Docs Say Serial Killers Have Specific Genes

Some serial killers may be born, not made.

Scientists suggest there are genetic triggers that can actually "create" a murderer.

For years, they've been studying the minds of criminals, including those who've orchestrated some of the most heinous crimes imaginable.

Now researchers say the brains of mass murderers share a great deal with certain abnormal brain structures, like the gene cadherin 13.

One version of the gene has been connected to impulse control in extremely violent offenders. And there's even more evidence to back up this theory.

A psychologist working with imprisoned psychopaths came to a similar conclusion after collecting data from more than 4,000 criminals. He discovered they had less gray matter and smaller amygdalae.

Another expert studied 135 serial killers and believes many of the ones out there have an extra chromosome in their DNA.

Your weak ankles and predisposition to high cholesterol don't seem so bad anymore, do they?
