Some things I'd like to talk about:

Don't exclude the possibility that Red John doesn't belong to the list of suspects.

Suppose you are Bruno Heller.You came up with an excellent plot idea.
In this plot idea you put the list of suspects, and Red John is off the list.Then in an interview, they ask you:"Is that list includes Red John?'
When you answer "Yes" you are considered as a liar.
When you answer "No" you give out a HUGE spoiler
When you try to avoid the question people will start to be suspicious
When you answer "Maybe' it's like you are saying 'He is not"

So Heller picked the most clever answer to give in this question."You can trust that list' it's like he doesn't say directly "He is on the list but at the same time it is questionable.Think about it.

Some clue on Lorelei Martins I found:
