A man accused of stabbing another inmate in a Lawton correctional facility in 2012 is facing trial.
Ryan Garcia is accused in the death of Sonny Limpy, 25.
It was the second murder in the prison that year.
Limpy was in prison for the 2005 murder of an Oklahoma county man.
Prison officials say Limpy was stabbed several times in a fight with other inmates.
Five inmates were under investigation in the killing.
Testimony indicates Limpy was killed because he resisted efforts by other inmates to organize gang control.
