This is an ongoing controversy, but I am beginning to see it like this: this uncle may be the spouse of the biologically related aunt-- who would be the sister of Becky or Sergio. That would also explain his surname being different than everyone else's. So, I must ask:
was there an aunt in the home, also? Because I think JM was there overnight, given how immediately he was seen outside the home on Saturday morning.
Speaking of homes, home prices, and newer construction-- it seems this home was purchased during the height of the real estate bubble. This begs the question: has the Celis' mortgage ballooned into an obligation they're having trouble meeting? (like so many in the country these days) If so, the presence of the uncle may indicate they've begun sharing their home with family due to financial pressures. Though both Celis parents seem well employed, I have to state that Sergio's activity with an Opera troupe indicates to me he may only have part-time work as a hygienist... theater auditions, rehearsals, and production schedules are extremely demanding where time is concerned.

This also brings up this sorry motive: is there a life insurance policy on Isabel?
