One viewer wrote in on Facebook and asked the producers, "What's the toughest assignment you've ever had?"
Co-producer Jen Stamper says the hardest assignment is always talking with someone who has recently lost a loved one. "It's obviously very emotional, and you try to stay professional," she says. "You don't want to make them feel worse than they already do, and they're sharing such intimate moments with you and such personal feelings."
Five years ago, Jen worked on a story about a mother whose daughter had been abducted and brutally murdered. "I was trying so hard to keep it together and listen to her story, but it was just so heartbreaking, and I couldn't. I lost it. I couldn't even speak to her, and I was crying so hard, I had to apologize and explain to her, 'I'm so sorry, I have a 2-year-old at home; I'm about to give birth to two more little girls, and the story is just touching me so much.' I was just a wreck."
