Indiana authorities hope slain girl's audio recording will lead to her killer
"This young lady is a hero, there’s no doubt,” said Indiana State Police Sgt. Tony Slocum. “To have enough presence of mind to activate that video system on her cellphone, to record what we believe is criminal behavior that’s about to occur.”
If BG immediately engaged the girls at the end of the bridge and this was captured on the recording, as in Libby took the video and then stuck the phone in her clothing, still recording, than I don't think Slocum would have said "what we believe..." IMO, that indicates there is a gap (however long or short) between the visual of him, and the following:
Delphi: Officials say Internet rumors can hurt investigation
She also captured a man’s voice saying, “down the hill” during what police call “criminal activity.”
This indicates to me that the girls, at this point, were NOT with BG voluntarily. They weren't showing, or following him on an alternate route, or going to see something with him, etc, when he said, "down the hill." This is JMO, of course. And the reason I question the location of "down the hill," and don't think it is at the south end of the bridge, is because of what I said in the first paragraph about the possible gap between video and audio. Maybe the criminal behavior about to occur is:
Stalking
The term “stalking” means engaging in a course of conduct directed at a specific person that would cause a reasonable person to fear for his or her safety or the safety of others or suffer substantial emotional distress.
This is the part that I'm not sure about, and
if it occurred, it could have been on the bridge (maybe he even tried to converse with them the entire walk back across- thus no calling for help), or he just sort of hung close by - unnerving, but non-threatening, or he went back first and blocked their path, or he watched them from the bridge, whatever. However it happened, if he was acting strangely towards them, and/or made them feel he had intentions to engage them, IMO, that would be considered stalking, and criminal behavior.
And this may have already been posted during the Amber Alert discussion, but again, this indicates, to me, that the girls were killed quickly, and without having been transported anywhere, or moved. JMO
ISP: Delphi Amber Alert wouldn't have helped
"Even if we would've put an Amber Alert out, it would not have done this case any good," Riley said. "In the short period of time, and the location that the bodies were found, it would not have helped us in finding any leads at all."
