Man, you make good sense....but I just think that with the time elapsed and drones and scent dogs immediately involved, she would have been found already imo.To close off such an important route without at least a 1-way lane passage, and also no media...
have they found her body and have to bring it up the mountain? Just speculation.
I mean, seriously it's not a cellphone or necklace...
a frenzied kill, crime of opportunity, bike and body hidden hurriedly, then a quick escape - those dogs are like friggin magic, idk
