A helmet, although I don’t remember whose, was thrown onto the switch causing the speakers to turn on. It was either Mona’s or Hanna’s helmet. Whichever girl was not wearing a helmet at that time, is your answer. In the article above it states that it was Mona’s. Unfortunately, Kate & her other friends had heard every little detail that Hanna had to say about her soon-to-be step-sister.
