It strikes me as a variant of the "assault rifles stuffed with heroin" ploy floated in the media a year or so back to describe how BTC is used.
We live in interesting times.
What?! Assault rifles with heroin? Why do I suspect that a few people would actually look forward to something like this?
I remember reading about a "heart attack gun" that uses toxin from (I think) a certain type of jellyfish to instantly induce a heart attack. I believe it's been around since the 60's or 70's. Yes, I'm aware that was tangential
Staying on topic, we likely won't ever see the end of these types of stories unless BTC becomes commonplace, especially those that suggest BTC catalyzes this type of criminal activity in a way other currencies can't (even though they can).
