I STILL can't get JM out of my head. The fact that there is no mention in the dump just makes me more suspicious, add to the the fact he was obviously a regular in the house that would know the comings and goings of the family and imo had access to come and go as he pleased.
I agree and have a few thoughts (theories) about this that include information gleaned from the recently released LE docs (I have not painstakingly researched all docs as many here have gratefully done). Specifically, many have expressed interest in "maglighting" guy NMc who lives with his gf close to the Celis home. It is also reported by a relative of JM that JM resided with the SC/RC family for approximately 6 months. If NMc is approximately 35, not too big a difference in age exists between JM and NMc. I wonder if while living as neighbors, the two men forged an acquaintance or friendship. Could there be some level of collaboration between the two?
With that said, IMO it's more likely NMc is a well intentioned, possibly, too eager guy who took it upon himself to search tunnels for a missing child. Living in such close proximity to the Celis', it is possible NMc learned of Isabel being missing when her family initially searched for her in the neighborhood.
The use of two vehicles (the Jetta and the other, was it a hatchback?) may be attributed to something as simple as where each car was parked at his home and in which car it was easiest to leave. LE watched him when he returned to the Jetta, possibly returning home. Maybe gf was waiting with breakfast prepared, something they agreed upon when he left their home. Once engaged with LE, he may have remembered he was due home hence, his sudden exit. Also, LE reported the gf was headed to work which could explain NMc needing to return the Jetta to gf. Later, when NMc was noted by LE to be in the other vehicle, he was then in his own car.
JM on the other hand, is glaringly absent from the LE reports. Especially when one considers the detail provided about other family members, their cell phone screen shot photos and the search warrant served on their truck.There has been speculation here that the reported December visit by CPS to the Celis' home might somehow be linked to JM's stay with the Celis family. There are also the rumors of JM's income being associated with illegal activities, his maybe owing money to the "wrong" people and the possibility of consequences exerted against JM for illegal involvement.
I wonder if speculation of a retaliation aspect to Isabel being taken from her home is one in which JM exerts retaliation against SC. The reported "hoax" phone call saying SC borrowed $170K from a physician employer might be a misrepresentation or half-truth put out there by JM to assure criminal acquaintances he could pay his debt. JM might be very angry with this family not coming through for him.
All this is only my opinion.
