More than five days since 12-year-old Amber Harris was last seen, police and volunteers were searching her neighborhood door-to-door.

They were trying to figure out what happened after her friends saw her get off the school bus a few blocks from her home.

Officers showed a picture of the 12-year-old girl to everyone they saw -- asking if they had seen her.

Their answers were all the same

"No," said Omaha Police Officer Andrew Passo. "At this point, there is no further information."

"Someone around here knows something," said Melissa Harris, Amber's mother.

Harris says its' hard not to think of the worst.

"At first, of course, you think terrible things," she said. "That somebody has taken her and tortured her and killed her. Sometimes that comes to mind."

But Sunday, with more than a dozen officers walking their neighborhood and a mobile command center set up at Amber's bus stop, the family tried to stay positive -- waiting for Amber to call.

"In a way, I want to hear it ring," Amber's grandmother Ruth Nickens said. "In another way, it always just makes me just almost have a heart attack because I think I'll hear Melissa just sobbing. And I know if I hear that, it will not be a good thing. All we want is this child to be back."
