The men are wanted in an elderly man’s shooting death outside a convenience store in Boise City. Charles Nieman, of Alva, Okla. was shot and killed as he got out of his truck in the parking lot of a Loaf’n Jug June 12. His wife, a passenger in the truck, was not hurt.

The other man is also Hispanic, approximately 30 years old, and stands between 5′ 6" and 5′ 8" tall.
