Two Red John suspects have so far died in the current season of The Mentalist. One died before the viewers's eyes, and in the hands of another Red suspect. RIP, Bob Kirkland of Homeland Security. The other is presumed dead, and his "last" words were, "Tiger, Tiger." RIP (?) Brett Partridge of CBI Forensics.

The Mentalist Season 6, Episode 4: Aunjanue Ellis returns as Madeleine Hightower

Aunjanue Ellis returns as Madeleine Hightower in The Mentalist Season 6, Episode 4. She reveals to Patrick Jane that FBI thinks he himself is Red John. (Fans in forum sites agree Bruno Heller is listening to them.) This tells Jane that Kirkland and his men broke into his attic quarters.

"Red Listed" explains why Bob Kirkland, also known as the man in the limo in the 100th episode of the series, has made Red John a Homeland case. It further explains why he has asked a suspected Red John suspect if he had seen him before. He's not the big bad Red. He wants revenge against the smiley-painting supervillain.

Could evil Reede Smith be Red John? It is believed Gale Bertram and Sheriff McAllister are with him in a secret organization called, "Tiger, Tiger." But it now appears as if none of these three is the real big bad Red. Instead, they are likely to be the next villains after Red John is caught.

Red John Suspects: Shorter Shortlist with 2 to 5 Names Left

Here's the breakdown of the 7 Red John suspects: two down, three in a secret 'Tiger' organization, two from a cult. Many fans are not convinced Brett Partridge is really dead. But the show is saying that for now.

In the next The Mentalist episode, Patrick Jane will work in another CBI case involving a Visualize member. Red John kills another victim! (Scroll down for the sneak preview video.)

It's time for two suspects from the cult: Bret Stiles and Ray Haffner. The former leads the cult, the other is a faithful member. If it's not Brett Partridge, Red John has to be one of these two men, says "the mentalistas" in forum sites.
