Serial killer who slaughtered six people was 'hooked on bodybuilding pills'

California, USA: The British serial killer who slaughtered six people in a bloody rampage had become hooked on a bodybuilding supplement, a close friend has claimed.

Chris Akin, who knew 'virgin killer' Elliot Rodger for several years after meeting him on holiday, said he noticed a sinister change in him over the past four months after he started to take creatine to build up his muscles.
