Not that this is likely, but..
what if the shooting deaths were just a means to an end, ie. the "pleasure" being to dismember human beings,''pack'' them and leave the bags at a beach to shock and horrify not just the person who finds them, but the whole community? speculation, imo.
Exactly. Just knowing the erm variety of ways serial killers have operated, I don't think I can be too shocked anymore. But I absolutely agree there is meaning or significance to the killer in terms of weapon choice, intent, disposal. I think that's largely where the organized/disorganized killer comes from, right?
Like, a disorganized serial killer is a Richard Speck type. Picks a place at random, terrorizes with "overkill" in a fury rather than as a plan, leaves a lot of evidence, already has a record and a history of dangerous behavior, low IQ, history of abuse, etc. This person would have a gun and would use it because it's there, or they would use a knife because it's there, or a rock because it's there. There wouldn't be thought to the strategy, if you will.
Then you have your organized killers, the GSK or BTK type who hyper-plans everything, is ultra careful, and presents a totally normal face to the world. LISK is in this category according to FBI profile. This person is expected to be a man of some wealth, has a job, has an SO. And it's in this category where I think you find a Zodiac, someone who uses a gun for expediency. Zodiac got off on the media attention and the communicating with police more than the actual acts.
So if this Seattle dismemberment situation is a serial killer, I think you look at the gunshots as expedient and thus intentional, meaning organized. Then you have the dismemberment. Why dismember? Two bodies are heavy. Hard to move around. Maybe this killer doesn't have a car or easy transport? Kill location was too visible? Or, could it be a woman? Guns and dismembering make it easier to kill someone and transport rather than overpowering someone with a different weapon. And then you need to dispose somewhere. Why near Pike Place Market? High traffic, of COURSE they would be found. So maybe that speaks to that FBI profiler comment about this person wanting to get attention? If you really want to hide your tracks, you dump that stuff somewhere remote, not near the tourist boats. So if you want bodies in suitcases to be found in downtown Seattle, then yeah, I'm with
@dotr on this above, you want to scare people. If this happens AGAIN then I think we know the situation for sure.
I found
Patrick Kearney was a gunshot and dismemberment type. Seems he would pick up men in his automobile and while driving on a highway would shoot the men in the head almost immediately, let them stay slumped against the doorframe, and then take them to remote locations. He was a necrophiliac so it seems that was the real goal, not the kill but the body. Then he dismembered and disposed in bags all over the place. I guess he's one of three who have the "Freeway Killer" moniker?
