One of the Biggest At-Home DNA Testing Companies Is Working With the FBI (buzzfeednews.com)
An anonymous reader quotes a report from BuzzFeed News: Family Tree DNA, one of the largest private genetic testing companies whose home-testing kits enable people to trace their ancestry and locate relatives, is working with the FBI and allowing agents to search its vast genealogy database in an effort to solve violent crime cases, BuzzFeed News has learned. Federal and local law enforcement have used public genealogy databases for more than two years to solve cold cases, including the landmark capture of the suspected Golden State Killer, but the cooperation with Family Tree DNA and the FBI marks the first time a private firm has agreed to voluntarily allow law enforcement access to its database. While the FBI does not have the ability to freely browse genetic profiles in the library, the move is sure to raise privacy concerns about law enforcement gaining the ability to look for DNA matches, or more likely, relatives linked by uploaded user data.
The Houston-based company, which touts itself as a pioneer in the genetic testing industry and the first to offer a direct-to-consumer test kit, disclosed its relationship with the FBI to BuzzFeed News on Thursday, saying in a statement that allowing access "would help law enforcement agencies solve violent crimes faster than ever." While Family Tree does not have a contract with the FBI, the firm has agreed to test DNA samples and upload the profiles to its database on a case-by-case basis since last fall, a company spokesperson told BuzzFeed News. Its work with the FBI is "a very new development, which started with one case last year and morphed," she said. To date, the company has cooperated with the FBI on fewer than 10 cases. The Family Tree database is free to access and can be used by anyone with a DNA profile to upload, not just paying customers.

They don't need your DNA, just someone close to you in the family tree, and they'll basically have your DNA as well.
What you mean is they don't need the perpetrator of the crime to have been tested by Family Tree DNA, they just need your sample collected at the crime scene to match for distant relatives.
Articles about the discovery of the Golden State killer suggested that third to fifth cousins would be about the sweet spot for getting a match. Any further back and there are too many possible suspects and any earlier then you may not get a match at all.
Once you've found a distant relative then the information is given to a genealogist who works forward to narrow the field down to one or two suspects. After that they follow the suspects around and pick up discarded drink cans, straws, condoms etc. to get test for a definitive match.
