That DNA you send in the mail can help trace your ancestry. It can also get you arrested.

The Miami Herald reports:

Trying to unravel the mystery of your genetics through programs like 23andMe.com or Ancestry.com can also help police unravel a criminal investigation.

That saliva sample sent to those genetic testing companies with the purpose of learning more about your ancestral history doesn’t just belong to you.

With a warrant, it can also belong to law enforcement, company officials say.

With the genetic information it gets from the organizations, police can identify suspects in a criminal, credit or identity theft investigation. So far, officials have requested information for five U.S. 23andMe customers, according to the company’s website.

For you rookies out there.
