Police in Powder Springs have arrested a third suspect in a double homicide which left a three-year-old girl without her parents.

Raymond Ladell Webb, 41, was arrested on Aug. 30 and charged with concealing the death of another, hindering apprehension of a criminal, and drug charges, Cobb County jail records show. A police warrant obtained by WSB-TV claims that Webb was responsible for setting up a drug deal which led to the deaths of Anthony and Catherine Costner on Aug. 6.
