I have been able to confirm this through multiple sources.
As of this publication, I have not yet seen this story mentioned anywhere else in the media.
Update: KALB also reported on former Rep. Scott’s passing during the 10 o’clock news.
Update II: So has The Town Talk.
Today, Alexandria lost one of her true native sons and champions, John Wyeth “Jock” Scott II, a dynamic three-term State Representative, President of the Louisiana Bar Foundation, two-time candidate for United States Congress, attorney, accomplished author, and professor of history at LSUA. He passed away this afternoon at his family home in the Alexandria Garden District. He was 61 years old.
Like many, I am shocked and saddened by former Rep. Scott’s passing and offer my deepest condolences to his wonderful family.
Just recently, I purchased Mr. Scott’s latest book, Natalie Scott: A Magnificent Life, a biography of his trail-blazing and barrier-breaking great-aunt, which was reviewed here by the Times-Picayune. Quoting:
When I imagine my ideal dinner party with figures from New Orleans history, writer Natalie Scott (1890-1957) and her friends, writer Lyle Saxon and artist William Spratling, are always near the top of the list. In his long and loving biography, “Natalie Scott: A Magnificent Life, ” John W. Scott has written his great-aunt into vivid life.
Here she is, in all her intrepid glory, and here at last is a fine collection of her writing, especially her wartime letters and journalism, as well as a charming selection of photographs.
Mr. Scott was scheduled to sign copies of his book during next week’s annual Historic Preservation Conference in Alexandria.
Among other things, Mr. Scott’s legacy includes helping to turn LSUA into a 4-year institution, which he worked toward as the Chairman of Friends of LSUA.
On a personal note, I would be remiss not to mention how incredibly gracious, supportive, and kind Mr. Scott and his wife Cyndy have been to me and my family. He was a good man, and as I stated earlier, a real champion of this community.
And like his great-aunt Natalie, Jock Scott lived a magnificent life of accomplishment.

I just saw him earlier this week. Just goes to show…you never know when your number will be called. I worked for one of Jock’s State Rep Campaigns when I was in college and found both he and his wife to be a very affable people. While he did have some political success in his earler years, people never really could get over the fact that he was Nauman’s son.
I am saddened for his family and for the community. Cenla suffered a great loss yesterday. I too spoke with him just last week. I was making the arrangements for his book signing. When things like this happen, it makes me feel very human, you never know when it will be your time to go.
I’m Faez K. Abd, I’m working in Iraq with US Army, I have a shock and very sad, We lost a big heart and very nice man..
I’m sorry Cyndy my deepest condolences, I will never forget Mr. Scott
I’m sure he’s in paradise. GOD BLESS HIM.
Jock was my class leader at Bolton High School. Jock seemed to possess more of the elements of greatness combined with goodness. He set a “positive” example for all fellow students. I am appreciative for the grateful recollections of him during that period, and little surprise that he continued in later life to exhibit the same leadership skills that he showed us at Bolton. His sudden and untimely passing is an irreparable loss to all who knew him.
