American contract killer Richard Kuklinski would kill with a small mist of a cyanide solution to bare skin. Unless there is a specific test for cyanide, the autopsy would always list the cause of death as heart failure. It can be done in broad daylight, without anyone observing what actually happened ...
As I had posted earlier in today’s Savage thread:
Certainly the first thing that I thought when I heard about Andrew’s death due to “natural causes” was a hit by a wet work specialist. While its not completely out of the ordinary for a guy in his 40s to have a heart attack it seems pretty unlikely in this case.
Like sushiman pointed out - Richard “The Iceman” Kuklinksi used to inject some of his targets with cyanide or put it in their food. It mimics the appearance of a heart attack. Certain foods hide the taste of it very easily. After a few days you can’t find cyanide in a body. That is one reason it is such a good murder weapon. It breaks apart into carbon and nitrogen. The distinctive order of bitter almonds is only noticeable on a fresh body; it is lost as the body decomposes and hardly any medical examiner checks for it. It is a standby of the old KGB and I’ve read plenty of books on mob cleaners using it as well.
Just sayin’...
