The label is “Death Angels”
Wings were earned for 9 white men,5 white women or 4 white children. Gus Coreris and John Fotinos in SFPD Homicide did the work that shut down the Death Angels in SF. The SF episode was part of a statewide investigation into organized black on white murders in CA at the time.
“Zebra” by Clark Howard is the better account. When I first became aware of the book I tried to get it at the SF Library. It could not be checked out and the staff went in back and brought the book to you, allowing you only 30 minutes to look through the book. I finally got a copy at a used book store. Apparently the book was “restricted” at the library.
“Zebra” that’s the book I read. Like I said, it’s been a long time.
