Update (April 15, 4:00 PM): Someone sent me a message saying that the two kids aren't missing. According to her, they are safe and that they are under the custody of a relative from the kids' mother side. She added that a child abuse case has been previously filed against the father. The mother of the kids is abroad. In light of this development which I sincerely believe, I deleted the original article I wrote as well as removed the photos. This page will remain for reference purposes as a lot of people are still asking for updates.
To state the obvious, this wasn't a case of children going missing. It's a case of a family having problems. The case is now in the hands of the family, the DSWD, and other parties concerned. I hope they all come to a good resolution for the issues bugging them. [End of update.]
