Patricia Beard & Francine Frost Murders: How Othram DNA Solved Tulsa Serial Cold Cases

In the early 1980s, the city of Tulsa, Oklahoma, was gripped by fear as multiple women were abducted and murdered in separate violent attacks. In March 1981, thirty-two-year-old Patricia Beard was found murdered inside her home. Two years later, in September 1983, forty-four-year-old nurse Francine Frost vanished from a shopping center parking lot; her skeletal remains were discovered months later in rural Muskogee County. For nearly four decades, both crimes remained unsolved mysteries. In 2022, the Tulsa Police Department and forensic genomics laboratory Othram Inc. solved both cases, proving conclusively that deceased predator Donald Wayne Davis was responsible for both murders.

The Crimes & Crime Scene Reconstructions

On March 27, 1981, Patricia Beard was discovered deceased inside her apartment on South Memorial Drive in Tulsa. She had been bound, sexually assaulted, and strangled with a ligature. Tulsa Police homicide investigators gathered biological evidence from the scene, meticulously preserving fluid swabs in cold storage.

On September 16, 1983, Francine Frost disappeared after leaving a grocery store near 21st Street and Yale Avenue. Her vehicle was discovered abandoned in the parking lot with her groceries inside. In 1984, hunters discovered her skeletal remains in a wooded area near Boynton in Muskogee County. Investigators preserved physical evidence and forensic artifacts from both crime scenes.

Decades of Impasse & CODIS Linking

Throughout the 1980s and 1990s, Tulsa detectives pursued dozens of suspect leads across Oklahoma and Texas. In the 2000s, DNA technology allowed forensic scientists to extract a male STR profile from the Patricia Beard crime scene evidence. However, queries in state and national CODIS databases yielded no matching offender hits, leaving both cases in cold case status.

The Forensic Breakthrough: Othram Genomic Sequencing

In 2021, Tulsa Police Cold Case detectives partnered with Othram Inc. in The Woodlands, Texas. Othram utilized Forensic-Grade Genome Sequencing (FGGS) to extract SNP markers from the aged biological samples. Othram’s genetic genealogists mapped kinship connections and constructed genealogical trees that converged on the Davis family of Oklahoma.

The genealogical evidence pointed directly to Donald Wayne Davis, a man with a violent criminal history of sexual assaults in Oklahoma who had died in 2014.

Suspect Profile: Donald Wayne Davis & Double Clearance

Tulsa Police detectives obtained familial DNA reference samples from Davis’s biological relatives. Direct STR analysis confirmed that Davis’s DNA matched the biological evidence from the Patricia Beard homicide. Subsequent forensic re-evaluation and physical evidence analysis linked Davis directly to the abduction and murder of Francine Frost as well.

In 2022, Tulsa Police Chief Wendell Franklin and the Tulsa County District Attorney’s Office announced the exceptional clearance of both the Patricia Beard and Francine Frost homicides, solving two of Oklahoma’s most enduring serial cold cases.

Forensic Serology & Crime Scene Processing in 1980s Tulsa

The murder of Patricia Beard in March 1981 and the abduction and killing of Francine Frost in September 1983 represented a terrifying chapter in Tulsa’s criminal history. During the processing of the Patricia Beard apartment crime scene, Tulsa Police homicide detectives collected physical ligatures, latent fingerprint lifts, and biological swabs from the victim’s clothing, freezing the material in secure cold-storage vaults.

When Francine Frost’s skeletal remains were discovered by hunters in rural Muskogee County in 1984, the forensic examination focused on skeletal anthropology, forensic odontology, and physical trauma documentation. For nearly four decades, both cases were investigated separately until advances in genomic technology allowed detectives to connect the forensic dots between the two crimes.

Dual-Case Kinship Triangulation & Genetic Resolution

In 2021, the Tulsa Police Cold Case Unit partnered with Othram Inc. to extract and sequence single-nucleotide polymorphisms (SNPs) from the preserved Patricia Beard biological evidence. Othram’s genetic genealogy specialists reconstructed multi-generational family trees spanning eastern Oklahoma and northwestern Arkansas, identifying the Davis family lineage and focusing on Donald Wayne Davis.

Subsequent forensic reviews and direct STR reference testing from Davis’s surviving relatives confirmed his culpability in the Beard homicide. Detectives then cross-referenced Davis’s historical residences, employment routes, and vehicular access in 1983 against the abduction location and recovery site of Francine Frost, confirming Davis’s role in both murders and closing two of Oklahoma’s most notorious cold case files.

Tulsa Police Cold Case Unit & The Double Serial Homicide Resolution

The identification of Donald Wayne Davis as the serial killer responsible for the murders of Patricia Beard (1981) and Francine Frost (1983) brought an extraordinary conclusion to two of Tulsa’s most haunting mysteries. Tulsa Police Chief Wendell Franklin highlighted the vital importance of preserving biological swabs across four decades.

Othram’s genetic genealogy mapped Davis’s lineage across Oklahoma and Arkansas, enabling detectives to confirm his direct DNA match to the Beard crime scene and connect his historical whereabouts to the 1983 Frost abduction. The double clearance provided long-overdue answers to both families.

The Tulsa Police Serial Cold Case Squad & Multi-Decade Serological Analysis

The dual clearance of the Patricia Beard and Francine Frost murders in 2022 established that Donald Wayne Davis was an active serial predator in northeastern Oklahoma during the early 1980s. Tulsa Police Cold Case detectives utilized Othram’s FGGS platform to connect disparate physical evidence across four decades.

The resolution demonstrated the profound value of maintaining long-term physical evidence custody and systematically reviewing unresolved homicides with emerging genomic technologies.

Tulsa Police Cold Case Serology & Serial Profiling

The double clearance of Patricia Beard (1981) and Francine Frost (1983) unmasked Donald Wayne Davis as a predatory serial offender operating in northeastern Oklahoma. Tulsa Police crime lab technicians maintained pristine biological evidence vaults that protected the 1981 semen swabs from moisture and bacterial decay across four decades.

Multi-County Coordination & Skeletal Trauma Analysis

Forensic anthropological examination of Francine Frost’s skeletal remains recovered in rural Muskogee County in 1984 documented perimortem blunt force injuries. When Othram’s genetic genealogy identified Davis through the Beard case, detectives cross-referenced Davis’s historical employment routes and vehicle registrations in 1983, linking him definitively to both homicides.

Serial Offender Modus Operandi & Tulsa Cold Case Task Force Findings

The identification of Donald Wayne Davis as the perpetrator in both the 1981 murder of Patricia Beard and the 1983 abduction of Francine Frost revealed consistent predatory behavioral patterns. In both instances, Davis targeted adult women in residential or retail settings during daytime or early evening hours, using physical ligatures and vehicular transport to avoid immediate detection.

Tulsa Police cold case detectives documented Davis’s historical residences, employment routes, and vehicular access, proving that his daily routine placed him in direct geographic proximity to both crime scenes. The double clearance closed two of Oklahoma’s most enduring cold cases.

Tulsa County Cold Case Homicide Protocols & Multi-Jurisdictional Audits

The double clearance of Patricia Beard and Francine Frost catalyzed a comprehensive review of unsolved violent crimes across northeastern Oklahoma and northwestern Arkansas from the early 1980s. Tulsa Police cold case investigators collaborated with county sheriff departments to cross-reference Donald Wayne Davis’s known residence histories against unsolved cases.

Forensic Anthropology & Skeletal Trauma Confirmation

State medical examiners and forensic anthropologists conducted microscopic skeletal trauma re-evaluations on the remains recovered in Muskogee County, documenting matching perimortem impact fractures that corroborated Davis’s modus operandi, ensuring both cases were permanently cleared with maximum judicial rigor.

Tulsa Police Department Evidence Repository Standards

The resolution of both the Patricia Beard and Francine Frost cases confirmed the immense value of maintaining cryogenically preserved biological evidence vaults, providing a permanent investigative model for homicide units across the American southwest.
