Murder of Marlene Oakes
The murder of Helen Marlene Oakes remained a mystery for more than two decades after she disappeared in October 1980. Her husband, William Alexander Major, claimed that she had left their home and taken their children, but the circumstances surrounding her disappearance raised serious questions. Years later, a partial human skull discovered near the family residence was identified through mitochondrial DNA testing, providing a crucial breakthrough in the case.
The investigation revealed a disturbing history of family abuse, conflicting accounts, and efforts to conceal the truth. In the end, Major was convicted of Marlene’s murder, although his original conviction was overturned on appeal before he was convicted again.
Who Was Marlene Oakes?
Helen Marlene Oakes, born Marlene Oakes, was an American woman who lived with her husband, William “Bill” Major, and their two children, Donald and LaLana. The couple had been married for approximately nine years by the time she disappeared.
Their relationship had become complicated by allegations of abuse and other personal conflicts. Marlene had also developed a close relationship with Glen St. Hillaire, a mutual acquaintance who had once worked for Major and later lived in a mobile home on the couple’s property.
According to accounts documented during the investigation, Major reportedly encouraged the relationship between Marlene and St. Hillaire, although the circumstances surrounding their interactions were unusual. Major was also rumored to be involved with another woman.
Behind the complicated relationships, however, Marlene’s diary documented concerns that would become significant to the investigation.
The Diary and the Decision to Leave
Marlene kept a diary in which she recorded allegations that her husband had sexually assaulted their son, Donald. Major had previously been convicted in 1975 of molesting two boys, according to accounts of the case.
Marlene reportedly began making plans to leave the household with both children. She also discussed divorce with her sister and indicated that she would disclose the alleged abuse to her mother-in-law if Major changed his position on the divorce.
Recognizing the importance of her written records, Marlene gave her diaries to St. Hillaire so that they would be preserved. These documents later became part of the broader story of her disappearance.
The source material also reports that Major had threatened to kill Marlene if she ended their relationship and had described ways he could make her body difficult to identify. Such reports became especially significant when investigators later examined the discovery of unidentified remains near the family home.
Marlene’s Disappearance in October 1980
On October 11, 1980, Marlene and Major reportedly had an argument. St. Hillaire left the property to cool off. When he returned around midnight, he found the home in disarray.
Major had taken the children to a neighbor’s residence. He told St. Hillaire that Marlene had left and abducted the children, but the account did not hold up. St. Hillaire later learned that Major had misrepresented what happened and contacted police because he believed Marlene would not willingly abandon her children.
There were other troubling details. Investigators found no clear evidence that Marlene had prepared to leave the household. Her driver’s license remained at the residence, and there was no established explanation for her disappearance. Her vehicle was later believed to have been disposed of in the Ohio River, although the source material does not establish this as a confirmed fact.
Major told the children that their mother had abandoned them because of alleged problems involving drugs, alcohol, and prostitution. Authorities initially considered the possibility that Marlene had left an unhappy marriage, but searches of the property did not locate her.
Although her diary contained allegations that could suggest a motive, investigators initially lacked enough evidence to bring a murder charge. Marlene’s dental records were repeatedly compared with records from unidentified female remains, but no match was found.
The Discovery of an Unidentified Skull
On November 29, 1981, a hunter discovered a partial human skull approximately one mile from the Major residence. The skull had no teeth, making identification through dental records impossible.
Examiners determined that the remains belonged to a white woman believed to have been around 30 years old. The skull showed evidence of multiple gunshot wounds, and investigators also noted signs of dismemberment.
Marlene was considered a possible match, but authorities could not confirm that the remains belonged to her. Traditional nuclear DNA testing was eventually deemed impractical because the bone had deteriorated.
For years, the skull remained unidentified. Without a confirmed identity, investigators faced a major obstacle in establishing what had happened to Marlene.
Family Abuse Allegations and Major’s Arrest
In the years following Marlene’s disappearance, Major’s second wife, Pauline, reported allegations of sexual and physical abuse to police in 1984 after the children disclosed disturbing threats and behavior.
Major was arrested and convicted in 1985 in connection with abuse. He served 11 years of a 15-year sentence and was released in 1996. Following his conviction, Donald and LaLana went to live with their maternal grandmother.
Marlene’s mother had long suspected Major was responsible for her daughter’s disappearance. LaLana also sought answers as she grew older. She eventually confronted her father about the location of her mother’s remains, but he refused to tell her.
LaLana later took steps to investigate the case herself. She studied true-crime material, interviewed witnesses, and obtained access to investigative records through Boone County police when she was 20. Her efforts reflected the family’s continuing determination to learn what had happened to Marlene.
Mitochondrial DNA Identifies Marlene in 2001
A major breakthrough came in 2001, when LaLana submitted a DNA sample for comparison with the unidentified skull. Investigators used mitochondrial DNA, a form of genetic material that can be especially useful when conventional DNA testing is difficult.
Mitochondrial DNA provides less individual-specific information than some other forms of DNA analysis, but it can establish a maternal relationship. The test concluded that LaLana was maternally related to the person whose remains had been discovered.
The result confirmed that the skull belonged to Marlene Oakes, finally giving investigators scientific evidence linking the unidentified remains to the missing woman.
The testing cost nearly $20,000. Although the county initially declined to cover the expense, it eventually reversed its decision. Marlene’s sister had reportedly offered to use her retirement funds to pay for the test.
The identification transformed the case from a long-running disappearance into a homicide investigation supported by forensic evidence.
The Confession and Murder Conviction
Investigators also received information from Major’s father, who told authorities that his son had confessed to killing Marlene while in prison. At first, this statement alone was not sufficient to establish guilt, in part because of the strained relationship between the two men.
In March 2000, Major’s father allowed police to monitor a telephone call with his son. During that conversation, Major admitted guilt in the crime, according to accounts of the case. He was arrested, later confessed to police, and reportedly expressed no remorse.
Major was formally charged in July 2001. His defense argued that a stroke he had suffered in 1995 had left him delusional.
After a trial concluded on July 28, 2003, the jury deliberated for approximately 43 minutes before returning a guilty verdict. Major was sentenced to life in prison.
That was not the end of the legal proceedings. His initial conviction was overturned on appeal, and he was retried. He was convicted again and received the same life sentence.
A Case Remembered for Persistence and Forensic Evidence
The murder of Marlene Oakes illustrates the difficulties investigators face when a missing person cannot be located and physical evidence remains unidentified for years. At the beginning of the investigation, Marlene’s diary and the circumstances of her disappearance raised concerns, but authorities lacked the forensic evidence needed to establish what had happened.
The discovery of the skull provided a possible connection, yet its condition prevented immediate identification. Mitochondrial DNA testing eventually supplied the missing link, while witness information and Major’s statements contributed to the prosecution.
LaLana’s determination was also an important part of the case’s history. Her willingness to pursue DNA testing helped establish her mother’s identity and bring a long-standing family mystery closer to resolution.
Marlene Oakes disappeared in 1980, but her remains were not identified until 2001. The case ultimately resulted in a murder conviction that was upheld through a retrial after the original conviction was overturned.
Her story remains a reminder of the importance of preserving evidence, investigating allegations of abuse, and continuing to pursue answers even when a case has remained unresolved for decades.
