kidnappers Boss?? and many other ?'s

What was the deal with him? Why was did annoying detective ask why he kept the posters? Was he the leader? Only thinking that because he said something about him taking care of the kidnapper when he was 15....very frustrating movie....and how did they find rosario? And what was the deal with the convo about workers not being friends? And who did the boyfriend/annoying cop think the dad reminded him of???? What was that all about? Ugh ugh ugh!!! And kidnapper man left door open when he would go into room....8 years and she couldn't hit him over head with something...he didn't look tough...and was not brainwashed...soooo...ugh....I would've even used the computer to do it...then run out door and shut it....after all this typing I think I hate this movie even more!!! Booo!!
