GUTHRIE, Oklahoma -- Two men wanted in connection with a shooting at Langston University surrendered Saturday to authorities in Logan County.

Chesley Griffin was a suspect in Thursday's shooting. His brother, Neiman Johnson, was wanted as a person of interest. A spokeswoman for the Oklahoma State Bureau of Investigation said they both turned themselves in Saturday afternoon.

Johnson was not arrested but is being interviewed by investigators.

Griffin was booked into jail for assault and battery with a deadly weapon. His bond was set at $50,000.

The OSBI said Griffin was the suspected gunman in a shooting at Langston University. A fight broke out Thursday night when two men confronted a group of students. Investigators said one man pulled out a gun and started shooting.

Twenty-one-year-old Jordan Hunter was treated for a gunshot wound to the leg at an Oklahoma City hospital and released, but another student who was kicked in the head was transported in serious condition to a hospital. His name wasn't released.

Langston University police arrested Michael Vaughn the night of the shooting. Vaughn is the brother of both Griffin and Johnson.
