TULSA, OKLA. ? The Muskogee County district attorney filed a motion Tuesday to extend the supervision beyond the 18th birthday of teenager who shot and wounded five classmates at a middle school.

Seth Trickey, 17, shot five students at Fort Gibson Middle School with his father’s 9 mm handgun on Dec. 6, 1999. Trickey pleaded guilty to the shootings in 2000 and spent about three years at the Rader Diagnostic & Treatment Center in Sand Springs.

He has been released from Oklahoma Juvenile Affairs custody and has moved in with his maternal grandparents in Lawrence, Kan.

Muskogee Dist. Atty. John David Luton said he believed Trickey should remain under some sort of supervision because of the magnitude of his crime.

Four students were directly hit by Trickey’s gunfire, and one boy was grazed by a bullet that had passed through another person. One of the students was shot in the face.

Trickey is not allowed to leave Douglas County, Kan., without a judge’s approval and cannot return to Fort Gibson at all. He must also continue receiving psychological counseling and reporting to Kansas juvenile officials weekly.

Trickey has been in compliance with all the restrictions, said District Judge Tom Alford.

Trickey will start school this fall in Kansas, and is scheduled to discontinue supervision within the next two months, he said.

The supervision extension will be considered by the court on October 26, with reports of Trickey’s progress from Kansas authorities, Alford said.
