I recently  checked  this  book out  from  my local  library:

This  boy’s  grave  is  in  Ypsilanti, MI’s Highland Cemetery  and  only received a headstone  two years ago following a Go Fund Me campaign. From 1935 until 2016, this 7-year-old’s grave was sadly unmarked. He was stabbbed 14 times, and no one  was ever convicted  of his murder. I believe  that in a case of “overkill” like  this, the killer must have known Richie (the victim). But what  do I know? I’ve  just  watched  a lot  of  crime shows!
