The parents of Emilie Parker, one of the 20 children who were killed during the Sandy Hook Elementary School shooting in Newtown, Conn., discussed how they are coping three months after the accident and said they met with the father of the killer.

Robbie and Alissa Parker, the parents of the six-year-old, spoke with Norah O'Donnell on CBS This Morning and when they were asked why they met with Peter Lanza, the father of gunman Adam Lanza, Alissa Parker said it was "her doing." The interview aired on Thursday.

"I guess the reason why I felt strongly that I needed to tell [Peter Lanza] something. And I needed to get that out of my system. I felt very motivated to do it and ... I felt really good about it, I prayed about it, and it was something that I needed to do," Alissa Parker said in the interview.

There weren't any details regarding what the Parkers spoke with Peter Lanza about, or when they met.

According to WCVB, Robbie Parker was the first parent who lost a child during the massacre to speak publicly. On Dec. 15, a day after the shooting, he said of his daughter, "I'm so blessed to be her dad."

O'Donnell asked the Parkers what they thought when they heard that Adam Lanza, 20, kept a spreadsheet that detailed the death tolls from other mass shooters. Alissa Parker said information like that always brings sorrow and pain, but they deal with it and move on.

Alissa Parker said, "The outcome is still the same, regardless if it was planned, not planned. But it doesn't change anything. It doesn't change that our child's gone."
