I am really worried about this Boy, what should I do?

Okay well I have not seen him in nearly a year, and his parents seem to never say anything about him or anything, it is as if he never existed.Also, his sister acts as she does not know who he even is.Its Weird, bit I have not heard anything about him on the news or anything.And in all honesty, I am not even sure if he is still alive. I haven't seen him since mid-last October. If he is still alive, he would be 14 or 15 years old.Also, when I went to his house I did not find any sign of Him, in fact, it was as if he never even lived there.How can I know for sure he is ok?
