KENEFIC, OK - The Oklahoma State Bureau of Investigation said they are still not sure what caused a Johnston County teen to fatally shoot a 24-year-old man Friday night.

Authorities said Sergei Hyde was shot numerous times inside a Kenefic home off Perry Drive. He was pronounced dead at the scene.

18-year-old Shelby Hicks was arrested on a first degree murder charge in Hyde's death.

OSBI spokesperson Jessica Brown said Hicks and Hyde are both from the Kenefic area but neither lived in the home where the shooting took place. Brown said the two men know each other.

Hicks is expected in court sometime this week. It is not clear if he has a lawyer.
