Jerry Doyle's Cause Of Death

I kept on waiting for the local Las Vegas newspapers to reveal the cause of radio talk show host, Jerry Doyle.
So, I found this from The Wrap:
Jerry Doyle, the “Babylon 5” actor and founder of the news platform EpicTimes, died as the result of chronic alcoholism, Clark County, Nevada, coroner ​​John Fudenberg told TheWrap on Wednesday.
Doyle, who died at age 60 on July 27, died from complications from chronic alcoholism. His manner of death was deemed natural.
The actor, whose credits also included “Moonlighting,” NYPD Blue,” “JAG” and “Beverly Hills, 90210,” was found unresponsive in his Las Vegas home on July 27.  http://www.thewrap.com/jerry-doyle-babylon-5-star-died-of-chronic-alcoholism-coroner-says/
But I am pretty sure that the other vice Doyle had, cigarettes, didn't help matters much.  Another factor probably was his beloved mom passing earlier in 2016.
One thing I know for sure is that he is looking down on us and both laughing and scratching his head about this year's elections.
