lab reported that the samples were not human hair. "These are dog hairs," he quoted the lab as saying. No court action on the results has been reported. Albright died in state custody in 2020, at 87, and he was never tried for the deaths of Pratt and Peterson. The reports differ on his sentence: KRLD described life without parole and Texas Monthly a life sentence.
On the night of Saturday, October 15, 1977, Christine Eadie and Helen Scott, both 17, ended an evening out in Edinburgh at the World’s End pub on the Royal Mile. For almost 30 years no one was charged. When a man finally stood trial in 2007, the judge stopped the case at the end of the prosecution evidence and acquitted him.
That man was Angus Sinclair, a Glasgow man who was already serving a life sentence. He had been convicted in 2001 of the 1978 murder of Mary Gallacher after advances in DNA work on a hair linked him to her killing, the Scotsman reported. In April 2004 scientists tested a stain on Helen Scott’s coat and found a match to Sinclair, with odds of a billion to one against the DNA coming from anyone else. Detectives also traced the upholstery of Sinclair’s van, from old photographs, to a conversion company in Devon, and fibers from Helen’s coat matched it.
Sinclair went on trial at the High Court in Edinburgh in August 2007, before Lord Clarke. The Crown relied on two main strands: the DNA in the stain on the coat, and more than 50 fibers on the coat that matched the upholstery of his Toyota Hiace caravanette. The prosecution did not lead the low-level DNA evidence from the clothing used in the killings, the Crown Office later said. At the close of the prosecution case the defense made a submission of no case to answer. On September 10, 2007, Lord Clarke upheld it and acquitted Sinclair. The jury never considered a verdict. "There was no forensic evidence to link the accused to the items used to kill the girls," the judge said, and he was not satisfied that the evidence the Crown relied on could overcome "that absence of crucial evidence." There was no right of appeal against an acquittal by a judge.
Fifty fibers had not been enough, and the lesson was not that fibers are weak but that a trace on a coat is only as good as the thing it is said to connect. The law changed. Under the Double Jeopardy (Scotland) Act 2011 a person acquitted can be tried again when new evidence emerges, and Sinclair became the first man in Scotland tried a second time for the same crime. In November 2014 a jury convicted him of the murders of both girls, with other charges, and Lord Matthews set a punishment part of 37 years, the longest a Scottish court had imposed. His appeal against sentence was refused on March 24, 2016, and he died at HMP Glenochil on March 11, 2019.
David Leonard Wood has been under a sentence of death in Texas since 1993 for the deaths of six girls and young women from El Paso who died in the spring and summer of 1987. A Dallas jury, hearing the case after it was moved from El Paso because of publicity, convicted him of capital murder in 1992. The Associated Press reported that he was the first defendant prosecuted under the Texas provision that makes it a capital crime to murder more than one person during the same scheme or course of conduct. He has always denied the killings.
The case that went to trial rested on four kinds of evidence: the accounts of people who saw victims getting into vehicles like Wood’s, the testimony of a woman who survived, fiber evidence, and two men who had shared cells with Wood. The fiber evidence came from a vacuum cleaner bag that Wood and his girlfriend had left behind when they moved out of a rental. A forensic chemist testified that orange fibers on the clothing of one victim matched fibers in the bag, and Associated Press reporting in 2009 identified that victim as Desiree Wheatley. Wood’s girlfriend testified that he owned a burnt orange blanket and some shovels and kept them in his pickup.
The two cellmates were Randy Wells and James Carl Sweeney Jr. Wells testified that Wood had described the killings to him. Sweeney testified that Wood showed him newspaper clippings about the El Paso murders and admitted that he was the one who had committed them. The Marshall Project reported in 2025 on the challenge to that testimony.
The fibers were not the focus of Wood’s later litigation, which has concentrated on what else could be tested. A 2011 motion listed 69 items, mostly clothing and other objects. A 2015 motion asked the court to test hair, saliva and blood samples that police took in 1987 from S.M., a man questioned about the murders whom Wood’s lawyers call an alternative suspect; Wood said the samples had been sent to the state crime lab and never tested. A 2017 filing laid out a spreadsheet of 142 entries, of which Wood’s lawyers said 86 met the legal standard for testing and 15 had been lost or destroyed by the State. Judge Richardson repeatedly complained about the pace. In March 2017 he said, "I don’t think you get to come back to the table over and over and drag this out forever."
The detectives who built the case rejected the challenge. John Guerrero, who had served on the task force, told KVIA that witnesses had picked Wood out of photo lineups and that he had never interviewed Wells or Sweeney himself. "There was no doubt in my mind, or any of us that worked those cases, that he is the killer," he said, and he called the claims "grasping at straws to save his life."
An execution set for March 13, 2025, was stayed on March 11 by the Texas Court of Criminal Appeals, which sent the case back to the trial court on July 30, 2025. On September 4, 2026, visiting Judge Dick Alcalá granted new DNA testing. The conviction itself has not been disturbed, and Wood was on the Texas death row list updated March 12, 2026.
Timothy Wilson Spencer was convicted of four capital murders committed in Virginia in the fall of 1987: Debbie Dudley Davis and Dr. Susan Hellams in Richmond, a 15-year-old girl, Diane Cho, in Chesterfield County, and Susan Tucker in Arlington. He had been released to a Richmond halfway house only weeks before the first killing. His 1988 Arlington trial is described as the first capital murder conviction in the United States built on DNA evidence. Hair figured in the Arlington investigation before his name ever came up.
The Tucker case resembled the 1984 Arlington killing of Carolyn Hamm, for which another man had been convicted. That man, D. V., had entered an Alford plea to second-degree murder and burglary on February 3, 1985, the day before his trial was to begin, a plea in which a defendant does not admit guilt but accepts that the evidence could convict him. Other evidence pointed away from him: biological evidence did not match his blood type and shoe impressions did not match his shoes. But a forensic analyst reported that hair was microscopically similar to his. He was sentenced to 35 years. Detective Joe Horgas, called to the Tucker case, visited D. V. in prison on December 7, 1987. D. V. withdrew his confession, and Horgas told the warden, according to Arlington Magazine, "I don’t think [he] belongs here." The Hamm killing was later attributed to Spencer by investigators, though Spencer was never charged with it. D. V. was pardoned by the governor.
At Spencer’s Arlington trial three scientists testified for the prosecution about DNA: Dr. Richard Roberts of Cold Spring Harbor Laboratory, Dr. Kenneth Kidd of Yale and Dr. Michael Baird of Lifecodes. Spencer conceded on appeal that he could find no expert to dispute the technique. The prosecution also presented hair comparisons and glass fragments that matched a broken basement window. On July 16, 1988, after about six hours of deliberation, the jury found him guilty and fixed his sentence at death. In the Davis case hairs consistent with Spencer’s were presented along with the DNA evidence. In Diane Cho’s case the conventional DNA test failed because the sample held too little DNA, and the prosecution turned to a newer method, PCR amplification, which identified a genotype found in about 5 percent of the population; combined with blood and enzyme results, the profile occurred in less than 1 percent. A hair was microscopically similar to Spencer’s. Dr. Edward Blake and Dr. Haig Kazazian testified that the method was reliable, and their testimony was not rebutted.
Spencer was executed in Virginia on April 27, 1994. In 2026 his case was one of eight executions named in a state review of the work of a forensic serologist, Mary Jane Burton. No findings had been reported as of August 2026. That review concerns serology records, not hair, and it shows how the story keeps moving after the sentence.
Between February 1976 and March 1977 four children were abducted from the suburbs just north of Detroit, in southern Oakland County, Michigan, and killed: Mark Stebbins, 12, Jill Robinson, 12, Kristine Mihelich, 10, and Timothy King, 11. No one has been charged. The investigation was described at the time as the largest of its kind in the United States, and in February 2026 the Michigan State Police said the case remains open. Police and prosecutors have said it is not established whether one person or more than one was responsible.
Hair has produced the only scientific thread, and it has been cut in several directions. In August 1999 L. Brooks Patterson, who had been the county prosecutor at the time of the killings, organized an effort to obtain DNA from a dead man, D.N., then regarded as the prime suspect. The sample was compared with a hair connected to one of the victims. It did not match, and the Associated Press reported in 2006 that the lead had collapsed in November 2000.
In May 2011 WDIV reported that police documents described white animal hairs, believed to come from a dog, on all four children, and three hairs on Kristine Mihelich that had never been disclosed. One hair from her blouse was reported to be a mitochondrial DNA match to J.G., a man then living in Kalamazoo who had been 16 at the time of the killings. Mitochondrial DNA is passed down the maternal line and cannot single out one person; the match meant the hair came from him or a male relative on his mother’s side, and police documents said it narrowed the source to about 1 percent of the white population. He was not charged. In February 2012 he told WDIV, "I’m not guilty," and denied any involvement.
On July 17, 2012, Oakland County Prosecutor Jessica Cooper announced what she called the very first piece of evidence linking two of the killings. FBI testing found that hairs recovered in the investigations of Mark Stebbins and Timothy King came from the same person. A matching hair had also been recovered from a 1966 Pontiac owned by A.S., then 70, a man serving life sentences for unrelated offenses. Cooper was careful about what the evidence showed. The hairs were not A.S.'s. She said he was not a suspect, that he often lent his cars to other people, and that investigators wanted to know who else had used the car and who spent time with him in the 1970s. WXYZ reported that in 2009 investigators discovered that human hair held by the State Police had been mislabeled as animal hair, and that a request for a review of all the physical evidence turned up an untested hair from Timothy King that also matched. Prosecutor Walton later put the strength of the mitochondrial match at about 1 in 1,814 people. A.S. died in prison in June 2026.
The prosecutor later cautioned against several beliefs that had become fixed in public accounts, WXYZ reported in 2020. It is not established that one person abducted and killed all four children. Carpet fibers from the children did not show that they were held in the same place; investigators could say only that the fibers were of the same color, not the same dye lot, maker or location. The genetic evidence is old mitochondrial evidence, not the nuclear DNA that has solved other cold cases. The hairs remain the only published scientific link between any of the cases, and they connect only the two boys. None of the men publicly named over five decades has been charged.
Allan Legere was convicted of five murders in New Brunswick. The first was the killing of John Glendenning, a storekeeper at Black River Bridge, in June 1986. A jury found Legere guilty of second-degree murder on January 22, 1987, and he was sentenced to life imprisonment with no eligibility for parole for 18 years. The Crown’s case was that Legere was the "third man" in the Glendenning robbery. Evidence included an oral statement Legere made to an RCMP sergeant and hair samples taken from him in June and July 1986.
The hair samples were the first test of how far the law would stretch for hair. On August 5, 1988, the New Brunswick Court of Appeal dismissed his appeal. It found that the police had infringed his Charter rights when they took the 1986 samples, the first without consent and the second under a search warrant that could not authorize it. It declined to exclude the evidence, because the officers had acted on Crown advice and on the case law of the time, and because the hair evidence was important to identification.
In May 1989 Legere escaped custody. Over the next seven months four more people were killed in the Miramichi region: Annie Flam, 75, Donna Daughney, 45, Linda Daughney, 41, and Father James Smith, 69. In early fall 1989 the RCMP’s Central Forensic Laboratory in Ottawa opened for DNA casework. According to Jack Walsh, one of the Crown prosecutors, its first comparisons matched biological material from the Flam and Daughney cases with DNA in hair that police had taken from Legere in 1986. Because the 1986 hair samples held only small amounts of DNA, they were combined with hair taken in 1989 for testing. On the evening of November 16, 1989, the RCMP publicly confirmed that DNA linked Legere to the killings. He was recaptured on November 24, 1989.
At his 1991 trial the DNA evidence was disputed. The defense expert, Shields, agreed that the samples matched. He argued that population structure in the region meant the odds were overstated and proposed a correction that would reduce a five-site match to about 1 in 11 million. His testimony that there was a high degree of inbreeding in the community drew public anger, according to Walsh. Kidd and Carmody answered him, and by the end, Walsh wrote, the dispute was only over how rare the matches were. A jury convicted Legere of four counts of first-degree murder on November 3, 1991, and he was declared a dangerous offender.
The Court of Appeal affirmed on December 16, 1994. It held that DNA typing should be judged like other scientific evidence, by its relevance and whether its results could reasonably be relied on, and that the trial judge had been right to admit it and to leave the statistics to the jury. It found that the 1986 hair samples had been taken illegally but should still be admitted. It found that the trial judge had erred in admitting only part of a statement by Legere, and that a pathologist’s opinion and part of the Crown’s jury address raised problems, but held that these errors caused no substantial wrong or miscarriage of justice. Legere went to the Supreme Court of Canada without a lawyer, and his application was dismissed. Parole was refused on January 13, 2021, and again in a decision reported on December 22, 2025. He died in custody at Edmonton Institution on March 9, 2026.
The cases ask different questions of the same material. In Atlanta, fibers were the case and the hair was an afterthought that a federal review later flagged; the conviction survived, on the strength, the prosecutor said, of the fibers alone. In Dallas, hair carried a conviction and was later described, by a defense lawyer, as dog hair, with no court ruling on that claim. In Edinburgh, more than 50 fibers did not persuade a judge that a man was tied to the killings, and DNA and a change in the law did. In Florida, a single fiber and two hairs were held too thin to sustain one conviction. In Virginia, microscopic hair similarity formed part of the case against a man who was later pardoned, and DNA carried the case against Spencer. In Michigan, mitochondrial hair is the one scientific link in a case that has not been solved.
Bite-mark comparison, another courtroom discipline that was later reviewed, followed a similar arc. For hair and fiber the review is still going on. The convictions largely stand, and the testimony that supported them has been reviewed.
