I agree, I'm not surprised he took the time to plan "the perfect crime" as per his statement in the CC. Notice, he didn't say anything about being remorseful, offer any explanation that we know of as to why he did this other than he saw Jayme and knew he was going to take her.
It was important to him to come in military style, big, bad boogey man, kill his targets James & Denise, and take off with his captive. It was a scenario he's probably fantasized over many times and I wonder if he didn't have this abduction style planned out and then ran across Jayme as his 'victim'. I do think her physical traits played into this somehow.
JP went to the house on 2 other occasions, he was a COWARD then, afraid because others were there. He struck the Closs family at their most vulnerable time, in the most shock affecting blitz style because it was always his plan and the only way he could pull it off. He's weak at life and probably always has been. IMO
I have no sympathy for the defendant. I sleep better knowing he's in a cage and will spend the rest of his miserable days there.
