"He said, 'I need to have people think highly of me, have a high estimation of me,'" Poole said. "He said, 'All my problems have stemmed from my wanting people to be proud of me.' It seemed so sad, in a way." (

My armchair opinion of TF stems directly from this comment. TF failed a bunch at his endeavors for a variety of reasons, but one thing he had going for him was his looks and seemingly boyish, coy affect. He put women at ease. In reading further through the above article, one will see that he stole from the owner of Deby's, lied to her, manipulated her, and yet she still let him use her office, let him sleep there, and talked to him. He even had another "girlfriend" so brainwashed that she let him use her car/jeep? to take to Austin when he moved earlier in the year.
The fact that TF then went on to look at missing women on the internet tells me he that he found his "pride" eventually in killing, frustrating investigators, and thinking he was getting away with murder.
He probably met Amy the same way he met Kenia and the Ft. Collins woman - by chance at a social event (Kenia at the club and Ft. Collins woman at the 4th of July celebration). By all appearances, he seemed like a nice enough guy. He would have to me.
Just like Ted Bundy.
