How did Rosario find the cameras

The movie jumped around time line wise, so finding the cameras was a flash back.

I agree. Decent movie, but way too much bouncing around.
All of a sudden out of nowhere she suddenly finds the camera!!!

Just watched this today, a free rental from my public library. Agree with several previous posters concerning the sometimes confusing use of flashbacks. The title of this thread is my question. What tipped off Detective Rosario to the presence of the cameras ? That scene was even in the trailer. Was that ever explained ? Did I somehow miss it?

Well, she obviously found the cameras before she got abducted. But the question still remains: how did she find the cameras? Or perhaps it was the mother who first discovered the cameras. But that was not explained in any way.
