Via drudge:

  A man was ordered to be held without bail after police tied him to a recent armed robbery. But at least he has his thumb back.
  Police said Bryan Perez, 22, and an accomplice made off with hundreds of dollars in cash in an Oct. 11 raid at an alleged brothel in Washington's Columbia Heights neighborhood. According to charging documents, one of the victims took control of Perez's silver machete during a struggle and hacked off his right thumb.

I guess it was a four finger discount.
