Escape the room game murder mystery please help!!?

We bought this today, we flew throught all the other games, this is the last one and we are so beyond stumped, even our math guru is sitting here rocking back and forth in a little corner crying. Part 1 was easy. Part 2? No clue. Can anyone start us on the right path?
