Today's episode of Katie was dedicated completely to last Friday's Sandy Hook shooting. Katie Couric spoke with a handful of people during the show: a pastor, a family who lost a child at Columbine, but nothing was more heartbreaking than hearing from two families who had lost children just three days ago.

Couric sat down with Alissa and Robbie Parker, who lost their 6-year-old daughter Emilie. We heard a bit from Robbie Parker over the weekend. Couric also aired an interview with Jackie and Mark Barden — the first time they'd spoken out since the death of their son Daniel. The Bardens also brought along their oldest son James.

You can see the interview with the Parkers on the show's website.
