A prosecutor in Atlanta says a grand jury has indicted a man accused of killing two 17-year-olds behind a suburban supermarket.

Fulton County District Attorney Paul Howard on Tuesday announced that a grand jury indicted 20-year-old Jeffrey Hazelwood on charges including murder, aggravated assault and aggravated sexual battery.

Lawrence Zimmerman, an attorney for Hazelwood, did not immediately have a comment on the charges.

Prosecutors say Hazelwood killed Carter Davis and Natalie Henderson Aug. 1 in Roswell. A medical examiner's report said Henderson was found naked in a "sexually suggestive position," while Davis was wearing only shorts with his arms outstretched on each side. Both teens were fatally shot in the head.

Howard said the investigation revealed that Hazelwood secretly watched the two teens behind the store before killing them.
