My niece wants to know: if she donates her hair to Locks of Love, and the recipient of her hair commits a crime and leaves hair at the crime scene, will her DNA be found all over the crime scene and thus incriminate her? She's 12.

In addition to the donated hair lacking DNA, they can only do DNA matching against samples they already have or could legally acquire (generally with a warrant).

So if she's not otherwise in their system or already a suspect, she should be in the clear!

    Turns out you can use DNA from relatives too. And with large databases of ancestry this can go up to 4th cousins and narrows it down from there.
