TULSA — A Mannford man was sentenced to 30 years in federal prison after investigators found more than 1,100 images of child sexual abuse on his electronic devices, including images he produced involving children under his care.
U.S. District Judge Sara E. Hill sentenced Thomas William Martin, 42, to 360 months in prison for production and possession of child sexual abuse material, according to the U.S. Attorney’s Office for the Northern District of Oklahoma.
Martin was also sentenced to lifetime supervised release and will be required to register as a sex offender following his release. Hill ordered him to pay $28,000 in restitution to victims.
Martin will remain in custody while awaiting transfer to the Federal Bureau of Prisons.
According to court documents and statements made during sentencing, the Broken Arrow Police Department began investigating Martin in 2024 after receiving reports that he had inappropriate contact with minor children.
Detectives executed a search warrant on Martin’s electronic devices and discovered 1,132 images depicting the sexual abuse of children, including infants, federal prosecutors said. Investigators also determined that Martin had taken sexually explicit images of children who had been placed in his care.
The material was submitted to the National Child Victim Identification System, which is managed by the National Center for Missing and Exploited Children. Investigators identified 97 children whose images had previously been reported and cataloged.
The identified victims live in the United States and other parts of the world. They were notified of the federal case and given an opportunity to submit victim impact statements to the court. Martin’s restitution payments will go directly to victims who requested compensation.
A probable cause affidavit filed during the investigation said the case began after a 15-year-old girl reported in October 2024 that Martin had sexually assaulted her in 2021.

The girl told investigators that Martin threatened to either turn himself in or kill himself. She also said Martin’s wife, who has since died, begged her not to report the alleged assault and promised Martin would stop drinking.
The girl came forward three years later after learning Martin was being investigated in Pawnee County over allegations involving other children, according to the affidavit.
Investigators also learned Martin had contacted a relative and requested the return of a hard drive. He allegedly instructed two other people to retrieve electronic devices from a Mannford residence and deliver them to a friend in Tulsa because the devices contained what he described as his “special movies.”
Police intercepted and collected the devices, which contained more than 1,000 images of child sexual abuse, according to investigators.
The affidavit said police identified three local victims in images found on the devices, including one child who was 8 years old when the images were created.
Investigators identified six alleged victims connected to Tulsa and Pawnee counties. Their ages at the time of the investigation ranged from 12 to 20, according to the affidavit.
Martin continues to face separate charges in Tulsa and Pawnee counties. Those charges remain pending, and Martin is presumed innocent in the state cases unless proven guilty.
The FBI, Broken Arrow Police Department, Pawnee County Sheriff’s Office and Homeland Security Investigations participated in the federal investigation. Assistant U.S. Attorney Ashley Robert prosecuted the case.
The prosecution was brought through Project Safe Childhood, a nationwide Department of Justice initiative that coordinates federal, state, local and tribal resources to investigate child exploitation, prosecute offenders and identify victims.
