Sadly, re: the ATV and the scrapbook, it seems opportunities were missed. I will be the first to say: the investigation does not appear thorough.
More Questions:
Did Investigators get the phone records and the details (content of texts, DMs, voicemails, photos, etc) from Verizon. If not, why didn't they?
Did investigators check the tape and photographs in the scrapbook for fingerprints? If not, why not. If so, were there just too many prints and it would have muddied the waters? Was there something there that was unexplainable and the Prosecution would loose points on cross?
Why didn't they get an overall search warrant, on the initial search, to cover anything related to the disappearance of AM?
What did they find in his camo SUV?
Was it cleaned so thoroughly that it would do nothing to prove the prosecution's case?
Why hasn't the prosecution said whether any fingerprints were found anywhere? No fingerprints would underscore a massive cleanup. With the fight/struggle between AM and RAT, IMO proven by the prosecution, there should have been fingerprints. Why is this not being addressed?
"Thorough," is not a word that is coming to mind.
