Island hopper, you are very perceptive. An almost identical incident happend to me about 5 years ago. It wasn't my daughter, but could have been. My career was as a first responder and I had experienced many tragedies with multiple fatalities, but none that affected me like this innocent abduction victim.
I began a very dark journey backtracking & researching the predator/abductor, which turned out to be a prolific serial killer, active for 4 decades, in multiple states, with multiple victim profiles.
This poi scenario resulting in diagnosis, suspicion, etc., is deja vu..
The psychopathic predator responsible for Mickey Schunick's abduction will not be obvious, but stealth, as is a chameleon, imo.
