Krista Rekos spoke to ABC News about her daughter, Jessica Rekos, who was killed on Friday in the Sandy Hook Elementary School shooting attack in Newtown, Connecticut.

"We will talk about her every day, we will live for her," Krista Rekos said. "We will make sure her brother knows what an amazing person she was."

The younger Rekos was one of 20 children allegedly shot by Adam Lanza in the Connecticut school shooting last Friday. Adam Lanza allegdly killed his mother, Nancy Lanza, in her home before driving her car to the school and killing 26 people. The school's principal, Dawn Hochsprung, was one of the adults who died in the shooting.

As we previously reported, Connecticut shooter Adam Lanza was reportedly suffering from some kind of personality disorder. The guns found at the scene of the crime were legally registered to Lanza's mother, Nancy.

During the ABC interview, Krista Rekos described the agonizing period when she and her husband, Richard, tried to locate their daughter at the firehouse where the Sandy Hook students were kept after the Connecticut school shooting.

"I knew exactly what she was wearing, and I was hoping to see her little ponytail run around the corner, and her jacket and her black glittery Uggs that she had on that morning," Rekos said.

Krista Rekos' husband, Richard Rekos, then recalled the moment when police told a group of parents that 20 children had been killed in the Sandy Hook school shooting.

"We couldn't get a straight answer," Richard Rekos said. "There's so much panic and confusion when that announcement was made, the life was just sucked out of the room. And you know, I just point-blank found a state trooper and said, 'Are you telling me that standing here as a parent that my daughter is gone?' And he said, 'Yes.'"

The couple added that they were supposed to stay behind at the school to identify their daughter's body, but they couldn't bear to do it. Instead, Krista Rekos and her husband went home, where a state trooper came by early the next morning to tell them the devastating news.

"It just confirmed the nightmare, it's not real," Krista Rekos said. "It's still not real that my little girl who's so full of life and wants a horse so badly, and who was going to get cowboy boots for Christmas, isn't coming home."

Mediaite reports that Krista Rekos and her family also released a statement describing the daughter they lost that day at Sandy Hook Elementary School .

"Jessica was our first born," the statement read in part. "She started our family, and she was our rock. She had an answer for everything, she didn't miss a trick, and she outsmarted us every time. We called her our little CEO for the way she carefully thought out and planned everything. We can not imagine our life without her."

Krista Rekos also read from her daughter's diary during the ABC News interview. The mother noted that her daughter left a message of "I love you mommy" shortly before the Connecticut school shooting at Sandy Hook.

"It was like she knew we were going need something to help us get through this," Krista Rekos said. "That's just like what an amazing little girl she was."
