First-degree murder charges have been dropped against two men accused of killing a 19-year-old Oklahoma woman whose dismembered body was found in a duffel bag.

Oklahoma County prosecutors filed a motion on Friday to dismiss charges against Jimmy Lee Massey Jr. and Luis Ruiz pending further investigation into the death of Carina Saunders. District Judge Ray Elliott signed the motion that states charges can be refiled in the future pending the outcome of the investigation.

Saunders' dismembered body was found Oct. 13, 2011, behind a grocery store in the Oklahoma City suburb of Bethany. Last month, Bethany police asked the Oklahoma State Bureau of Investigation to take over the case.

Investigators have said Saunders' death involved human trafficking and drugs.
