(ABC NEWS)Â Police investigating the slayings of two girls in Indiana released evidence today in hopes it will lead to the killer's capture.
The evidence was a video clip retrieved from the cellphone of one of the victims. When police played some audio from the clip at a news conference in the town of Delphi this morning, reporters heard just three words from a deep voice: "Down the hill."

The audio quality is not great, but police said it's enough for someone to recognize the person's voice. Investigators believe the clip was recorded as criminal behavior was about to occur.
"Libby had the presence of mind to turn on her video camera," Indiana State Police spokesman Capt. David Bursten told reporters, referring to one of the girls, Liberty "Libby" German. "There's no doubt in our minds that that young lady is a hero."
