Man Linked to Child Sex Crimes by DNA Has Mind-Boggling Defense

If your DNA ever links you to a series of horrific crimes, you're screwed. Unless you just happen to have the single most fortuitous twist working in your favor to cast some doubt on a DNA trail. And that is that somewhere out there, there happens to be someone with your exact DNA. Your twin! Thirty-two-year-old Aaron Lucas' DNA reportedly links him to a series of child sex crimes. But Aaron has a mind-boggling way of pointing the blame elsewhere -- he says his twin brother, Brian, is the real sex pervert. It's a plot straight out of ID channel's Evil Twins.


Aaron, who is an Army officer, has been linked to sexual assaults on children in three states. Prosecutors say that the child victims would be attacked after being lured into interaction with promises of ice cream and money.

But Aaron's defense attorney is putting forth the "evil twin" defense -- saying that Aaron's brother Brian is the real culprit in many of the crimes. Brian has not been charged with anything.

This is one of those extremely rare scenarios where DNA is anything but a slam dunk, given that identical twins share DNA. So imagine you are a twin and your brother or sister has been accused of a terrible crime and he or she is suddenly pointing in your direction as the real criminal.

More From The Stir: Healthy Twin Brothers Euthanized Because They Were Going Blind

And imagine the reverse: That cops have your DNA linked to several horrible crimes -- but you KNOW you didn't do it. Could it have been your twin? If so, how can you prove that?

One of these guys is lying, but who?

Before science got to the point where DNA could solve crimes, it was left to good old-fashioned detective work. There is no doubt that DNA has been a boon to the world of criminal investigation. But it can't be the only thing that gets a conviction.

Hopefully there is some other evidence in this case. But with the brothers also looking exactly alike, eyewitness accounts won't help much either. There does reportedly appear to be some circumstantial evidence that doesn't bode well for Aaron: Such as that the attacks began after he moved to the area and stopped when he was deployed in Afghanistan. (His lawyer might argue that a clever twin could have set that up.)

Cops just got double the trouble on this case.

Do you think this guy should be able to have his brother investigated too based on his sharing the same DNA?
