Their daughter, Susan Powell, who disappeared in December 2009, loved the Christmas musical.
“We want more than anything to find our daughter,” Judy said.
Artist Michael McLean dedicated Tuesday's performance of “The Forgotten Carols” at Cottonwood High School to Susan.
“It reminds me just how fragile everything is,” McLean said. “I think what Susan was feeling when she heard the music is that she wasn’t alone.”
Chuck and Judy Cox met with McLean before the performance. They shared their emotions about Susan’s disappearance and about their son-in-law Josh Powell.
Josh killed his sons Charlie and Braden in February 2012 when he blew up his Washington state home.
“We don’t understand why he took the boys,” Chuck said.
The Coxes believe Josh felt that if he couldn’t have Charlie and Braden, no one could.
They said this Christmas will be bittersweet for them.
“Last year we were with the boys and they were helping decorate the Christmas tree,” Chuck said. “I didn’t want to put up a tree this year.”
The Coxes did put up a tree for their other grandchildren, but said the holidays will never be the same.
Despite the tragedies, the Coxes have faith in the West Valley City Police Department.
“My daughter will be found when it’s the right time for her to be found,” Chuck added.
The couple said prayers and their faith have helped them endure.
