“This is such a very different type of DNA testing than people know about. It's very different from forensic DNA analysis, where you are trying to match a sample to a specific crime suspect. This is kinship, and you will never get an exact match between a mother and a son. You get what's known as a probability of a relationship.”

“Of the almost 1,500, we suspect there's a 'nugget' who are truly missing ? washed out into the Gulf. Then there's a small subset that honestly don't want to be found. How do we know when we're done? How long do you keep looking? What do you do when you've done all the DNA testing you can, when you've called everyone and you still can't find the person?”
