They killed LB the day it crossed the border and was about to arrive at the hangar. There was zero contact between the two we are aware of that would led to LB being killed on that date. The threatening texts occurred months before. The only variable that changed was DM got a gun and the incinerator is about to arrive.
And the virtual eye rolling is because the scenario that the incinerator is going to feed some kind of roaming body incinerating business is more ludicrous than a roaming animal incinerating business. Let's not forget the purchase was only made because the homemade one was a failure.
First of all, who is killing all of these people that they need to burn bodies? They need to have crazy money and kill at some kind of record pace to earn DM a significant amount of money. Second, driving an incinerator around is about the easiest way to draw attention to yourself, no one with a brain is going to kill someone than have someone drive up with 7 foot tall incinerator to burn bodies.
Occam's razor. Yes it is possible that the purchase of an incinerator and the killings are exclusive events. But the most plausible and simplest explanation is that they are linked.
DM already had a gun for months. He got the Walther at the very least in February. Again, you’re drawing arbitrary lines through events that there is reason to believe are not even connected and calling that obvious. It’s not obvious. We don’t even know when DM and LB got back in communication or who initiated it. From the evidence we have in this trial, she called him first on July 1. Plans heats up on an incinerator after DM breaks up with CN and before he gets back with her. Why? Certainly not obvious!
The idea of incineration for hire is just one thought that could make a 15,000 incinerator make some sense - in Dellen’s head. It doesn’t actually have to be realistic. He’s desperate for a gun in January “cause he’s under pressure and stuff’s gotta start happening”. What pressure? What stuff? Not obvious!
