I’m not sure if this post is addressed to me, but I have no idea what your point is.
If I were the police at this point, I would investigate the person whose DNA was found on the victim.

Great plan. Watch a lot of cop shows, do you? I do, too.
Are you aware that the police do not, in fact, have a database containing the DNA profile of every person in a particular area? at best, they have some profiles of some known offenders, but it doesn’t seem to work like you see on cop shows - they don’t simply take the sample, and ‘run it through’ and a name pops out.
There’s a local case for me where a woman was killed about two years ago. She was found, DNA under her fingernails, she’d fought the attacker, a rather gruesome attack. Cops ID’d a local semi homeless guy w/a learning disability, who had habitually hung out where she was found (local community college - he was taking classes there). they questioned him for hours and hours, finally coming up w/a statement that they called a confession wherin he said stuff like “if I’d done it I had to be sleepwalking or something”. They used that extensively during the trial. They found a fiber on him that was ‘similar’ to one from her coat/sweater (of course, since she taught at the college and he lived there, the presence of a single fiber shouldn’t have been a surprise - I suspect if you search 3/4 of the people I work w/, you’ll find fiber and hair evidence of contact from me as well).
he was convicted and sentenced to life. Funny thing, before the trial, the cops had a surveilance video taken the day of the killing, a short time before, showing him quite a distance away, so he’d have had to RUN there and quickly murder/rape the woman and quickly exit w/o being detected again.
And, of course, they’d found DNA under her fingernails. It did NOT match the suspect. Didn’t matter.
They’ve released him. They have some one else in custody now who they suspect really killed the woman. You know what? they had the second guy’s DNA available at the time the woman was killed. Apparently, the DNA discovered under her fingernails wasn’t screened against known offenders at the time.
