Kids who torture and abuse animals are often let off even if they're caught, because LE don't take it seriously.
The image of this guy just shouts out misfit, loitering and unkempt. Someone women of his age recoil from and reject which makes him angry.
He's probably someone who doesn't fit in with his peers, doesn't have a meaningful career, never established committed ties in his community.
The girls likely picked up on these signals which is why his voice and image were recorded.
He's not a typical "BTK" type as yet.

Just because he hasn't been caught doesn't mean he hasn't committed acts of cruelty, theft and other deviant crimes that flew under the radar because he's sneaky, cunning and lucky.
Its unlikely that someone would just be driven to commit something as serious as murder and possible sexual assault etc (details of the murders not released by LE) without trying out other thrill crimes and deviances first. And although we don't have the details of the murders yet, I have a horrible feeling they were sexually inclined.
The grainy image of BG doesn't strike me as someone clean cut or upwardly standing in the community. He looks menacing and unkempt, someone who doesn't really fit in and resents it.
He's done other stuff he's gotten away with and he's escalating, sloppy and is probably trembling after realizing he's not as clever as he thinks he is after the LE info released on the 22nd April.
