She was a six-year-old girl, who disappeared from her home on a peaceful Saturday almost five years ago.
Police and the people who loved Isabel Celis still held out hope she'd be found alive. But now that hope is gone.
Even police who have seen so many things turn out badly held onto hope they could still find Isabel Celis alive.
That ended when DNA tests came back and confirmed the worst.
When Isabel Celis disappeared, Tucsonans poured out their hearts with hope that she could be found.
Now the only hope left is the hope police can find her killer.
"We believe there are people out there that may know something and they are willing to come forward with information that may be helpful. Don't assume that we have all the information. If people have tips, they should absolutely contact us of 88-CRIME."
Early on a Saturday almost five years ago. The girl's father woke up, could not find her but did find her window open and the screen broken out.
The story and the mystery went nationwide and worldwide without a break in the case until police found remains in Pima County earlier this month.
They sent them to an especially sophisticated DNA lab in Virginia, and the match confirmed the remains were the young girls.
Chief Christopher Magnus says even after almost five years police never stopped working the case.
Sometimes remains are found just by chance, a passer-by may find them.
The chief says in this case the investigation led police to the spot where they found Isabel Celis, but he will not elaborate on exactly how they found that spot or say where investigators are pointing their efforts now.
