ALTUS, Okla. (AP) A Fort Sill-based soldier from Texas has been arrested on a first-degree murder complaint in the shooting death of a bar owner near the southwest Oklahoma town of Eldorado.

The Oklahoma State Bureau of Investigation says Pvt. Joshua Dylan Lusk of Quanah, Texas, was arrested in Lawton Thursday night. The 24-year-old is scheduled to be arraigned Friday in Jackson County District Court in the shooting death of 50-year-old Andrew Russell White.

Authorities say a bartender at Dub's Bar arrived for work Monday night to find White dead inside. Jackson County Sheriff Roger Levick says White died of a single gunshot to the head.

OSBI spokeswoman Jessica Brown says investigators still are working to determine a motive in the killing.
