Carina Saunders was 19 when her dismembered body was found in a duffel bag behind a Bethany grocery store on October 13, 2011. Her remains were wrapped in plastic, and investigators say she was last seen five days earlier getting into a red pickup truck outside the Newcastle Casino.

The case investigation uncovered links to drugs and prostitution, and investigators encountered claims that a video recorded her torture and murder and was used to intimidate others. In July 2012 Luis Ruiz and Jimmy Massey were charged with first-degree murder after witness accounts; one witness said they saw a video on Ruiz’s phone and another said Massey confessed to witnessing the dismemberment. Prosecutors later dropped the charges, citing a flawed investigation and insufficient evidence.

The Oklahoma State Bureau of Investigation has taken over the inquiry and other persons of interest have been examined, but no one has been definitively charged with or convicted of the killing. If anyone knew Carina or saw her around October 8, 2011, information could still help the investigation?
