I used to live a couple blocks down Sunset Blvd. from this restaurant, and was a frequent guest there.....Spooky.
Could indeed have been cynide.
From the article:
The very top photo shows where Breitbart died on his back with his head close to the lamp post on the left and his feet under the newspaper vending machine to the right.
Lasseter described Breitbarts skin color as bright red.

I had been under the impression that a cyanide poisoning was not quick, but somewhat slow and agonizing. This sounds like he was dead before hitting the ground. Especially since the guy said he didn’t notice him in any distress; he just fell over. Maybe some of the medically trained on here can tell us what happens with a sudden aortic dissection.
