TUCSON, AZ - The parents of a 6-year-old girl who vanished from her Tucson home in April asked the nation to pray for her Thursday.
"We just want her home and we want people to keep praying for her so she comes home to us," said Isabel's mother Becky Celis.
Becky and Sergio Celis, Isabel's parents, told investigators they last saw their daughter at 11 p.m. Friday, April 20th.
Her mother, a nurse, was at work Saturday when her father went to wake her at 8 a.m. and discovered her missing, police said.
During their first, exclusive television interview, Isabel's parents Thursday told the "Today Show " that they are frustrated that it's taking so long to get her home.
"We understand they're doing everything possible," explained Isabel's father Sergio Celis. "We do feel sometimes that they're wasting time with us. Even though we know we have to be under the closest scrutiny absolutely understandable."
The couple asked to keep their eyes open, and to pray for whoever took her to have a change of heart and bring their playful daughter home.
"She's a girly-girl and she loves to get her makeup on and paint her nails," Isabel's mother Becky smiled.
An extensive landfill search and hundreds of tips from the public have done little to help in the search for Isabel Mercedes Celis.
Officials have not given up hope that Isabel is alive.
The Pima County Attorney's Office is offering a $6,000 reward, which includes an anonymous donation of $5,000, for information regarding Isabel.
