TUCSON - Volunteers are not letting anything distract them from trying to bring Isabel Celis home.

"If this were my child who went missing," Holly Hansen said, "I wouldn't want people to forget. I wouldn't want people to stop trying."

The latest news about Child Protective Services increasing their involvement in the case is not something they dwell on.

"Until we know facts," Hansen said, "I don't think that it detracts at all from what's going on here."

They realize interest in the case is settling down.

"We do live in a world where everybody has a short attention span," Rockne Rios said, "but hopefully, they won't give up so easily."

They say they have given away more than one million flyers.

All the money they raised has gone toward publicity and the reward.
