Well you asked me if it makes sense.
The Culprit kidnapped her, put the note with in the paper at the same time, and left. Now I am not a genius, but it doesnt take a detective to know this. Oi oi, It's kinda obvious too, how she said she isnt gonna tell you wear she is. If she left a note saying she is helping a friend, shell most likely tell you where she might be, or call someone, But she cannot since she is held captive
