Not necessarily. It all depends on when the recording stopped. Sadly, it might have stopped when the call came. My own opinion, I don’t quite subscribe to the official version of the death, but I think that maybe Libby, the stronger one, was killed first as most of the anger was towards her. I don’t quite understand the sequence of events, but that the girls could be lured into a car under the simplest pretext and taken away from the bridge is also possible. MOO.
Remembering Jake Patterson. If he could drive a car with JC past the police and none the wiser, something could have always happened here. If the police did not suspect foul play at that time, the girls could have been brought to the creek virtually under the cops’ noses. Not criticizing the police, no one thought abduction and murder on Feb 13, it seems.
