Find April Jones!

If the Police have the Main Suspect why won't he tell them where she is?

They could 

1. offer to set him free, tell everyone when and where (lynch mob gathers)
2. give him truth serum and get him to tell them. He's going to jail for a long time anyway.

Why not - bugger his human rights finding April is more important. Mark Bridger can rot in hell. How could he do it to a little girl.Why won't he tell them?

I really don't understand. In this case a judge should ORDER him to tell or have truth serum.

After all her life is at stake if its not too late.
