In this case (rape and murder) the DNA is likely to be haploid DNA from sperm cells.
Did the cop give a hand job to the person they wanted to frame for the crime prior to planting the evidence?
How does a cop go about collecting patsy DNA and planting said DNA at a crime scene?
Did he also get a skin scraping to plant under a woman murder victims fingernails?
How does this planting of DNA go down? I really want to know.
Did I say EVERY cop plants evidence? In this case, there was none.
How easy would it be? A cop can take a cigarette butt from the interogation room then go back and plant it at the crime scene. Or he could take a blood sample and some of it go missing. And have you never heard of a “throw down weapon”? Just a few examples.
In this case, cops flat out lied and failed to follow up on other leads.
