Meanwhile, we have gangsters who 'rat' to the FBI
and die a hideous death at the hands of
other gangsters who hate informers.

The gangster in question here
was put on trial and found guilty in Boston,
and that fairly recently,
getting huge amounts of mass media attention.
Especially regarding an unfortunate young woman
who was amongst his murder victims.

Now the South Boston house
where her remains were first interred in the basement
has been put on the market,
for just under four million dollars.
