Help me understand!

New to this case and feel like I must be missing a lot of info. How is it possible this Allen guy never committed any other crimes? No history of anything? Nothing violent, not even a bar fight or something? And just escalated to double murder? And then never did it again? This is truly mind blowing to me. I’m sure this guy did it but it’s just so shocking this guy went from zero to double homicide.

And what is the suspected motive? He just always wanted to do it and finally had the opportunity? He snapped?

I’m so very confused.

There have been a few cold cases like this that have been solved with DNA recently. The murder ends up being some random Joe with no criminal record or history of violence, yet they committed some horrible crime. I agree it does not fit with what we think of in regards to suspects. Maybe that one crime was enough to satisfy their rage?
