Woman Sentenced for Evidence Tampering
For Immediate Release
U.S. Attorney's Office, Northern District of Oklahoma
A Tulsa woman was sentenced today for three counts of Evidence Tampering, announced U.S. Attorney Clint Johnson. U.S. District Judge Gregory K. Frizzell sentenced Ashton Nikoel Mattingly, 31, of Tulsa to 144 months imprisonment, followed by 3 years of supervised release.
According to court documents, in Feb. 2021, Mattingly knew she was the target of a federal Grand Jury investigation. She instructed a third party to go into her home and remove a pill bottle so it would not be available as evidence in the investigation. Mattingly then instructed the third party to tamper with her social media account, attempting to disable the account. She then contacted a different third party instructing them to falsify that her cellphone was stolen and to request the service to be disabled. Mattingly admitted that she knowingly intended to obstruct the Grand Jury investigation.
Mattingly will remain in custody pending transfer to a U.S. Bureau of Prisons facility.
The FBI and the Tulsa County Sheriff’s Office investigated the case. Assistant U.S. Attorneys Vani Singhal and Timothy Faerber prosecuted the case.
