This is NOT a Red John Theory, but a theory about the mysterios tupperware container in La Roches safe :)

I think La Roche has a son, born out of wedlock.. or something like that..
He hides the container for NINE years in his safe.. and the cast of episode 5x21 contains a young boy named Micah Nelson (maybe 9 or 10 years old ;)) his part in the episode is named "tupperware boy" ^^
