Well we know the color of a heart attack victim is most often ashen or blueish....what in the heck happened that night?

There are a lot of excellent theories on this thread. Most tend to support the idea that Breitbart had a lethal dose of something covertly administered to him.

The fact that no game-changing video appeared right after his death, lends credence to the idea that someone got control of the incriminating evidence, then dispatched the messenger.

a not unreasonable thought at all
