This news article is not exactly on point, but it’s just so damn relevant (plus I saw it on CNN this morning and I thought you guys might be interested). For the link impaired, it’s about twin brothers embroiled in a paternity suit.
Hmm. I’d say if the twins actually testified under oath to their alibi, then they screwed up, because now they can both be convicted of perjury (and/or aiding a criminal, conspiracy, etc.). After all, they can’t both have been at the movies, so twin A either lied about being at the movie, or lied about twin B being there.
I remember the bone marrow donation angle from somewhere, but I know I haven’t read any Kay Scarpetta mysteries. It might have been an episode of CSI or another police procedural.
The uncertainty caused by identical twins was indeed a Without a Trace episode, from 2 seasons back IIRC.
**CSI **(also, 2 seasons back) had an episode where DNA didn’t pinpoint the actual killer (at first) because he had chimera syndrome, and carried 2 different sets of DNA.
Well, possibly I’m deranged. My memory is like a lumber-room, in that it has lots of bugs and sawdust in it. At least I didn’t confuse the plot with that one episode of What’s Happening? when Rog’s evil twin* showed up.
Now I wonder if anyone’s done the reverse of the story-- where somebody gets away with murder because their DNA has somehow changed in the meantime. Or was that the plot of The Shaggy D.A.?
*I think it was his evil cousin, actually. To my recollection, no DNA was harmed.
If only I had thought to mention that in the OP!
When I get a million dollars for my screenplay, both you and Chronos are officially uninvited from the celebration party.
I think I might have read that Kay Scarpetta mystery - the title might be “All That Remains”.
:smack:
I read the OP carefully, I promise. Only I read it yesterday. Here’s another headsmack for good measure: :smack:
Don’t smack yourself too hard, Campion did the same thing.
I don’t remember if there was a DNA angle, but multiple identical people factored heavily into the plot of Ken Follett’s book The Third Twin.
It’s been a while since I’ve read Presumed Innocent, but I don’t remember DNA evidence coming up(mostly because the defendant was found not guilty without the crime being solved, and there’s no way that he would have been found innocent had his DNA been found at the scene).
Although now I have a hazy memory of the medical evidence being discredited, so many DNA evidence did come into play.
[spoiler]It wasn’t DNA, as that test wasn’t really an option then. The semen found in the dead woman matched the guy’s blood type, and they were able to prove he was having an affair with her. But when the lab found spermacide in the semen, but no source for it at the scene, the defense argued that the lab sample must have been mixed up or corrupted somehow.
But it turned out that the real killer had placed the semen there after obtaining the sample from the protagonist herself in the usual way. Except she used a diaphram, thus the spermacide.[/spoiler]
Thank you, Saltire, for clarifying the details. Now I won’t have to re-read the book in question. (As I recall, it was a book I finished because I “needed” to figure out how things were resolved, rather than because I was enjoying the book so much. )
Just the reaction I was looking for to get the evil twin to give himself away. Take 'im away, boys!
