Two devastating murders. That's the opinion of forensic psychologist, Professor James Ogloff, who assessed them both. His introduction to Jill Meagher's killer, Adrian Bayley, came first, in 2012. Inside a sparsely furnished interview room at the Melbourne Assessment Prison, the two men sat facing each other on plastic chairs. Â Bayley, a serial sex offender in his 40s, red-faced and rodent-like, with spiky blonde tips. Professor Ogloff, distinguished in slim black spectacles, approachable and fatherly in manner - a well-liked industry leader with more than 30 years' experience assessing violent offenders. "He really was almost somebody who had two sides to him," Professor Ogloff, who interviewed Bayley over several hours to prepare a psychological assessment report for his sentencing hearing, tells the Twisted Minds podcast.
