Sometimes the government calls me to help solve mysteries, like this time in 1993. One of their officers told me he had spotted some suspicious packages at Kennedy Airport in New York City. These boxes contained handbags and shoes.

By looking at the pattern on the reptile skins, the officer had a hunch they were made from Yacare caiman, a relative of the crocodile and alligator.

My blood started to boil. "But the Yacare caiman is a protected species," I said into the phone. "Bringing skins of that animal into the U.S. is against the law!"

"Exactly!" said the guy at the U.S. Fish and Wildlife Service. "That's why the officer seized the shoes and handbags from the reptile skin importer."

"So, what's the problem?" I asked.

"The importer said it was not a protected caiman," he said.
The importer claimed that it's impossible to tell the difference between caimans just by comparing skin patters. This disagreement went to court. And that's where I came to the rescue.

First, I took samples of the reptile skins to my lab at the American Museum of Natural History. Then, I made lots of copies of the the DNA, so it was easier to study. Next, I used a machine to figure out the DNA's sequence, which looks like a long string of letters. Finally, I compared this skin's sequence with other crocodilian sequences in our DNA computer library. It was a perfect match to the Yacare caiman! Those shoes and handbags were definitely made from a legally protected species.

I gave this report to the judge. Based on the DNA evidence, the judge agreed that the skins were illegal. The skins were taken away and the importer had to pay a fine.
