This morning I received an email notification from Mark Giolli, the son of Professor Roland Giolli, informing me that his father passed away some five months ago.
Sad news.
Here is Mark’s original email to me:
Steve, I am writing to ask if you remember my Father Roland Giolli? He was very interested in your books. He died in June. I wanted to say how much he talked of your books in regards to the Black Dahlia and admired your work. Take care.
Mark Giolli
My response to Mark:
Hi Mark:
Of course, I remember your father.  Though we never met in person, I have always considered him a friend and was very appreciative of his ongoing support and important contribution to my ongoing investigation “early on.”
As I’m sure you know, your father contacted and provided me with the details of the important conversation that his father (your grandfather) had with former LAPD Chief William H. Parker as documented in Black Dahlia Avenger under the section, “A Doctor Did It” on pages  468-469.
My sincere condolences to you and the rest of your family at the passing of your father, Roland. May he Rest in Peace.  I could tell immediately that he was a good and honest man who was dedicated to serving others.
If you would like to send me a photograph of him I would be happy to publicly thank and mention his contribution in my website/blog page. ( And, if a short bio is available, I could include that too.
Or, if you prefer he remain anonymous as “Dr. G” I will honor that too.
My Very Best,
Steve Hodel
Los Angeles, California
And Mark’s response back:
While I never actually met Professor Giolli in person, we communicated over the past fifteen years after he originally contacted me in 2004 and provided important confirmation that LAPD Chief William H. Parker had identified the Elizabeth Short “Black Dahlia” killer and that “he was a doctor.”  (See below original information told to him by his father, who was Chief Parker’s personal physician.)
