TUCSON - Day 26 and still no sign of missing 6-year-old Isabel Celis.

Her parents, Sergio and Rebecca, say they put her to bed around 11 p.m., Friday, April 20th.

The next day, Tucson Police started searching a 3-mile radius around the family home near Craycroft and Broadway.

Investigators have poured over at least a thousand leads.

The family continues to pray for the return of little Isabel. Last week, Child Protective Services barred the father, Sergio Celis, from seeing his two sons. The boys are now with their mother.

Neighbors were shocked to hear the family was separated.

David Pike says he didn't notice anything unusual when he saw the family just after a news conference on May 4th. He says he saw Sergio with the older son walking from the grandparents' house to the Celis' house.

"I said hi how is it going, is there anything our family do to help and Serg Sr. Looked at me and said just pray. And I said we can do that," Pike said.

Pike said a few minutes later he saw the wife, Rebecca, and the other son and also greeted them.

This past weekend he didn't see Sergio. "We seen mom and the boys in the car going towards the house, I mean walking down the street no we haven't seen them at all since a week ago."

Pike says they will continue to pray for Isabel's safe return.
