Without regard to Sergio's comment about his beautiful daughter, I have a difficult time believing that the Celis would be able to toss Isabel's body somewhere like trash. As Catholics, I'm sure that they know that human life is to be treated with dignity at all stages, and the body respected in death.
2300 The bodies of the dead must be treated with respect and charity, in faith and hope of the Resurrection. The burial of the dead is a corporal work of mercy; it honors the children of God, who are temples of the Holy Spirit.

If Isabel died in the Celis home due to an accident, I doubt that her parents would have allowed her body to be desecrated by the elements. Rather, I believe that they would have contacted extended family to help them find a place to give Isabel a proper burial, perhaps in Mexico. While it gives me the heebie-jeebies to even think about it, that both parents emphasized Isabel's braids in interviews leaves me wondering if Isabel was dressed beautifully and her hair lovingly braided prior to her removal from the home to be laid to rest. :moo:
