New developments in a Tulsa double murder case from this past summer.
Shania Craven has been arrested on a material witness warrant, and possession of marijuana.
We're told prosecutors want Craven to testify against Jeremy Foster and Willie Wise.
They are accused of killing two men at the Best Buy near 41st and Darlington.
Killed were 58-year-old Graydon Brown who was inside the store shopping with his daughter, and 34-year-old Scott Norman.
