You should treat these people very nive at first and then start playing with their mind a bit. That way you can start getting answers from them. After a while start asking them questions they might not answer at first but after they get really crazy they will answer some questions.

Also, they can also get hurt mentally and that could mess them up when they have to answer some questions.
