On March 21, 2026, deputies answered a call for a cardiac arrest at a home on Old Tarby Road in Poteau, Oklahoma, and instead discovered that 31-year-old Gabrielle Wilson and her 17-month-old daughter had both been fatally shot. Investigators quickly focused on Gabrielle’s twin brother, Grant Wilson, after learning of a history of violent arguments and physical altercations between the siblings and collecting scene evidence pointing to him.

Neighbor surveillance footage reportedly shows a vehicle matching Grant Wilson’s arriving at the residence and leaving four minutes later on the day of the killings. The next day his vehicle was spotted near Atlanta, and he was taken into custody after a brief pursuit; weapons, spare clothes, and long-term food supplies were found in the car. Extradition to LeFlore County is expected and two counts of first-degree murder are anticipated.

The motive has not been made public. If anyone knew Gabrielle or her family, or has information about that day or the vehicle movements, please share what is known with investigators.
