    DNA technology has advanced a lot in recent years. Touch DNA means “trace amounts of skin cells, sweat, or other bodily fluids left behind on an object when a person touches it”
    which basically means: if you touch it, your DNA will be left behind.
    Skin cells are constantly flaking off and being left behind… actually that’s what most household dust is from.
    Hair is constantly falling off as well, if a follicle is attached, that has DNA….
    On top of that, your microbiome, the billions of bacteria living on and in your body, all has unique DNA that can be solidly attributed to you…
    Even if he cleaned the bullets well there would’ve been DNA in the magazine that could get on the shell… his breath is constantly shedding DNA….

    If someone came up and shot me on the sidewalk, i wouldn’t get the full CEO forensic treatment they’re giving this case though….
    ….
    there’s been speculation that we have less serial killers and more spree/mass murderers because they know that can’t get away with it anymore… and people who try to be serial killers get caught after their first couple of victims.
    ….
    Luigi would’ve gotten away with it in 2005, but not 2025….
    btw, there’s also a loooot of surveillance cameras in NYC… they didn’t release everything, just a few pictures so the public could help identify him.
    p.s. Jury nullification got the guy off for throwing a sandwich and federal officers in DC recently….

      I didn’t know the science had come that far. I assumed anything useable would just go away unless it was instantly preserved.

      And that’s a good thing to know about serial killers, but I guess it makes sense why most of those true crime things are in the far past.

        well now the key is to leave no body or crime scene to be investigated… even then, cell phones are constantly tracked, surveillance cameras are everywhere…
        one reason “the ice man” used to freeze his victims for months before dumping the body… without a proper time of death it’s hard to find him on cameras. (and most places don’t keep security footage for too long).
        With this chief shooting, the crime scene was immediately preserved… cops were called immediately.
        Also the NYPD has a police force larger than many countries armies.
        another scary thing with DNA is if they don’t have you on record, they have some cousin on record and will then just investigate everyone related to them and collect their DNA from trash and stuff….
        of course, that’s only if you kill someone rich or a white girl or someone “important” enough….
        I guarantee they’re not collecting dna from shell casings after drive-by shootings in poor neighborhoods….
