Oklahoma Businessman Claims Black Employee Buried Under Septic Tank 'Caused' His Own Death as Seventh Appeal Is Denied

An Oklahoma appeals court has reaffirmed the life sentence of Dan Triplett, a former city councilman, convicted for murdering his employee, Brent Mack, and hiding his body beneath a septic tank. In February 2023, Triplett received a sentence of life imprisonment without parole after being found guilty of first-degree murder. Despite filing seven appeals citing trial errors, a three-judge panel upheld his conviction, reinforcing his lifetime incarceration. Mack’s tragic disappearance led to shocking revelations through surveillance footage and forensic evidence, ultimately highlighting the horrific crime.
