A buddy of mine had an uncle that was in debt (gambling) up to their eyeballs. Had some suited guy come to their house/door frequently pushing for info on where that uncle was. Buddy claimed his father had a few conversations with the guy (so I am even getting it hearsay) trying to figure out what his brother (the uncle) had done & finally pulled a gun when he opened the door for the last meeting told the guy that his brother was not there & was not welcome again after he found out more details. He was never bothered again. He ended up asking this collector at one point how much a human life was worth, the guy told him a nameless person was a few thousand.

No idea how accurate the story is, though that $15k each makes for lots of non public interest bodies.
