Some good points there. I didn't really approach it from that perspective of a 'standard' serial killer because there was no difference between the assaults. BTK would quickly kill those he didn't want (like that family where he was really after the little girl and did his weirdo hanging job with her but killed the others quickly) whereas this sicko killed all 4 students/roommates with the same method and same level of overkill. Richard Ramirez was the same - as was Joseph Deangelo - kill off the men quickly and have his sick fun with the women. Whatever this is - it's not the usual serial killer type. All 4 killed with the same method in the same rage. There's something very different about this dirty bastard of a scumbag.
I think you're right about the 'cool off' periods. To me - this is more of a spree killer freak which is why I'm surprised there's been nothing else which brings me back to the original assumption that it's either that OR someone that was known to at least one of the victims.
I'd expect a methodical serial killer to be into something a little more practiced such as bondage/cable ties/prolonged sadism such as strangulation and release but this is just some crazy overkill thing. I'd understand if the 3 other victims were quickly stabbed up and he focused on the last victim with some kind of sexual/sadistic type prolonged shit but this is just like a conveyor belt of stabby stabby next stabby stabby next. As if he hasn't taken the time to 'enjoy' his work.
Fucking shame they haven't caught the fuckhead yet. There's got to be DNA just got to be something.
Thanks for the comment and feedback.
I agree, this does not seem like the typical serial killer--as you say, seems more like a potential spree killer. I didn't think of that. I would imagine if this was a typical serial killer, as noted by you, there would have been a difference between the killings or possibly a sexual assault involved. But, given that all 4 were killed in the same exact way and no sexual assaults, it has the feel of a spree killer. On the other hand, maybe it is a serial killer, who just went in, did the job and left--kind of broke rank and didn't follow his usual trends/killing routine--but that's likely a stretch since serial killers tend to be pretty obsessive about their routines. To be honest, I have no idea.
Usually serial killers are much harder to catch than spree killers, since spree killers are just so haphazard and unrestrained. You would think if this was a spree killer, he would have left something behind, some sort of evidence. This person REALLY covered their tracks. If this was solely the work of a spree killer, it definitely leaves a lot of questions open. Biggest question is "Why them four?"
