TULSA, Okla. – A Tulsa woman was sentenced today for Second Degree Murder in Indian Country and Discharging a Firearm During and in Relation to a Crime of Violence, announced U.S. Attorney Clint Johnson.

U.S. District Judge John F. Heil, III, sentenced Alexis Danielle Flanner, 26, to 240 months followed by five years of supervised release.

In July 2022, Tulsa Police officers were dispatched for shots fired. Upon arrival, officers found Estrella Mendoza, deceased from a gunshot wound. Officers watched security footage that showed Flanner and Estrella enter the store together. After the pair left the store, Estrella was seen crawling away from Flanner before she collapsed. Flanner was seen fleeing the scene.

A witness stated that he tried to help Estrella. Before going unconscious, Estrella said that Flanner shot her. Officers went to Flanner’s residence, where they found the vehicle she left in that had fresh blood splatter and the firearm used.

Flanner told officers that she was mad at her sister-in-law, Estrella because she would not return her marijuana grinder. 

Flanner is a citizen of the Muscogee (Creek) Nation and will remain in custody pending transfer to the U.S. Bureau of Prisons.

The FBI and Tulsa Police Department investigated the case. Assistant U.S. Attorneys Aaron Jolly and Valeria Luster prosecuted the case.
