LE was in the Peru home and took every one of KAK's devices...except the iPhone5. In their interview on Feb. 25, 2017, at the house, LE reported that KAK told them his primary phone was the iPhone5, then it says he called days later to tell them he had found it. Clearly, he must have told LE he didn't know where it was, and LE never spotted it during their search, which was obviously for digital devices, since they took them all.
While KAK was away at his polygraph, and TK was at home, the phone shows up on "top of the microwave." Nothing was tampered with during the time KAK was away, seemingly. So how did it get missed, and how did it get found? Where was it during the search, and did it reappear while KAK was away? I mean, it could potentially indicate that TK was in possession of it just before the search, but didn't want that known. But at the very least, he maybe located it while his son was away, but how? It apparently wasn't where LE could find it.
I do NOT believe someone else outside the home was in possession of the phone, however, because if TK contacted someone else to bring it back, there would be a phone or digital trail of that communication (unless that was deleted, as well), not to mention someone swinging by the house to return it. Plus they had just gotten home from Vegas. IMO, that phone was in the house. I'd love to know if there was any activity on it immediately before LE showed up with the search warrant.
KAK reports that when he got home, he told his dad he had been questioned about the Delphi girls. Then, suddenly, he's deleting stuff. A_shots stuff. All of it. Then his dad lies on FB saying KAK hadn't been at home for a long time...
It all stinks.
