Been following the Steve McNair/Sahel Kazemi case all day like you, and the evidence now looks pretty damning that she did indeed murder McNair and kill her herself. The gun residue results will likely confirm that in short order.
(Steve McNair’s mistress - and killer? - 20-year-old Sahel Kazemi)
If the residue on the gun is from Kazemi, it’s laughable that police would continue to maintain that they may never know the motive of the crime. It’s opposite day! We all know why she might do the deed - but god knows most of you reading this wouldn’t take it that far, if placed in a similar circumstance.
If she didn’t do it, it would take a sophisticated criminal to have possession of her newly-bought gun, get a key to the condo and have the presence of mind to kill both parties and then mask the murders by placing detectable residue from Kazemi on the offending weapon.
(Kazemi’s Ex Keith Norfleet a criminal mastermind? Probably not)
Knowing the possible suspects that are out there (see above), I highly doubt that any of those folks could pull off such an insidious, sophisticated crime.
Though anything is possible.
