Perhaps he drained the body into a tub/Shower or sink first, The best he could?
I mean- I'm not an assassin but if i was gonna disember somebody, I'd be overdosing them on Heparin and cutting a toe off first? Maybe going for an artery? For hopes of less cleanup?
For someone scatterbrained enough to use company cards to purchase cleaning supplies, etc. it's not likely he was in a state of mind to do something like that - however, that is of course, conjecture, and further information will have light shed upon it during the proceedings.
Depending on how one is injured, bleeding may not become apparent on the outside, rather damaging the internal organs to the point of failure. Allegedly the perpetrator had quite some time to consider next steps, so all anyone can do is surmise.
I truly do not want to sound rude, though a toe even with a blood thinning agent, is highly unlikely to cause death, nor is moving a human, even 100lbs, & unable to support themselves a struggle. If you've carried a friend home from a bar or something, you'll understand how incredibly difficult it is to even get them in a taxi.
It is a sad thing, but perhaps the man charged doesn't have true family nearby for support or readily available consolation during these especially stressful times (no....not over yet....) - to check on him when he hasn't been answering the phone amidst a pandemic, often alone or feeling alone - someone to talk through the stress and provide coping mechanisms, etc. - and we all don't know the specifics of what said accused had been going through or gone through his entire life leading up to this. I do not want to judge him, as I do not have all the facts, and conjecture at the moment seems a bit hasty. I'd like to. I really would. However, I'm not a forensic pathologist, I do not have a PhD or MD. I do know people have been acting out of line the past months (to put it lightly), and terrified for their futures.
The Saleh's would not want the wrong man convicted - especially with the gossip of some widespread conspiracy, coverups, etc. All of this is conjecture I can only disappointedly shake my head at, as well. A family that close would know of anything going on and no, they wouldn't lie under oath - for example, I'd rather give my best male (straight) friend a set of keys than my brother, and that's not just for logistics. We're just not that close! The Saleh's are a close, loving family and even should this man prove innocent I highly doubt they'll feel a sense of security in their homes, if ever.
The reporting on this case was hasty. First a sister, then a cousin, etc. found the scene, though it seems as though a haphazard attempt to conceal and clean was attempted....This is something that needs forensic specialists and will be provided as time passes. Until then, we have no information other than what is provided by actual witnesses,, people on the scene, and other forms of evidence.
Perhaps as often happens, critical information is left out from the public to help correctly identify the perpetrator, though from all upstanding sources it seems as though the perpetrator took some time. Even by purchasing birthday gifts for his girlfriend to claim it is as diversion of speculation is conjecture. Personally, I have no clue what goes on in the mind of anyone potentially capable of doing that even to even an animal - most certainly not a human being.
