Series 2 - The Serial Killing Saviour

To view this page ensure that Adobe Flash Player version 10.1.0 or greater is installed.

At school, Herbert William Mullin's classmates voted him 'most likely to succeed'. By the time he was 25, he had taken the lives of 13 men, women and children and spread panic throughout the coastal community of Santa Cruz.

Mullin would claim to be on an extraordinary mission to save lives through murder. Was this heinous serial killer driven by nature or nurture? We follow in the footsteps of the investigators and experts that had to unravel the mystery and ask them – and, in a unique interview, the murderer himself – was Herbert William Mullin born to kill?

    As always too many adverts that cannot be by passed, and programs that keep freezing or not playing at all! Hopeless!

    Once again, the influence of that invisible non-existant entity in the sky is behind these brutal killings. The sooner we ban god the better!

    I too can't seem to get any programmes to play on here :( I have only been watching 5 on demand for a few days but already had 2 programmes stop 10 minutes(ish) before the end and unable to get most to play at all :( Is there a fault with your transmitter channel 5?

    Fascinating documentary on a serial killer that is not very well known. Interesting exploration of his mental condition and delusional belief systems and how they may have contributed to the killings of so many innocent individuals. May the victims rest in peace.
