Okay, maybe one of those witness advocates did it.
However, if it was the intruder then surely he has to be two things: weird and wired!

Weird: bringing a can of pineapple and mucking about in the kitchen in the dead of night solely for some sort of very subtle inside joke.

Wired: He has to know that pineapple meant something special to JonBenet and would be recognized by her family as some sort of macabre joke.
