The Delphi girls' bodies were found Feb. 14 in a wooded area near the city about 60 miles northwest of Indianapolis, a day after they vanished while hiking.
Carroll County Sheriff Tobe Leazenby says investigators remain confident they'll eventually make an arrest.
Authorities have released two grainy photographs of a man and audio of a male saying "down the hill." That evidence came from German's cellphone.
