Shanann Watts' parents break their silence after daughter's tragic murder

The parents of Shanann Watts are finally speaking out after the murder of their daughter and her "miracle" little girls.

Frank and Sandra Rzucek will be talking about their daughter during an exclusive interview with ABC News. The network gave the public a sneak peek of the 20/20 segment to be aired on Friday night.

Frank knew exactly how to describe his late daughter:

"Just full of life, always out there trying to help people."

Mother Sandra smiled as she talked about her ambitious daughter:

"She was fun. Full of life. She did so many things. She had her hand in everything. She was amazing."

Shanann's life also looked amazing to those who followed her Facebook page. The 34-year-old shared lots of pictures and videos with the public.

Her parents also knew of a vision board that their daughter kept. According to Frank, it was "to make sure her children had everything they ever needed."

He added:

“She would do anything for her children. She just loved her children, and she wanted them to have everything growing up.”

When the kids came along, Shanann was still battling lupus, an autoimmune disease. After their births, Shanann considered her daughters to be "miracles."

Sarah said in the interview:

"They were her everything. They were her world. That was her dream [to be a mom] and then she battled lupus for a long time."

When asked if they believed Shanann was happy, her parents said "absolutely." Frank even asserted that she "was extremely happy."

But it all came to an end when Shanann was 15 weeks pregnant with her third child. After returning from a work trip, her husband Chris Watts horrifically murdered her and their two daughters.

At first, Chris denied any knowledge about the disappearance of wife Shanann, and daughters Celeste, three, and Bella, four. Then police found their bodies at Chris' work site.

He then claimed he had strangled Shanann after she murdered their daughters. However, the court determined that Chris, who was having an affair, killed all three of his family members.

According to Judge Marcel Kopcow, he wanted a "fresh start" with his mistress. Chris didn't speak throughout his trial. He was sentenced to life in prison following a guilty plea.

At the time, Sandra told Chris in court:

"I didn't want death for you because that's not my right. Your life is between you and God, and I pray he has mercy for you."

On Thursday, Chris was reportedly moved from Colorado to the Wisconsin Department of Corrections. He is set to be moved again.

A spokesman for the facility, Mark Fairbairn, said it was due to "security concerns" as Chris was deemed a "high profile offender."

Fairbairn said that the family and district authorities were aware of Chris' new location.

The interview of Shanann's parents will air tonight at 8 p.m. on ABC's 20/20.
