I don’t think this was BKs first murder

I am finding more and more connections between this case and BTK. I’m from Wichita so I know the case WELL since I was around to witness it. If you ask anyone in Wichita they’ll tell you they don’t think the Oteros were BTKs first murder(s). We all feel he won’t fess up because the DP was struck down only 2 years prior to the Oteros murders. It is speculated he is connected to at least 5 other cases. Kathrine Ramsland has even asked the same question if there are more. A common thing we see with these types of killers is a behavior escalation and unraveling which often leads to their arrest. In my OPINION. Based off the facts of the case and how sloppy he was: google searches, not surveying the fact that there’s cameras in the neighborhood, the sheath, buying another knife, the obvious crime clean up, brutality of the murder and amount of people involved, going in only minutes after the lights turned off. All this DESPITE being a criminology phd student just seems crazy. His parents even had to testify in PA on a missing person case recently. Not saying the family are bad people but from what I’ve seen, the mother often made excuses for strange behavior of Brian’s growing up. I wouldn’t put it past to go to extreme measures to protect Brian. Again, just my opinion. What do you all think?
