Highly intelligent? Retired professional? No criminal history?

That would describe the BTK Killer as well, except that in his case he was just months from retirement.

Nor would it be an inaccurate description of Ted Kaczynski.

These attributes are not really probative of anything.

[Dead Corpse]

And you still miss the point...

Know what the difference between Ted/BTK and this guy is?

THIS GUY DIDN’T HUNT DOWN HIS VICTIMS.

He WAS the victim.
