HUNT COUNTY, Tex. (KXII) -- 48-year-old Roshawn L Knight of Los Angeles was arrested in a traffic stop earlier this month.
A 5-year-old child riding in the car with her was put in the care of the department of family and protective services.
Knight is in the Hunt county jail awaiting extradition back to California.
Local authorities declined to release details about the murder warrant because it's not a local case.
