DALLAS -- A couple's newborn baby was switched in the hospital.

Mercy Casanelles gave birth at a hospital in her home country of El Salvador.

But before the she and her husband returned to their Dallas home, Casanellas says she felt something wasn’t right.

She says the baby she was handed at the hospital looked different from the one she held in the delivery room.

Genetic testing was done on all the baby boys born in the hospital the same day as their child, and the tests show the baby could not be their biological son.

The couple has since been reunited with their baby. They now live in Dallas.

Now, the doctor has been taken into custody for allegations that he may have been operating a baby trafficking gang.
