Ouch, that seems like terrible news. Kidnap for ransom makes sense, but why kill the guy anyway/not waiting enough for the money? I mean, obviously 1 million dollars is better than a dead body... I guess things must've gove messed up a lot if that happened. I don't think this was the outcome the kidnappers wanted. If the money was indeed payed in bitcoin, it will only lead to some wallet and while that won't be very useful for identifying the killers, if any other transactions in and out of that wallet happen, it would certainly be something to keep an eye on. It's really sad that such things involving cryptos happen, it gives people more reasons not to adopt them.
