The Mentalist Keith O'Brien episode Dedication

In the fourth season episode of The Mentalist, ep No. 22, titled “So Long, and Thanks for All the Red Snapper,” it closes out with a dedication splash screen saying “In Loving Memory or Keith O’Brien.

Keith O’Brien was a driver that worked with the production of The Mentalist. He had lost a battle with cancer, and the show paid tribute to him with the closing homage, to one of their own. I saw reference to the tribute, but I dug until I found a source of info on his passing.

Ashley Gable, a writer who contributed to 12 episodes of The Mentalist, had replied to some online inquiries about the dedication and had this to say about Keith:

“Keith was a Teamster (driver) on the show. A man with a beautiful voice & an even better smile, he died of cancer during 422 prep.”


She further added:

“we thought an episode about sad goodbyes would be the perfect one to dedicate to Keith. He will be missed. Lovely man. “



No one should ever have to suffer through such an ugly experience as cancer. Ever. I don’t care who you are. (I have some contribution links in the sidebar of my site, because like I say, all it takes is $1. For example, if 5 million people watched a fund raiser telethon in the battle against cancer, and everyone who watched only contributed $1, well, as you can see, this is why it would add up.)

Our thoughts go out to Mr. O’Brien’s friends and family.

My wife Linda and I just finished ep 22 and we’re interested in the comment at the end of the show. We just returned from Phoenix were we said goodbye to a old beloved friend to cancer. It isn’t easy saying goodbye to people you love.

Kind of late, but just saw this episode, with the caption at the end, so like others above, looked into it.
From a fan of your show and with much respect to your crew/family, many condolences.

Michael, I’m so sorry for your loss. Just like Peter Daniel, I had to just search after watching that episode and I can see Keith had a positive impact on everyone he came across.
He is in a better place now.. All the very best. Love from Nigeria.

Dear Michael, we are right now watching The Mentalist season 4 and, reading the dedication of s422 to Keith, searched for background information. We are very sorry for your loss. As an oncologist, I can make an educated guess of what your family experienced. We are glad that your brother in law left such a positive memory!
All the best and thank you for sharing.

Keith O’Brien Sr. was my brother in law. I knew him my entire life and also worked with him, and for him on many television shows and films. I was looking at the title “Driver” and while it certainly was his working title on this particular show, the word just doesn’t even begin to encompass the man’s experience, talents, and intelligence. In the film industry, he was also one of the most efficient, effective and conscientious Transportation Captain’s this industry has ever seen. I traveled and worked with Keith all over the U.S. and I can say without equivocation that he was the best. Outside of work he was always a very popular guy, but he always had a humility about that. He had a fantastic singing voice, and his life could easily have been very different if he had pursued that in his early years, but Keith was always a hard worker; A hands-on, up before dawn, self-motivator, who never tried to avoid a back-breaking task.
I learned a lot from Keith, and will always miss him.
