Hydrogen cyanide gas - the assasins weapon of choice for causing a heart attack.

In Andrew’s case, if hydrogen cyanide was used, since he already had heart problems it would appear a natural death.

Using a dart, hydrogen cyanide would only leave a small red mark where the dart hit.

Folks, this autopsy is taking a long time for determination, particularly if he died from an infarction (heart attack). Must be waiting for toxicology reports, I suspect.

If he just had a heart attack odds are the autopsy won’t show anything (other than a blocked artery), a recent attack will show soft necrotic tissue, and a healed MI should show scar tissue.

"Using a dart, hydrogen cyanide would only leave a small red mark where the dart hit."

And where is the dart? Did it auto-eject and self-destruct?

It once took me nearly six months to get a toxicology report from the coroner in Orange County, CA...and even then, I didn’t trust it.

Blocked artery,THE WIDOW MAKER, would also be obvious at autopsy.
Toxicology reports are what we are waiting for. Hope there are God fearing people involved.

I have darted cattle...for various reasons. We have to have that dart stick in them awhile...so the med's will pump in.

I'm not a secret agent spy guru...so maybe my Okie knowledge is bunk.

And my understanding of cyanide is pretty much nil.

So I know nothing....
