The search to find 12-year-old Amber Harris was kicked up a notch this week with the discovery of the girl's book bag at 21st and Lake.

The bag contained a notebook with Amber's name, some of her clothing and a text book.

For another Omaha mother who lost her daughter to crime, her case also remains unsolved.

The body of Rebecca Williams was found in June of 2003 and her mother fears the city has forgotten her daughter's killer is still on the loose.

"Right now, we're doing a lot of memory, watching home videos," said Shelly McCormick, Williams' mother. "Because our son still forgets. He was only 18 months when she disappeared and he doesn't remember her."

McCormick wants everyone to remember her 13-year-old daughter. She disappeared from a northwest Omaha park and her body was found in a wooded area less than half a mile from her home a little more than two weeks later.

"Because once someone kills, they're going to do it again," she said. "And I don't want this person out there. I have other children. There are other kids out there."

McCormick says she is still having a hard time dealing with her daughters' death and the investigation.

"I think that's what I have the hardest time with," she said. "We were never given any explanation as to why we should have to wait two weeks for someone to look for our daughter."

McCormick has been following media coverage of the Amber Harris case. The girl has been missing since November 29.

"I really feel for the mother," said McCormick. "I understand what she's going through. We've gone through it with unfortunate results. I think the main thing that keeps popping in my head is they need to search harder. The police need to search harder."
