Good ideas bobbisangel.
Here is a straight forward question. The answer will go a long way toward solving this case.
Where is Jennifer?
that is the million dollar question.
I think finding the POI is the key, and he will lead you to JK.
I had a thought:
I wonder if before JK was abducted, if Mosaic had used a private firm, who drive around from one complex to another, throughout the day and night, and respond to calls. You see their cars in traffic, have the lights, and say, security, or such.
It is quite common where I reside. Most places would rather handle the problems internally, than have police reports of disturbances at their complexes.
So, what if, one of these patrol guys, catches notice of JK one day.
He is never stationed at Mosaic, but frequents it, in his rounds.
Through this, he can spy on her, without anyone knowing what he is up to.
Not only that, but, nobody would suspect him, since he wouldn't be in the category of suspects.
So, he notices Jk is gone, or who is to say there weren't complaints that weekend of parties, or noise, and he responded, or heard about it.
Once, I went to a game at our local professional arena. Coming out, LE was directing traffic, and i thought nothing of it. Later on, after this case, I took a good look at the guy, he wasn't a cop, but, a private security guard dressed "exactly" like a cop. Not only that, but, they conceal their waist, so, people can't see that they are rent-a-cops, and don't carry guns, but carry mace or stun guns instead.
Then, on that day, he makes his move. He is doing his rounds, and notices JK walking to her car. He can't take Jk in the work car, since it probably has GPS tracking, and is noticeable, so, instead, he is forced to use JK's.
Once the Kesse's alert Mosaic, they would probably call their security company, and have them come over, and check out the complex. He receives this call, and knows the heat is on, and dumps JK's car, hops the wall, and comes upon the scene.
Of course, this is "hypothetical". We don't know if Mosaic used such a place, or if Mosaic had a guard at the guardhouse that day. But, could it have happened?
It would explain just about everything. Rd's uniform patch, the tracking dogs, why nobody saw anything, why he knew about technology and LE methods, why he knew about the shortcut.
