Case of the Baking Soda Blowout

Baking soda blanketed our master bathroom (the picture does not do it justice).  Aiden first came upon the scene, but he maintains his innocence.  Audra has invoked her right to remain silent.  As I worked to recover evidence, I did come across footprints--the left print of the larger culprit (whom I believe to be the leader), and both the right and left prints of the smaller accomplice.  The investigation continues...

 Aiden (suspiciously wearing baking soda) found the mess, but insists he is not responsible.

Audra stands by as I record the evidence.  Curiously, new prints appeared as she came over to assist!
