Gregory N. Bias, 41, of Tahlequah, has been sentenced to 30 years in federal prison for a series of serious child sex abuse and exploitation crimes.

The sentencing, delivered by Chief U.S. District Judge Ronald A. White, includes 360-month terms for multiple counts of aggravated sexual abuse and sexual exploitation of two children, as well as additional sentences for related offenses.

Bias’s extensive criminal activities, which involved the abuse and exploitation of children, were uncovered following a January 2022 arrest. This followed an alert from the National Center for Missing and Exploited Children (NCMEC) about illicit files being shared by an internet user in the Tahlequah area. Subsequent investigations by the Oklahoma State Bureau of Investigation (OSBI), Homeland Security Investigations (HSI), and the Federal Bureau of Investigation (FBI) revealed disturbing evidence of Bias’s crimes.

The evidence showed Bias not only abused children but also distributed and possessed illegal materials related to child sexual abuse. Alongside these charges, Bias was also convicted for possessing a firearm unlawfully, due to prior felony convictions.

On January 18, 2023, Bias pleaded guilty to 18 counts of the indictment.

His co-defendant, Leiloni B. Smith, 30, of Tahlequah and formerly of Vian, was found guilty by a federal jury on March 21, 2024, of eight counts of aggravated child sexual abuse among other charges. Smith is currently awaiting sentencing while in the custody of the U.S. Marshal Service.

U.S. Attorney Christopher J. Wilson commended the collaborative efforts of federal, state, and local agencies, highlighting the case as a significant step in safeguarding children and delivering justice. “This case underscores the relentless efforts of law enforcement to ensure that those who commit such heinous acts are held accountable,” Wilson stated.

The sentencing reflects the commitment of Project Safe Childhood, a national initiative aimed at combating child exploitation and abuse. As Bias begins his non-paroleable sentence, law enforcement continues to urge the public to report any information related to child exploitation to appropriate authorities.
