Sejaryee Lee Bear, a 42-year-old resident of Okemah, was sentenced on Apr. 23 to time served in prison—totaling 147 days—for one count of Accessory After the Fact—Murder in Indian Country, followed by two years of supervised release. The United States Attorney’s Office for the Eastern District of Oklahoma announced the sentence.
The case is significant because it involves a crime committed within the Muscogee (Creek) Nation Reservation, an area under federal jurisdiction and within Indian country. Federal authorities said Bear assisted Michael Wayne Lambert after he shot and killed a victim at an Okemah apartment complex on June 30, 2024. Investigators reported that Bear turned off location services on her phone, deleted data and messages, and accompanied Lambert as he disposed of the murder weapon at Bearden River Bridge.
Lambert was convicted by a federal jury on September 11, 2025. He received a life sentence for Murder in Indian Country and an additional ten years for Discharge of a Firearm During and in Relation to a Crime of Violence earlier this month.
The Honorable Ronald A. White presided over Bear’s sentencing hearing in U.S. District Court for the Eastern District of Oklahoma. Assistant U.S. Attorneys Lewis M. Reagan and Ryan Conway prosecuted the case.
The U.S. Attorney for the Eastern District of Oklahoma leads federal criminal investigations and prosecutions across twenty-six counties—including Adair, Atoka, Bryan—and manages civil actions for the United States while collecting federal debts according to its official website. It also advances community wellness through trust responsibilities to sovereign Tribal Nations according to its official website.
As noted by its official website, this office represents the only federal judicial district fully located within Indian country with operational facilities based in Muskogee.
