The bodies showed traces of external physical trauma, reports El País. When questioned by police, their mother mentioned "extra-terrestrials and the possibility of resuscitating the two children."
The mother is now being considered the principal suspect for the death of the two children. During interrogation, the father said that the mother tried to drown the two children following a heated dispute.
The father, a Belgian national, is in custody while authorities try to determine his role in the deaths. At minimum, he is suspected of having hidden the bodies.
El País also reports that the mother came from a rich family and lived an “alternative mode of life", while both she and her partner consumed drugs and suffered from mental health problems.
