    I think he knows he's going to be found guilty. And is enjoying putting all these people through a bunch of shit. He's smiling half the time

    This guy is sick!  I would look for more bodies in every city he has ever lived in.  He didn’t just develop coping skills that involve murder.  His psyche is truly warped.

    What evidence of actual consumption of the succinylcholine is there?  How much succinylcholine is missing from the vial?  Any?  Is it just an unused vial?  Are there any used syringes? or just unopened sterile syringes?  What evidence is there that Kosowski actually injected Cozzi with the paralytic before killing him?  These details appear to be suggested but are missing from the Prosecution's Case.

    This monster is just having fun with all this. He’s just extending material for his Netflix horror movie and his book! SOAB

    He wants all the evidence suppressed..... definitely the workings of an innocent man isn't it?... not!
