I remember watching a case on television in which the young woman who had been snatched and abducted was sure she was going to be ultimately killed. And she was.
But what led the investigators to know that she anticipated her own death was that they found her DNA via epithelial skin cells all over the backseat and interior of the car in which the attackers placed her.
They found it on the doors, the ceiling, the seats, the floor. In the most obscure nooks and crannies.
They found it in places it would not have been even in the midst of a brutal attack and killing.
They were able to tell that that poor young woman intentionally touched everything she possibly could, rubbed her arms on all surfaces, leaving her identity behind.
She was removed from the back of the car, brutally bludgeoned to death and then buried in an obscure and well-hidden grave.
She was reported missing by her family. Weeks later when an abandoned car was found a state away, her DNA was all over the rear interior of that car.
Her case as a missing person was very active. The detectives were on it and the tests they ran told the story. They knew that she had been in that car.
That determination led them to further locations and ultimately to her grave, and her killer.
That young woman did the only thing she could do to make sure someone knew where she had been and what had happened to her in the event of her violent death.
She left a message for everyone.

Jan Roseboro did the same thing.
In her fight against her attacker she scratched him as he subdued her and killed her.
And in her hand was his identity.
It didn't wash away.
It wasn't diluted beyond analysis.
If Jan was attacked by robbers, she would have fought back just as hard.
She would have their identity under her fingernails.
Despite flailing and struggling in the pool, that DNA remained....
Thank God it did.
It's Jan's way of telling us all who brutalized her and broke her.
I pray the jury is truly listening.
