Stephens County District Attorney Jason Hicks says 16-year-old Michael Anthony Ray has been found competent to stand trial.
In late July, his attorneys filed an application for a mental competency exam for the defendant.
Ray is charged with first degree murder with deliberate intent for the murder of 14-year-old Alyssa Wiles in June.
It happened in the 2000 block of West Walnut in Duncan.
Police say Wiles' father found her body in a pool of blood when he returned home from work.
They say Ray then confessed to stabbing her to death.
He's being held without bond.
