The parents of Shanann Watts have spoken out for the first time, in an interview on ABC’s 20/20 that will air in full Friday night.

ABC released a clip of the interview ahead of Friday’s airing, in which Frank and Sandra Rzucek talk about their memories of their daughter and granddaughters, 4-year-old Bella and 3-year-old Celeste. All three were murdered by Chris Watts on August 13 of this year.

Shanann’s parents spoke of how happy Shanann was to raise her family, and her drive to provide her daughters with everything they could hope for. At the time of her death, Shanann had become a successful Multi-Level Marketer for a nutrition and fitness program called Thrive.

“Her dream was to help her entire family,” Sandra Rzucek said in the televised interview.

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

“She never gave up,” her father Frank said.
