After years of delay and a cross-country manhunt, a federal jury has convicted a Pryor husband and wife of sexually abusing a minor in Indian country, delivering prosecutors a long-sought win in a case that first surfaced in 2019. Gretchen and Larry Tennison were found guilty Monday after days of testimony and evidence. They have not yet been sentenced.
How the case unfolded
The allegations date back to 2019, when a teenager told a family member that she had been groomed, given alcohol, and sexually abused. Investigators served a search warrant at the Tennisons’ Pryor home in September 2020, and a federal grand jury returned an indictment under seal in May 2021.
After the couple left the area, the FBI sought public help to track them down. The pair were ultimately arrested in Columbus, Montana, in December 2025 after a tip, according to an FBI wanted poster hosted by KOAM.
Evidence at trial
At trial, prosecutors told jurors the couple groomed the girl with grape and apple flavored alcoholic drinks before sexually abusing her. A Mayes County deputy testified that officers recovered sex toys and a jar filled with purple and green beer bottle caps that matched the victim’s description.
Prosecutors also said the Tennisons used the aliases “Fran” and “Keith Smith” while they were on the run, and noted that Gretchen Tennison is a member of the Cherokee Nation while the victim is also a tribal citizen. Those details are described in reporting by FOX23.
Why this was a federal case
Because the crimes involved a tribal citizen and occurred in Indian country, federal authorities took the lead. Federal law gives the United States jurisdiction over certain violent offenses on tribal lands, including sexual abuse of a minor.
The U.S. Code provides that offenses committed in Indian country may be tried in federal court under 18 U.S.C. § 1153, and it treats sexual abuse of a minor under Chapter 109A, including 18 U.S.C. § 2243, as a federal crime with severe penalties. The statutory texts spell out how jurisdiction and penalties attach and how sentencing can result in lengthy prison terms.
What comes next
The Tennisons have not yet been sentenced. Court filings and news reports indicate that a sentencing date will be set once presentence reports are prepared. Prosecutors have publicly thanked the federal and local partners who helped locate and arrest the pair, and pretrial records show the couple sold belongings and moved to Montana while authorities were trying to find them. FOX23 reports that formal sentencing will occur at a later hearing.
Authorities credited a public tip, along with coordination between the FBI, the U.S. Marshals Service and the Stillwater County Sheriff’s Office, for the 2025 capture in Columbus, Montana, which finally allowed prosecutors to bring the case to trial. Earlier coverage of the arrest and the couple’s fugitive status is available from local outlets, including reporting by KOCO.
