This episode was reported and produced by Meradith Hoddinott and edited by Katherine Wells, Noam Hassenfeld, Brian Resnick with help from Mandy Nyugen and Byrd Pinkerton. Music by Noam. Cristian Ayala handled the mixing and sound design. Research and fact checking by Richard Sima. Tori Dominguez is our audio fellow.
