Is this less common knowledge than I thought?

I'm watching my way through a show called 'Forever' at the minute. Immortal Medical Examiner currently working in New York. It's enjoyable so far, actually. I'm only on episode 6, "The Frustrating Thing About Psychopaths".

This episode itself, however ... Okay. A cop has a human heart delivered in a package to his desk. They determine it's the heart of a very healthy 25-30 yr old woman killed in the last 3-5 days, and look up missing people for that time and criteria. They find a call girl/prostitute operating under the pseudonym 'Mary Kelly' (which, by the way, whole other kind of tempting fate, right there). None of them twig. None, except the 200 year old ME.

How? Seriously? How does a whole room full of cops be presented with a human organ delivered to a cop from the murder of a prostitute named Mary Kelly, and not come to ONE CONCLUSION?!? Like, even if it's the wrong one, how do you not come to it?

It's the right one, by the way. It is a copycat. Not really a spoiler. And to top this all off, when said ME is explaining that the original Mary Kelly murder was the last and most brutal of the original killings, one of the cops asks him why, was the killer was caught after that? The name has been named, by this stage. They know who the guy's copying. (Though all the other cops have actually started remembering shit by now, so maybe that one was just a little dim).

Honestly, though. Hasn't every crime show ever done some kind of Jack copycat? How do they not twig when Mary Kelly comes up? I'd have thought a large portion of joes off the street would have started suspecting at that stage, let alone a room full of cops.

*flaps hand* But. Nevermind. The episode is pretty good, that bit just broke my suspension of disbelief a little bit. My apologies for the random rant.

Word Placement

Something I saw on tumblr. Might actually be useful to me as a reminder since I have a strange tendency to arrange words oddly sometimes when I'm writing in a hurry.

Place the word 'only' anywhere on the sentence:
"She told him that she loved him."

- Only she told him that she loved him. (She was the only one of six women that did)
- She only told him that she loved him. (Like what else was she gonna tell 'im?)
- She told only him that she loved him. (No-one else. They eloped the next day)
- She told him only that she loved him. (She considered it the only pertinent fact)
- She told him that only she loved him. (So you're not getting any better offers, boyo)
- She told him that she only loved him. (Not that she was willing to die for him, WTF?)
- She told him that she loved only him. (No other man for her. Honestly, your honour)
- She told him that she loved him only. (... to stab him through the heart?)
