The Hillside Strangler: Devil in Disguise – The authors of this documentary project invite viewers to take a different look at the infamous serial killers, cousins Kenneth Bianchi and Angelo Buono. Their names made headlines in the United States in the early seventies. For a long time, the criminals posed as law enforcement officers, gaining the trust of their victims and luring them to their certain death. The bodies of these people were discovered on the hillsides in the eastern part of Los Angeles.
