Yes, I found only this one as well, mentioned in a later post below.
Fwiw, even with this story, it doesn't sound like they planned to do this from the start. Rather, after forcing the guy to start the car they threw him in in ditch. Later, it sounds like somebody turned the car off (sorry Boss!), and then the thugs went back and cut a fingertip off the guy and brought it back.
No word on whether it worked.
The Diebold exec's statement makes it sound like its a new wave of pre-meditated crime. Maybe there was an incident behind it, but it doesn't seem likely that it's some new fad in crime.
Sure, cut someone's fingers off, like a spy or a Brinks guard, because they would refuse.
But who would refuse ATM access and risk their fingers being cut off? And what criminal would think it's good to have a screaming victim around while they swipe a bloody finger??
So maybe they kill them first and then take their finger. Sure but that's just the same as getting their pin/card and killing them. Except sans the bloody finger.
