See if you can locate Kenny Eto, formerly of Chicago.  I believe he is currently in the witness protection program.  In '83, his colleagues decided to retire Ken, with three rounds from a .22 to the back of his head.   None of the rounds penetrated.  Ken than began to sing a long and beautiful song.
If I remember correctly, the shooters ended their careers in the back of a trunk.
