POTEAU, OK — A 31-year-old Oklahoma man was arrested in Georgia after allegedly shooting his twin sister and her 17-month-old daughter to death at their Poteau home, spending only four minutes inside before fleeing the state.
Grant Wilson faces two counts of first-degree murder in the deaths of Gabrielle Wilson and her toddler daughter, who were found with fatal gunshot wounds Saturday evening. The Oklahoma State Bureau of Investigation tracked Wilson to Georgia, where Monroe County deputies arrested him after a brief chase on Interstate 475. The case has shocked investigators due to the family relationship and the brief timeframe of the alleged murders, captured on surveillance footage that shows Wilson’s vehicle at the residence for approximately four minutes.
LeFlore County Sheriff’s deputies responded to Gabrielle Wilson’s home in Poteau at approximately 4:30 p.m. on Saturday, March 21, and discovered both victims dead from apparent gunshot wounds. Surveillance footage from a neighbor’s camera system showed Grant Wilson arriving at his sister’s residence at 9 a.m. that morning, walking from his car into the home, then exiting about four minutes later and speeding away from the scene. “It’s just something that is hard to fathom when you are talking about a brother to our victim and to know that she had such a young child,” said Hunter McKee, public information manager of the Oklahoma State Bureau of Investigation. “This was a senseless crime.”
According to court documents, investigators determined that Grant Wilson shot Gabrielle Wilson in the face and her 17-month-old daughter in the head. Officers found Gabrielle Wilson dead on her back with shell casings scattered nearby, and blood spatter evidence on both the floor and walls. The toddler was discovered dead in one of the home’s bedrooms. An arrest affidavit detailed how surveillance footage captured Wilson’s gray Honda Accord at the residence for the brief four-minute timeframe. The twins’ father told investigators that Grant Wilson owned the same caliber weapon allegedly used in the slayings and had a history of violent arguments and physical altercations with his sister, though he did not elaborate on the nature of their disputes.
Police issued an alert asking law enforcement agencies to watch for Wilson’s vehicle, and traffic cameras picked up his license plate in Georgia on Sunday, March 22. Monroe County Sheriff’s deputies spotted the Honda Accord traveling south on Interstate 475 near Macon at approximately 12:30 a.m. Sunday morning. When deputies attempted a traffic stop, Wilson fled, leading them on a brief pursuit before surrendering and stopping his vehicle. Deputies found Wilson armed with a pistol when they arrested him, and a subsequent search of his car revealed an arsenal of weapons and supplies suggesting he was prepared for an extended period on the run.
The vehicle search turned up two .40 caliber Glock handguns, a Browning lever-action rifle, a shotgun, several loaded magazines, and various loose ammunition. Deputies also discovered packed bags containing clothing, long-term food supplies, and additional ammunition, indicating Wilson had prepared for an extended flight from authorities. Family members told investigators that the twins had a documented history of violent confrontations, though the specific motive for the murders remains unknown to Oklahoma detectives. Court records show that other relatives were aware of the siblings’ troubled relationship and previous physical altercations, but investigators have not revealed what may have triggered the deadly encounter.
Wilson remains in the Monroe County jail in Georgia awaiting extradition back to Oklahoma to face the murder charges. The Oklahoma State Bureau of Investigation expressed appreciation for assistance from the LeFlore County Sheriff’s Office, District 16 District Attorney’s Office, Oklahoma Highway Patrol, Office of the Chief Medical Examiner, and the Monroe County Sheriff’s Office in the investigation. No attorney has been listed for Wilson in court filings, and he has not entered a plea to the charges. The investigation continues as authorities work to determine the exact motive behind the killings and piece together the events leading up to the Saturday morning murders.
Wilson is currently held without bond pending his extradition to Oklahoma, where he will face formal arraignment on the first-degree murder charges. If convicted, he could face life in prison or the death penalty under Oklahoma law.
