Chilling 911 Tape Bared in Bid for Clues to Girls' Murder

Authorities struggling to crack the case of two Oklahoma girls found murdered last month have released an emotional tape of a 911 call made by a family member who discovered the bodies, reports CNN. Investigators hope the heart-rending tape will spur somebody to identify the killer or killers who left the girls, ages 11 and 13, dead in a ditch with multiple gunshot wounds.

"They are both down here dead—my granddaughter and her friend," the woman says on the tape. "Lord help me, please. Oh God, oh God, my babies!" Police have followed more than 500 leads, but have yet to uncover any suspect or a motive. Two guns were used to kill the girls, leading investigators to believe there were two shooters.
