DNA Genealogy Breakthrough Leads to Arrest in Multi-State Rape Case

Years-Long Investigation Concludes with Oklahoma Arrest

A sophisticated DNA genealogy investigation spanning multiple states has finally brought closure to two sexual assault victims after Hunter Mackey, 27, was arrested by the Oklahoma State Bureau of Investigation (OSBI) for first-degree rape in McLoud, Okla. on Feb. 17 . The arrest marks the end of a complex investigation that began in October 2021 and showcases how modern forensic technology can solve cold cases that once seemed unsolvable.

On Oct. 10, 2021, a female victim was sexually assaulted by a male suspect — now identified as Mackey — in North Texas. The victim told Fannin Co. Sheriff's Office investigators that she had met the man through social media. The suspect had picked her up in a sedan with Oklahoma registration, driven her to a location and sexually assaulted her . This detail about the Oklahoma license plate would prove crucial in connecting the case to a second assault across state lines.

Two months later, investigators were notified of a possible CODIS match between the Fannin Co. case and another similar sexual assault case out of Ardmore, Okla., being investigated by the Oklahoma Bureau of Investigation (OSBI) and the Ardmore Police Department . The Combined DNA Index System had flagged a potential connection between the Texas and Oklahoma crimes, setting the stage for an unprecedented multi-state collaboration.

Breakthrough Technology Overcomes Initial Setbacks

The investigation faced significant challenges when traditional methods failed to produce results. The Texas Rangers began coordinating with law enforcement in Oklahoma to conduct a familial search of the DNA samples from the Ardmore case through DPS' Crime Laboratory Division. Unfortunately, the familial search yielded no matches, and no arrests were made . For nearly three years, the cases remained cold despite the DNA connection.

The breakthrough came through federal funding and advanced technology. In August 2024, evidence from the Ardmore, Okla. case was sent for testing and comparison through DPS' Sexual Assault Kit Initiative (SAKI) program. The program is funded by the Department of Justice/Bureau of Justice Assistance (DOJ/BJA), which provides investigative funding for agencies across the United States to further unsolved sexual assaults and sexually related homicides .

Using SAKI grant funds, the sample was sent to BODE Technologies for DNA testing and genealogy research, which ultimately led to the identification of three brothers as potential suspects in September 2025 . This genetic genealogy approach, which has revolutionized cold case investigations nationwide, allowed investigators to narrow their focus dramatically.

Multi-State Collaboration Delivers Justice

The final phase of the investigation demonstrated the power of inter-agency cooperation. Upon further investigation and DNA comparison between the two sexual assault kits collected in the Fannin Co. and Ardmore, Okla. cases, law enforcement identified a positive match: Hunter Mackey . This confirmation linked Mackey definitively to both assaults, providing prosecutors with strong physical evidence across state lines.

He is currently being held in the Pottawatomie Co. Jail in Oklahoma , awaiting legal proceedings on the first-degree rape charges. The case represents more than just one arrest – it exemplifies how modern forensic science can deliver justice even when traditional investigative methods reach dead ends.

This investigation highlights the growing importance of federal programs like SAKI in solving sexual assault cases. As DNA technology continues to advance and databases expand, law enforcement agencies gain powerful new tools to connect crimes across jurisdictional boundaries. For the victims in Texas and Oklahoma, this technological breakthrough has transformed years of uncertainty into the promise of accountability and closure.
