McCURTAIN COUNTY, Oklahoma - Oklahoma's Attorney General has filed a first-degree murder charge against a Colorado state prison inmate in connection with a 1984 shooting in southeast Oklahoma.

AG Mike Hunter said in a news release that 65-year-old Ernest Lewis is now charged in the death of Johnny Smith at K.C.S. Lumber Company in Idabel.

Hunter spokesman Alex Gerszewski said DNA testing recently linked blood found on Lewis' boot to Smith.

Lewis and Smith both worked at the company and Lewis was charged with murder in the case in 1985, but Hunter says the charge was dismissed due to a lack of evidence.
