There's more at: Zebra Killings
Here's a sample: MOST SERIAL KILLINGS in America take on a life of their own through movies, books and documentaries. The crimes of Charles Manson, Jeffrey Dahmer and The Son of Sam are still well remembered years after they were committed. Yet there is one set of serial killings that has been almost completely forgotten and is rarely mentioned in popular culture.
The Zebra Killings occurred in the San Francisco bay area between 1972 and 1974 and left 71 people dead. They were dubbed the Zebra Killings because of the radio channel used by the police investigating the case (channel Z). The name would take on a more sinister meaning as it became apparent that a group of blacks was systematically stalking and killing whites simply because of the color of their skin.
Zebra (1979) was written by crime writer Clark Howard and remains the definitive book on the murders. Using court records, police reports, witnesses and interviews with the killers themselves, Howard was able to piece together the horrid details of the murders and the unrelenting hatred that inspired the killers.
The majority of the attacks were carried out by five members of a group within Louis Farrakhan’s Nation of Islam called the "Death Angels." Jesse Lee Cooks, J.C. Simon, Larry Green, Manuel Moore and Anthony Harris were part of this group which believed that whites were created 3,000 years ago by a black mad scientist named Yacub who wanted a race of inferiors to rule over. Death Angels believed they could earn "points" towards going to heaven when they died if they killed whites. For them, whites were not human beings but "grafted snakes," "blue-eyed devils" and "white motherf-----s."
