I have read hundreds of those style of affidavits and that one is really really clean. I mean, they usually are/have to be, but they did excellent work in this case. Aided by the FBI, for sure. It reads like a federal charging document.
For all his intelligence and master PHD, he was just a sloppy, obsessed, angry maniac. Left his DNA on the scene in a sheath. Parked his own car the scene. Didn't think about the cameras, and the residential neighborhood, which wouldn't obscure him or his vehicle.
Seen and read a lot on this case, and a lot of others, and this was still chilling. That mask, seeing the killer. Hearing him. Wow. Doesn't expand on any links to the victims, besides he for sure knew them, and stalked them. Doesn't go to motive at all, that will be maybe in the prelim. Think they redacted some of the more grisly details. Not sure 100%.
Really glad it's solved, and he will max out with a life sentence. Probably get 300 years on some county technicality.
They even did the kind of reverse cellphone tracking that provides evidence via exclusion, as opposed to inclusion,I saw used in my friends death prosecution too. As in, his phone was everywhere, but during those hours of killing, it wasn't. And then came back on right after. Just a minor thing but weighed with everything else. And they do have an eyewitness. They were on him as soon as a week after the killing or maybe 10 days.
