The small time drug dealer lived chillingly close to where he committed the grim murder of an elderly woman in 2005 - and recorded it.
"This is not just rape. This is one of the most brutal ways of rape, which are possible," Mr Hoffman said.
According to police files, he beat her with a metal rod and it was only last year that DNA evidence led to Brueckner's conviction for horrible rape.
Mr Hoffman, who has also studied Brueckner's sordid criminal past, said Maddie was potentially just as much of a target for Brueckner as his elderly victim.
"It's really important to understand that many child molesters are not paedophiles. So for them, it's not about the young age itself, it's about weakness, it's about vulnerability, and it's about feeling some sense of power. So they like to attack 'easy victims'," he told the program.
I'd wondered about the discrepancy in the age of victims (and even gender) in a few other cases. I'd read the substance of what Hoffman says some time ago, and it makes sense to me (irrespective of whether he's involved in this case).
