On Thursday, the Los Angeles serial killer nicknamed the Grim Sleeper was convicted of 10 murders. However, he may have killed far more than that.
The background story is educational and eye-opening in that the police seemed to make no effort to catch him over a quarter century because the victims were black women, many prostitutes.
In this documentary, a British filmmaker uncovers police apathy and easily discovers who is the Grim Sleeper. Fascinating viewing.
